This annual report reviews activities of the Technical Committee on Acoustical Oceanography (TCAO) from the 170th and 171st meetings of Acoustical Society of America (ASA) held in Jacksonville, Florida, in fall 2015 and Salt Lake City, Utah, in spring 2016, respectively. It has been a strong year for AOTC, with many well-attended sessions, a number of recipients of prestigious prizes and awards, and a resurgence in the number of student papers presented.
Two well-attended special sessions were organized by the TCAO at the Jacksonville meeting: 1) “Acoustics of High Latitude Oceans,” joint with SP, UW, and AB, chaired by Aaron Thode (Scripps) and co-organized by John Colosi (Naval Postgraduate School), and 2) “Passive-Acoustic Inversion Using Sources of Opportunity,” joint with SP and UW, co-chaired by Karim Sabra (Georgia Institute of Technology) and Kathleen Wage (George Mason University). In addition, there were 3 special sessions that AO co-sponsored: 1) “Direction of Arrival (DOA) Estimation, Source Localization, Classification, and Tracking Using Small Aperture Arrays,” co-sponsored with SP and UW and co-chaired by R. Lee Culver, (ARL, Penn State University) and Geoffrey H. Goldman, (US Army Research Laboratory), 2) “50 Years of Underwater Acoustics under ASA,” co-sponsored with UW, AB, and SP, chaired by David Bradley (Penn State University) and co-organized by John Colosi (Naval Postgraduate School), and 3) “Bioacoustics Research In Latin America,” co-sponsored with AB and co-organized by Juliana R. Moron (Universida de Federal de Juiz de Fora, Brazil) and Marie Trone (Valencia College). A very-well attended AO Hot Topics talk entitled Hot topics in “cold” acoustical oceanography was presented by Grant B. Deane (Marine Physical Laboratories, Scripps, University of San Diego), complementing the earlier session on the acoustics of high-latitudes. One of the highlights of this meeting was the 2015 Munk Award Lecture given by Carl Wunsch, an Emeritus Professor of Physical Oceanography at the Massachusetts Institute of Technology, during the Wednesday afternoon plenary session, entitled “Ocean acoustic tomography: Past, present, and maybe future”. The Munk Award is granted jointly by The Oceanography Society, the Office of Naval Research, and the Office of the Oceanographer of the Navy for distinguished research in oceanography related to sound and the sea. There were also an encouraging number of student papers presented, with the first place prize given to Katherine Wolfe, from the Georgia Institute of Technology, for her paper entitled “Optimized extraction of coherent arrivals from ambient noise correlations in a rapidly fluctuating medium, with an application to passive acoustic tomography”, and second place prize given to Graham Warner, from the University of Victoria, for his paper entitled “Environmental inversion using bowhead whale calls in the Chukchi Sea”.
The Salt Lake City meeting was punctuated by the presentation of the 2016 R. Bruce Lindsay Award to Megan S. Ballard, a member of the AOTC, for contributions to underwater acoustic propagation modeling and inversion techniques in acoustical oceanography. The R. Bruce Lindsay Award is presented in the spring to a member of the Society who is under 35 years of age and who has been active in the affairs of the Society and has contributed substantially, through published papers, to the advancement of theoretical or applied acoustics, or both. Also at Salt Lake City, the 2016 Medwin Prize was awarded to Thomas Weber from the University of New Hampshire, also an AOTC member. The prize award lecture will be presented at the Hawaii meeting. The Medwin Prize recognizes the accomplishments of young and mid- career scientists involved in research that addresses the effective use of sound in the discovery and understanding of physical and biological parameters and processes in the sea. The new incoming TCAO chair was announced at Salt Lake City, and a hearty congratulations goes to John Colosi (Naval Postgraduate School). There were three well-attended special sessions organized by the TCAO at the Salt Lake City meeting: “Acoustic Consistency of Ocean Models,” co-sponsored by SP, and organized by Tim Duda (WHOI) and Bruce Cornuelle (Scripps), 2) “Noise Impacts from the Industrialization of the Outer Continental Shelf and High Seas,” co-sponsored by AB, and organized by Michael stocker (Ocean Conservation Research), and 3) “Acoustical Oceanographic Tools for the Study of Marine Ecosystems,” co-sponsored by AB, and organized by David Barclay (Dalhousie University) and Wu-Jung Lee (Johns Hopkins University). Though the TCAO seems to be generally skeptical of live broadcasting of special sessions, the latter two special sessions were broadcast live and seemed to enjoy strong on-line attendance. In addition, there was a special session on “Sediment Characterization Using Direct and Inverse Techniques,” that AO co-sponsored with SP and UW and which was co-chaired by David Knobles (KSA LLC) and Preston Wilson (University of Texas at Austin). There were again a very healthy number of student papers presented, with the first place prize given to Scott Loranger, from the University of New Hampshire, for his paper entitled “An evaluation of the frequency response of hydrocarbon droplets”, and the second place prize was a tie between Jacquelyn Kubicko, for her paper entitled “Passive ocean acoustic tomography using ships as sources of opportunity recorded on an irregularly spaced free-floating array: A feasibility study”, and Graham Warner, for his paper entitled “Time-difference-of-arrival localization of bowhead whales using asynchronous recorders”.
This report is my last as Chair of the AO Technical Committee. I want to close by thanking the volunteers who made the activities of the AO Technical Committee possible this year. I look forward to continuing to work with the AO Technical Committee and the ASA community more broadly.
It’s been a busy and productive year at TC AB, with many special sessions at the two ASA conferences (Jacksonville, FL, November 2015; and Salt Lake City, UT, May 2016) and a large number of student presentations. We’ve seen the first sessions being streamed live online—very successfully. The ASA’s Strategic Plan was released and the ASA began starting its implementation by setting up four task forces on which TC AB is, of course, represented.
In Jacksonville, FL, TC AB (co-)hosted sessions on: Comparative Neurophysiology of the Auditory System in Honor of Albert Feng; Acoustics of High Latitude Oceans; Direction of Arrival (DOA) Estimation, Source Localization, Classification, Tracking using Small Aperture Arrays; Soundscape and its Application; Bioacoustics Across Disciplines: Detecting and Analyzing Sounds; Bioacoustics Across Disciplines: Emitting Sound; Bioacoustics Poster Session; 50 Years of Underwater Acoustics under ASA; Avian Bioacoustics; Bioacoustics Research In Latin America; and New Discoveries in Bat Vocal Communication.
We had 21 entries for TC AB student presentation awards. The oral presentation award went to Grace Smarsh, Singing away from home: Song is used to create and defend foraging territories in the African megadermatid bat, Cardioderma cor. The poster presentation award was won by Yumi Saito, Rats became positive or negative states when listening to specific vocalizations.
In Salt Lake City, UT, TC AB (co-)hosted sessions on: Comparative Hearing Honoring Dick Fay; Cetacean Bioacoustics; AB General Poster Session; Effects of Noise on Animals; Airborne Automatic Animal Bioacoustics; Noise Impacts from the Industrialization of the Outer Continental Shelf and High Seas; and Acoustical Oceanographic Tools for the Study of Marine Ecosystems.
Due to this being a smaller meeting than the one before, TC AB had fewer student entries for its student presentation awards, which were won by Adrienne M. Copeland, Relative abundance of sound scattering organisms in the NW Hawaiian islands is a driver for some odontocete foragers; and Marielle Malfante, Automatic fish sounds classification.
Thanks to Ben Taft, our TPOM for both the Jacksonville and Salt Lake City meetings.
Special sessions suggested for future ASA meetings can be found on the TC AB website.
TC AB Technical initiatives that were approved in the past year are student and postdoc travel support to the International Congress of Neuroethology in Montevideo, Uruguay, 2016; to the Effects of Noise on Aquatic Life conference in Dublin, Ireland, 2016; to an Airgun Modeling Workshop in Dublin, Ireland, 2016; to the SeaBASS summer school in Pennsylvania, USA, 2016; to the Listening for Aquatic Mammals in Latin America Workshop, 2016; and to the Animal Acoustic Communication conference in Omaha, Nebraska, 2017.
TC AB is actively involved in the development of acoustic standards. We currently have working groups on Underwater Passive Acoustic Monitoring for Bioacoustic Applications; Description and Measurement of the Ambient Sound in Parks, Wilderness Areas, and Other Quiet and/or Pristine Areas; Noise and Vibration in Animal Laboratory Facilities; and Evoked Potential Testing of Toothed Whale Hearing. Anybody interested in participating, please contact TC AB.
Last but not least, JASA is looking for additional Associate Editors in AB.
Thank you to all the members of TC AB for your support and involvement in the various activities of the ASA.
Once again the Technical Committee on Architectural Acoustics (TCAA) continues its focus on:
1. A rich diversity and relevance at ASA Conference Events
2. Outreach and Advocacy in the discipline during and between commences
3. A steady Focus on Future Growth
…In a manor to promote continuity and organizational vitality.
TCAA Organizational Abstract:
The state of the TCAA is very healthy due to the long history of visionary professionals that have lead passionately over the years.
A key to the health of TCAA is the professional diversity in application ranging from Academic, Research, Consultants, Manufactures, Architects, and more. This diversity provides stability in economically adverse cycles, a rich pool of talent and serving capacity, as well as “full loop” interest from concept and research to application and solution.
Another key to the health and vitality of TCAA is leadership development. The TC develops leadership, experience and continuity by promoting team over point person approach in a verity of important roles. As example the TCAA Chair appoints a secretary to a) assist in the chair’s functions and b) learn the process, procedures and duties of the chair developing an excellent candidate as future chair. We are moving forward to implement a similar continuity model across the Medals & Awards, Members, and other Committees and Subcommittees.

As her first act as Chair Erica asked Eric Reuter to serve as TCAA Secretary which Eric graciously accepted to serve.
Outreach and Advocacy efforts took many forms this year:
American Institute of Architects Continuing Education System
The Technical Committee on Architectural Acoustics (TCAA) continues to be a Registered Provider in the American Institute of Architects (AIA) Continuing Education System (CES). The TCAA has developed a standardized introductory short course for architects, called “Architectural Acoustics”. An architect can earn one continuing education unit (CEU) by attending this short course, if it is presented by a qualified member of TCAA. The course covers topics in sound isolation, mechanical system noise control, and finish treatments. The qualifications to be an authorized presenter are: 1) Current ASA member in good standing, 2) Current TCAA member in good standing 3) Has attended the AIA/CES short course, organized and offered periodically at ASA conventions.
Publications from and related to Architectural Acoustics
With special thanks to Erica Ryherd, David Bradley, and Lauren Ronsse the “Worship Space Acoustics: 3 Decades of Design” book has been published. This follows a proven concept as demonstrated most recently in the drama theater book.
Classroom Acoustics information booklets continue to serve as a companion for ANSI S12.60 standard, with architects, educators and parents as the target audiences.
WG44; Members of TCAA joint with TCNoise, have completed the draft of S12.70 Standard for Speech Privacy in Healthcare. The final draft is in review at the time of this report.
The TCAA body is fully engaged and supportive of the Strategic Leadership Plan for the Future.
Our Focus on Future Growth is realized in the following ways:
Students, diversity in application participation, and industry relevance.

The Technical Committee on Noise (TCNS) has continued to be active in 2015-2016. Kirill V. Horoshenkov was received as an ASA fellow at the Jacksonville meeting and Kent Gee and Christine Erbe were received as ASA Fellows at the Salt Lake City meeting. Three Young Investigator Awards were given for the Jacksonville meeting to Matthew Kamrath, Brenna Boyd and Matthew Calton and three awards were given in Salt Lake City to Christopher Jasinski, Matthew Calton and Pranav Pamidigantham. The ASA gave the Distinguished Service Citation to Susan Blaeser for dedicated management of the Acoustical Society of America standards program. We wish Susan well and thank her for tremendous service to the TC Noise in developing standards, managing the diverse personalities of standards participants and for representing the Acoustical Society of America and the United States in international standards activities. Susan’s replacement is Neil Stremmel and we look forward to his role in managing standards for the society.
TC Noise notes the passing of our dear colleague, Louis Sutherland on February 23, 2016. Lou was a fellow of the Acoustical Society of America (ASA). Lou was one of the longest serving members of the international acoustics community and one of the most prolific. In a career lasting over 60 years his main areas of research involved studies of human and structural response to noise, sonic boom and blast, but his contributions to the fields of acoustics and vibration have been much more diverse and have included topics such as atmospheric absorption, aircraft noise measurement and modeling, low-frequency noise, classroom acoustics, and acoustic testing.
This year, one highlight was the inaugural award for the Leo and Gabriela Beranek Scholarship in Architectural Acoustics and Noise Control. Leo and Gabriela have endowed the scholarship to provide for awards over the course of the next ten years to an outstanding candidate in Architectural Acoustics and/or Noise Control. William Murphy (Chair TCN), Kenneth Goode Jr. (Chair TCAA), Damian Doria, and Tony Hoover worked with the Beraneks to develop the application process and to evaluate seven candidates. Andrew Hulva was notified following the Salt Lake City meeting that he had been selected as the recipient of the 2016 Beranek Scholarship.
In addition, TC Noise, TC Architectural Acoustics and TC Engineering Acoustics were informed that the Winker family has endowed the Frank and Virginia Winker Memorial Scholarship for Graduate Study in Acoustics. Christopher Struck, ASA Standards Director, is chairing the scholarship committee and has adapted the materials from the Beranek Scholarship to meet the requirements of the memorandum of understanding with the Winker family. The Acoustical Society is indebted to the leadership of Carl Rosenberg and the ASA Foundation for the management of these important scholarships.
The 170th meeting of the ASA was held in Jacksonville FL. There were 59 noise papers in 7 noise sessions. Eric Reuter chaired the session on Environmental and Community Noise. Brigitte Schulte-Fortkamp, Bennett Brooks co-chaired a session on Soundscape and its Application. Hilary Gallagher and Richard McKinley guided two sessions of explosive discussion on the topic of Damage Risk Criteria for Noise Exposure. Debate quieted down as Melissa Theis, Elizabeth McKenna, and William Murphy co-chaired a session on The Role of Fit-Testing Systems for Hearing Protection Devices. The session chaired Patricia Davies and Colin Novak provided insight into Thoughts on the Next Generation of ANSI Loudness Standards. Nancy Timmerman, Robert Hellweg, Paul Schomer, Ken Kaliski helped us to navigate the turbulent controversies of Wind Turbine Noise. And finally, Scott Sommerfeldt led a session of a mixture of several papers – the Noise Potpourri.
The 171st meeting of the ASA was held in Salt Lake City, UT. There were 59 noise papers in 8 noise-led sessions. As well, TC Noise cosponsored three sessions in Architectural Acoustics and one session in Animal Bioacoustics. Eric Reuter chaired two sessions on Community Noise. Ben Faber made us smarter in the use of our mobile devices by chairing the session on Acoustic Apps for Noise Measurements. Steve Pettyjohn and James Phillips helped to get us in shape with a session on Noise and Vibration Impacts in Crossfit Training Facilities. The session on Statistical Learning Techniques in Noise Research was chaired by Jonathan Rathsam and Ed Nykaza. Nancy Timmerman, Ken Kaliski, Bob Hellweg, Paul Schomer co-chaired two sessions on Wind Turbine Noise. Finally, Blaine Harker chaired the session on Topics in Noise Control.
Thanks to the following people who have represented TCNS within the ASA during this time: Ken Cunefare on the Medals and Awards Committee, Alex Case on the Membership Committee, Matt Blevins and Jonathan Weber on Student Council, Rich Peppin on ASACOS (Committee on Standards), Christopher Struck, Standards Chair and Ken Roy on Public Policy. The JASA Associate Editors for Noise have been G. Brambilla, Ben Cazzolato, Sandford Fidell, Kiril Horoshenkov, R. Kirby, Brigitte Schulte-Fortkamp.

Chair, TC Noise 2014-2018
170th Meeting of the ASA in Jacksonville, FL
Special Sessions for the 170th meeting included: Phononic Metamaterials (Joel Mobley), Acoustic Characterization of Critical Phenomena (Josh Gladden & Veerle Keppens), General Topics in Physical Acoustics I & II (Mike Haberman), Launch Vehicle Acoustics I & II: Acoustics of Launch Vehicles and Supersonic Jets (Kent Gee & Tracianne Neilsen)
This meeting marked the first to include Live Streaming of select sessions as a pilot project. The Acoustic Characterization of Critical Phenomena session was streamed. Comments from remote viewers were generally very positive and some suggestions were incorporated for the next meeting.
The PATC Twitter feed (@ASAcousticsPATC) went live for this meeting. It was quickly recognized that more social media savvy people need to be involved with generating tweets. Volunteers are welcome and can contact Josh Gladden (firstname.lastname@example.org).
171st Meeting of the Acoustical Society in Salt Lake City, UT
PATC Special Sessions for the 171st meeting included: Atmospheric Acoustic Phenomena (Jericho Cain, John Paul Abbott), Computational Methods in Physical Acoustics (Amanda Hanford, Keith Wilson), Multiple Scattering (Valerie Pinfield), Vortex Beams and Radiation Torque Physics (Likun Zhang, Philip Marston), Nuclear-powered thermoacoustics (Steve Garrett)
The Live Streaming pilot project expanded from 4 sessions in the 170th meeting to 19 sessions for this meeting. This level is hitting a threshold for the volunteer Task Force to handle.
The new ASA Organization Chart was presented and discussed. There was general agreement that the changes were positive and reflective of the Strategic Plan.
The upcoming Physical Acoustics Summer School was discussed. 24 graduate students representing 16 universities and 4 countries have been accepted. This represents the broadest group of students to attend a PASS and will likely lead to larger applicant pools in the future. Funding PASS remains a challenge and various options are being explored to augment ASA support including charitable donations, Federal support, and corporate support.
The Long Range Sound Symposium will be held in Oxford, MS on Sept. 20-21, 2016 and hosted by the National Center for Physical Acoustics. Roger Waxler (email@example.com) is organizing the meeting.
There was discussion about forming a Computational Acoustics Specialty Group. Researchers in this area cut across a wide range of Technical Committees. To formally create a Specialty Group, 50 members must claim this as their primary research area. This effort is being led by Keith Wilson(David.K.Wilson@erdc.dren.mil) and Amanda Hanford (firstname.lastname@example.org).

The P&P held no special sessions during the fall meeting in Jacksonville but some members of our area traveled to the meeting to attend the Award Ceremony during which Roy Patterson received the Silver Medal Award. Roy chose to receive his award during the fall meeting to make it possible for David Green, one of the P&P greatest researchers who is now retired, to join the celebration.
Our members continued their significant involvement in the Society. The past-President, Judy Dubno, and the past-Vice President, Barbara Shinn-Cunningham, completed their three-year leadership cycle at the conclusion of the spring meeting. Andrew Oxenham is currently a member of the Executive Council.
The spring meeting in Salt Lake City was well-attended by the P&P members. The P&P was the main sponsor of six special sessions: “Approaches to Improve Speech Understanding in Noise” organized by Eric Healy, Ying-Yee Kong, and Tao Zhang, “Acoustic Outreach to Budding Scientists: Planting Seeds for Future Clinical and Physiological Collaborations” organized by Anna Diedesch and Adrian K. C. Lee, “Quantitative Methodology in Both Physiological and Psychophysical Data Analysis Workshop” organized by Daniel McCloy, Ross Maddox, and Hari Bharadwaj, “Beyond the Audiogram: Influence of Supra-threshold Deficits” organized by Agnes Leger, and Christopher Plack, “Lessons from Interrupted Speech: Methods and Models” organized by Valeriy Shafiro, and “Spatial Hearing” organized by Ewan Macpherson. All special sessions met with a great interest and were well received. Two of the special sessions were live-streamed and the comments from P&P members unable to attend the meeting who logged on to remotely participate were very positive.
Alan Palmer (University of Nottingham, UK) was the fourth recipient of the William and Christine Hartmann Prize in Auditory Neuroscience. Alan delivered a fascinating Auditory Neuroscience Prize Lecture entitled “Bridging the chasm: Animal physiology and human psychophysics” mixing a great scientific content with a dose of great British humor. The lecture attracting many more people than the room could hold.
Ian Bruce, Micheal Dent, Karen Helfer, and Christopher Stecker became new Fellows of the Society.
The P&P Technical Committee meeting in Salt Lake City was well attended and was live-streamed. During the meeting, reports were given by the JASA Associate Editors for Psychological and Physiological Acoustics, JASA-EL, and POMA. The following Technical Committee members were thanked for their three-year service on the Committee: Michael A. Akeroyd, Richard L. Freyman, Adrian K. C. Lee, Ruth Y. Litovsky, Ewan A.

The following six members started their three-year term at the meeting in Salt Lake City: Huanping Dai, Karen Helfer, Pamela Souza, Elizabeth Strickland, Sarah Verhulst, Matthew Winn. We also held our annual elections to select new members of the P&P Technical Committee whose term will begin at the meeting in Boston (spring, 2017). The following members were elected: Joshua Bernstein, Emily Buss, Hari Bharadwaj, Monita Chatterjee, Ross Maddox, Christopher Shera, and Christian Stilp. Many thanks to Ying-Yee Kong and Anna Diedesch for running the elections and counting the ballots during the meeting.
We thank Christopher Brown for being our representative at the remotely-held Technical Program Organizing Meeting (TPOM) for the meeting in Salt Lake City.
We also thank Erica Hegland for maintaining and updating the P&P webpage on the ASA website.
P&P members serve on a number of ASA Committees. Brenda Lonsbury-Martin was nominated by the ASA President, Christy Holland, for the Chair of the Medals and Awards Committee. Judy Dubno became the P&P representative on this committee. Adrian K. C. Lee agreed to be our liaison to the Committee on Education in Acoustics. Adrian also volunteered for the Task Force working on improving the process of publication in JASA and JASA-EL.
We extend special thanks to Anna Diedesch for her excellent service as the P&P representative to the Student Council. Anna’s term ended this spring and our new representative is Kelly Whiteford, a student from the University of Minnesota.
The P&P Technical Committee will continue traditional Technical Initiatives, which include travel support for invited speakers, student receptions, and homepage updating, while also focusing on implementing innovative initiatives such as workshops and satellite meetings facilitating collaborations and attracting new members from underrepresented research areas (clinical, physiological, industry, education) to the Society. Suggestions for uses of P&P Technical Committee funds for new Technical Initiatives are welcome and should be sent to the Chair of the P&P Technical Committee.
The Technical Committee on Signal Processing in Acoustics (TCSP) had a very productive year with a wide ranging set of special sessions that attracted much interest and an impressive set of candidates for our Best Young Presenter Awards.
In Jacksonville, diverse issues associated with localizing acoustic sources continued as an important area of inquiry for our community. The meeting brought together researchers in special sessions on “Direction of Arrival (DOA) Estimation, Source Localization, Classification, and Tracking Using Small Aperture Arrays” organized and chaired by Lee Culver (Penn State Univ.) and Geoffrey Goldman (US Army Res. Lab). The technical challenges that attend some of the most fundamental issues in acoustic detection and estimation were addressed during a special session on “Random Matrix Theory in Acoustics and Signal Processing” organized and chaired by Jim Preisig (JPAnalytics). Jacksonville also saw an abundance of contributed talks in two well attended sessions, “Detection, Feature Recognition, and Communication” chaired by Geoffrey Edelmann and “Algorithm, Analysis, and Beamforming” chaired by John Buck (UMassD).
The TCSP was very proud at the Jacksonville meeting to see Brian G. Ferguson, Principal Scientist, Maritime Division, Defence Science and Technology Organization, Australia receive the Acoustical Society of America’s Silver Medal in Signal Processing in Acoustics for contributions to in-air and in-water acoustic classification, localization and tracking.
At Salt Lake City we had 4 vibrant special sessions. We saw new and practical research on the topic of “Small Unmanned Aerial Vehicle (UAV) Detection, Tracking, and Classification” organized and chaired by Lee Culver and Geoffrey Goldman and a special session on Acoustic Array Systems and Signal Processing organized and co-chaired by Mingsian Bai (National Tsing Hua Univ.) and John Buck (Univ. MA Dartmouth). Signal processing issues associated with matched field processing continued to draw attention with a special session “Comparison of Beamforming, Matched-Field Processing, and Time Reversal Techniques” organized and co-chaired by Brian Anderson (BYU). We also had a special session on issues associated with “Detection and Estimation in Uncertain Acoustic Environments” organized and chaired byPaul Gendron (UMassD). Lastly, Edmund Sullivan (EJS Consultants) and Brian Anderson chaired a “General Topics in Signal Processing” session bringing together a nice set of acoustic signal processing contributions.
The TCSP sponsored the 16thGallery of Acoustics (GoA) event in Salt Lake City. The GoA provides an open forum forresearchers to display novel and aesthetically inspiring acoustical phenomena. The event emphasizes the interdisciplinary, and sometimes even artistic nature of acoustics. The GoA was organized by Michael Muhlestein (UT Austin) and TCSP members served to judge and rank the contributions. This year’s first place winner was Brent Reichman with his “Acoustics in Flight” display. The second place winner was Claire Pincock with her “Visual Directivity” display.
The TCSP continues to sponsor its Best Young Presenter Award with a diverse and talented group of contestants this year. The winner of the 170th Meeting was Atulya Yellepeddi (MIT) with his presentation “The surprising sample covariance matrix: Unexpected characteristics and understanding them“. The winner at the 171th Meeting in Salt Lake City was Christopher Verlinden (UCSD) for his presentation “Extrapolation of measured correlation replica fields in passive acoustic source localization“. Each winner received an award of $500. Due to the quality and breadth of presentations this year we recognized a number of runner up presentations; Michael-Thomas Ramsey (Nottingham Trent Univ) was recognized for his presentation “Automated detection of honeybee begging signals from long term vibration monitoring of honeybee hives” (170th meeting), Sarah M. Young (BYU), for her presentation “ ‘Knocked Over!’: A visual demonstration of time reversal focusing using bending waves in a thin plate” (171st Meeting) and Danielle Lynd, (OSU), “Acoustic beamfolding, new potentials enabled by interfacing reconfigurable origami and acoustic structures” (171st Meeting). We are very proud of the student presenters that continue to enliven the TCSP and are willing to undergo the scrutiny that attends competing in this challenging environment.
TCSP is thankful for the conscientious service of Ning Xiang (RPI) and Said Assous (Univ. Weatherford) as Technical Program Organizers for the Jacksonville and Salt Lake City meetings. Many technical and logistic considerations need to be taken into account to ensure a successful meeting and we are indebted to their care and energy. We welcomePaul Hursky (HLS) as the TCSP Associate Editor for the Proceedings of the Meetings on Acoustics. Paul replaces Sean Lehman. We are also pleased to have John Buck represent the TCSP before the ASA Committee on Education. James Preisig continues to serve as the TCSP representative to the Membership Committee while Edmund Sullivan continues as our representative to the Medals and Awards Committee. Ben Faber (Faber Acoustical) will serve as TCSP representative to the ASA Committee on Standards. Ben replaces Charles Gaumond (Aria) in this role. Charles is a former TCSP chair and a cherished mentor to many TCSP members. The TCSP website has been exceptionally maintained by Brian Anderson. In Salt Lake City the TCSP was pleased to establish Jeff Rogers (NRL) as the new organizer for the Best Young Presenter in Signal Processing Competition. Jeff replaces Philippe Moquin, who ably served in this role for the past 3 years.
The TCSP is ably served by a talented and conscientious group of associate editors and we are immensely grateful for their patience and careful service this year.

The two ASA meetings went very smoothly this year. We are grateful to our Technical Program Organizing Meeting (TPOM) representative, who sorted papers, arranged the technical programs, and determined presentation rooms. The representative was Alexander Francis for both the Jacksonville and Pittsburgh meetings. The ASA has successfully transitioned to an online organizing meeting, and Alexander Francis has served in that capacity since the start of the process. His service in this regard has been invaluable. In addition, Richard Morris served as the General Chair and I, Catherine L. Rogers, served as Technical Program co-Chair (with Judy R. Dubno) for the Jacksonville meeting.
To create stimulating and focused sessions, we sponsor special sessions every year, which focus on themes of interest to the speech community. The Jacksonville meeting had two special sessions sponsored by the Speech Communication Technical Committee: one organized by Cynthia Clopper entitled “Advancing methods for analyzing dialect variation” and a special session organized by Mary Beckman and Valerie Hazan entitled “Development of Speech Production (and Perception) across the Lifespan.”
The Pittsburgh meeting had two special session sponsored by the Speech Communication Technical Committee on topics related to the both speech perception and speech production and one (coplanned) jointly sponsored special session: a named special session in honor of Ken Stevens, entitled “Celebration of Kenneth N. Stevens’ Contributions to Speech Communication: Past, Present, Future,” organized by Stephanie Shattuck-Hufnagel and Helen Hanson, and a special session entitled “Listening Effort,” organized by Alexander Francis and Christian Fullgrabe; Catherine Rogers participated in the organization of a named special session in honor of Karl Kryter, co-sponsored by several TCs, entitled “Sixty-Fifth Anniversary of Noise and Health: Session in Honor of Karl Kryter II.”
The Speech Communication Technical Committee has also participated in the recent development of live streaming of a limited number of sessions, which began at the Jacksonville meeting and is continuing.
Stetson Scholarship. The SCTC also evaluates the Stetson Scholarship applications. The awardees for 2015 were Katherine M. Dawson (Graduate Center for the City University of New York) and Matthew I. Lehet (Carnegie Mellon University, Pittsburgh). The review committee was composed of the following persons in 2015: Suzanne Boyce, Kate Bunton, Rachel Theodore, Amy Neel and Stefan Frisch.
Silver Medal in Acoustics. For nominations for the Silver Medal in Acoustics to be forwarded to the Medals and Awards committee, four complete dossiers are required. In 2015, four full dossiers were complete and the committee met to discuss and rank the applicants. The committee consisted of the current SCTC chair and the two previous chairs: myself (Catherine Rogers), Benjamin Munson and Carol Espy-Wilson. John Ohala was awarded the Silver Medal in Acoustics at the Jacksonville Meeting (fall 2015) of the Acoustical Society of America.
Student Activities In our continuing effort to promote student participation in ASA meetings, the Speech Technical Committee sponsored two student activities at each meeting, a competition with a cash award for best student poster and evening receptions in Jacksonville and Pittsburgh. In Jacksonville (Fall 2015), the winner was Cynthia Blanco ($300), University of Texas at Austin, and second prize went to Sarah Hamilton, University of Cincinnati. In Pittsburgh, the winner was Dominique Simmons, University of California, Riverside ($300) and the second prize was William Bologna, University of Maryland ($200).
The student reception, which is joint with other technical committees, is intended to allow students to meet more senior ASA members informally. The receptions were well attended.
The student papers were judged by SCTC members. We thank Dan Fogerty, Jennell Vick, and Patrick Reidy for coordinating this competition for the Pittsburgh and Jacksonville meetings.
Revision to Student Paper competition. As stated in the previous report, the Speech Communication TC changed the Best Student Paper competition to a poster only (rather than poster or oral paper presentation) competition. This was begun at the Pittsburgh meeting. The wording in the call for papers was changed to make it clear that only poster presentations would be considered for the Best Student Paper competition. The organizers of the judging noted that the process did seem easier and fairer when only poster presentations were considered.
The Structural Acoustics and Vibration Technical Committee (SAVTC) had a successful year of special sessions sponsored by the committee and hosted Student and Young Presenter competitions at all of the meetings. This annual report covers SAVTC activities and meetings occurring during the one-year 2015-16 period beginning after the spring 2015 ASA Pittsburgh meeting.
James Phillips ended his three-year term as SAVTC chair at the conclusion of the Pittsburgh meeting and was relieved by Robert Koch who then began his 2015-2018 term as chair of the SAVTC. The SAVTC thanks James for his excellent and active work as chair during 2012-2015.
