This annual report reviews activities of the Technical Committee on Acoustical Oceanography (TCAO) for the 174th and 175th meetings of Acoustical Society of America (ASA) in New Orleans, Louisiana and in
Minneapolis, Minnesota. While we took our foot off the gas pedal this year after two internationally coordinated meetings in the previous year the AOTC enjoyed a wonderfully productive and eventful year.
A highlight is always our special sessions where we heard from scores of our talented researchers including 20 student papers. Here we focused on the topics of (1) Oceanographic contributions to ocean soundscapes, (2) Acoustic scattering from hydrocarbons and hydrothermal vent systems, (3) Biological effects on seabed geoacoustics, (4) Acoustics in estuaries, bays, inlets, fjords, and rivers, (5) Acoustic seabed characterization, and (6) Ambient noise oceanography in polar regions. I thank all my skilled session organizers for their successful planning and execution of their sessions, many of which were live broadcast.
Over the year there were also several awards to be celebrated. At the New Orleans meeting Woods Hole Oceanographic Institution (WHOI) Senior Scientist Dr. Andone Lavery was the recipient of the 2017 Walter Munk Award where she delivered the prize lecture entitled “New platforms, technologies, and approaches for remote inference of physical and biological parameters using acoustic scattering techniques.” Her citation reads “Through discrimination between the scattering by zooplankton and physical microstructure using broadband acoustic measurement methods and models, Andone Lavery has quantified important biological and physical parameters leading to new understanding of both ocean physical processes and marine biology.” Also at the New Orleans meeting we acknowledged AO founding father Michael Buckingham for his Pioneers of Underwater Acoustics Silver medal, awarded to him by the Underwater Acoustics Technical Committee. Michael’s citation reads “For contributions to the understanding of ocean ambient noise and marine sediment acoustics.” Following along at the Minneapolis meeting WHOI Associate Scientist Y. T. Lin was recognized with the AOTC Medwin Prize. Dr. Lin’s prize lecture was entitled “Three-dimensional shallow water sound propagation and applications toward acoustical oceanography,” and his citation reads “For fundamental advances in 3-D shallow water acoustics and applications to geoacoustic inversion and marine mammal acoustics.”
The AO students also shined during this past year with several exemplary papers. Award winners for New Orleans were in first place Elizabeth Weidner of the University of New Hampshire (UNH) with her paper entitled “Investigating bubble transport and fate in the watercolumn with calibrated broadband split-beam echosounder data” and in second place Jay Johnson of the University of Texas at Austin (UTA) with his paper “Variations in ultrasonic transmission behavior along seagrass leaf blades.”
In Minneapolis the first place paper was given by Josee Belcourt of the University of Victoria with the title “Gradient-based Bayesian geoacoustic inversion for sediment properties at the New England mud patch” and getting equal second places was Matthew Zeh of UTA with his talk entitled “Acoustical characteristics and contributions of bubbles released from melting glacier ice” and Elisabeth Brown from Rensselaer Polytechnic Institute for her paper entitled “Implications from a clay/silt suspension model of mud for data from the Seabed Characterization Experiment.” Well done students and I must say you made the judges life quite difficult because of the high quality of your work.
Continuing on the topic of awards, the AO and Underwater Acoustics (UW) technical committees are pleased to announce the establishment of the yearly Urick prize for the best AO or UW student paper published in the Journal of the Acoustical Society. The $500 prize is named in honor of Dr. Robert Urick of Catholic University of America who authored the classic and still very popular text book Principles of
Underwater Sound. We thank Charles Wiseman for helping establish the prize by offering to use a portion of the royalties from an upcoming reissuing of the Urick text. We also thank Jim Miller, Chair of the Acoustical Society Foundation Board for turning the idea into a reality.
Last, I want to thank everyone in the TC for all the effort that they put out this year in creating an energetic and dynamic atmosphere in AO and the greater society as a whole. We look forward to a productive and exciting year ahead.

After two very large meetings in a row (Honolulu, December 2016 and Boston, June 2017), the recent two meetings (New Orleans, December 2017 and Minneapolis, May 2018) were smaller and very peaceful for Animal Bioacoustics.
In New Orleans, we had five special sessions: “Bioacoustic Contributions to Underwater and Terrestrial Soundscapes,” “Neurophysiology of Echolocation,” “General Biosonar,” “General Bioacoustics,” and a session
“In Memory of George Ioup: Acoustics in the Gulf of Mexico.” Thirteen students entered the Animal Bioacoustics Student Presentation Award Competition, with Kali Burke taking first prize for her presentation on “Exposure-induced changes in laboratory mouse ultrasonic vocalizations” and Jack LeBien taking second prize for his presentation on “Species-level classification and clustering of beaked whale echolocation recordings.”
In Minneapolis, we had five special sessions: “Bat and Biomimetic Sonar,” “Plant Bioacoustics,” “Lessons on Auditory Perception from Exploring Insect Hearing,” “Animal Sound Production and Hearing,” and “History of Animal Bioacoustics.” The latter session highlighted research achievements in Animal Bioacoustics from the past century and was extremely well received, with requests to host this session again in the near future. Again, 13 students entered the Student Presentation Award Competition, with Jay Johnson winning first prize for “Ultrasonic transmission behavior in Posidonia oceanica rhizomes” and Xavier Mouy winning second prize for “Analysis of haddock (Melanogrammus aeglefinus) sounds recorded in the Northwest Atlantic.”
In terms of Animal Bioacoustics Technical initiatives for the year 2018, the ASA generously supported the International Congress of Neuroethology in Brisbane, an Animal Sonar Workshop in Brisbane, and the SeaBASS summer school in New Hampshire. Our Technical Committee is actively involved in the development of acoustic standards. We currently have working groups on the Effects of Sound on Fish and Turtles; Towed Array Passive Acoustic Operations 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; Auditory Evoked Potential Testing of Toothed Whale Hearing; and Acoustic Metadata for Passive Acoustic Monitoring. Everybody is welcome to joint and actively participate.
Thank you to all the members of the Animal Bioacoustics Technical Committee for your support and involvement in the various activities of the ASA.
The Technical Committee on Architectural Acoustics is active and healthy, with 275 members and strong engagement at ASA national and regional meetings throughout the year.
Eric Reuter and Ana Jaramillo have completed their second year as Chair and Secretary and will serve until the spring of 2019.
Matthew Neal has done a great job in his first year as our Student Council Representative.
New Orleans – TCAA sponsored 9 special sessions with 84 papers presented. Our open committee meeting was held on Tuesday, December 5, 2017 with approximately 90 in attendance.
Minneapolis – TCAA sponsored 6 special sessions with 50 papers presented. Our open committee meeting was held on Tuesday, May 8, 2018 with 73 in attendance.

The 174th ASA meeting was held in New Orleans, LA. The special sessions were “Wave Propagation in Complex Media: From Theory to Applications (Joint with SA and Vibration and PA)” organized by Guillaume Haiat and Pierre Belanger and “Ultrasound-Mediated Neuromodulation” organized by Parag Chitnis. The TPOM representatives for the meeting were Siddhartha Sikdar and Kang Kim.
The BATC meeting on Wednesday evening was also eventful, with 30 attendees. We discussed the results of the International Meeting survey where BA voted to have international meetings every 2–3 years over 4–5 years or 10 years. The consensus was to have international meetings every 4 years. We also discussed the Awareness of Acoustics outreach initiative and the need to have all ASA members update the exploresound.org database. In other topics, a BA technical initiative idea was proposed involving future educational workshops on ultrasound simulation packages. It was proposed that the first workshop would be on the FOCUS software and taught by Bob McGough. A technical initiative to fund this workshop was submitted to TC. The workshop was proposed for the Louisville meeting.

Biomedical Acoustics Technical Committee
This annual report reviews the efforts in Engineering Acoustics (EA) from the 173th June meeting in Boston, Massachusetts, to the 175th May meeting in Minneapolis, Minnesota. In that time span, the members and supporters of Engineering Acoustics produced 39 JASA articles in Engineering Acoustics.
The preference of the membership is for the EA committee meeting to be held at 4:30 p.m. on Tuesday if the program will allow. The program for Boston was too full but the EA meeting returned to 4:30 p.m. in subsequent meetings. The EA session on Sunday in Boston was chaired by Stephane Durand. Monday’s special sessions (2aEA, 2pEA) on “Ducts and Mufflers” were chaired by Mats A ° bom and David Herrin. The special sessions (3aEA,3pEA, 4aEAa) on Microelectromechanical Systems (MEMS) Acoustic Sensors was chaired by Vahid Naderyan, Kheirollah Sepahvand, and Robert D. White. Engineering Acoustics Topics (4aEAb) was chaired by Lane P. Miller and Hubert S. Hall. Thursday morning’s EA topics were chaired by Jordan Cheer and Andrew W. Avent. The afternoon session was chaired by Alexander L. Butler and Ferina Saati Khosroshahi. The best student presentation was given by Song Wang (5pEAa10) on “Generalized finite difference time domain simulation on acoustical moving boundary problems.”
The December 2017 session in New Orleans (174th meeting) had mixed weather, and a snowstorm closed the airport on Friday which caused delays for homeward bound travelers. The general topics in acoustics (1aEAa, 1aEAb, 1pEAa, 1pEAb, and 2pEA) were chaired by Kenneth Walsh. The special session on Thermophone Transduction (2aEA) was chaired by Thomas R. Howarth and Andrew R. Barnard. A contributed paper in this topic by Mahsa Asgarisabet was judged as best student paper. The EA meeting was held on Tuesday, December 5, at 4:30 p.m.
The main business was the election of a new EA Chair since the three-year term of Dr. K. M. Walsh ended with the Spring meeting. The election was conducted between the New Orleans meeting and the 175th meeting in Minneapolis. Dr. Mike Haberman was elected as EA Chair for the next three years.
The 175th meeting opened in Minneapolis on May 7, 2018. The first EA special session was on Miniature Acoustic Transducers, which was held on Tuesday and chaired by Vahid Naderyan. General Studies on Transducers was held on Wednesday and was chaired by K. M. Walsh.
The second special session held on Thursday was chaired by Dehua Huang on Advanced Transduction Technologies. The EA committee meeting took place at 4:30 on Tuesday. Mike Haberman was introduced as the newly elected EA Chair. The best student paper was by Athanasios Athanassiadis of MIT.
It has been an interesting three years and I have enjoyed working with everyone at ASA, in particular Elaine Moran. Her support and guidance were indispensable. I am looking forward to going to future meetings where I can relax and just enjoy the presentations. Thank you for the support over the last three years.
During 2017–2018 the Technical Committee on Musical Acoustics (TCMU) was chaired by Andrew Morrison. The representatives to the Society committees were: James P.

During 2016–17, the membership of the Technical Committee on Noise has been active in the Society and been honored to serve. Two members, Patricia Davies and Christopher Struck, were honored as Fellows in May 2018. Peggy Nelson was elected to serve as the vice president elect and was a co-chair of the Minneapolis meeting. Scott Sommerfeldt is serving as the vice president. Lily Wang is the current president of the Society. All have been active within TCNS through chairing sessions and helping to organize recent meetings.
TCNS has promoted the development of upcoming talent. This year marks the third year of the Leo and Gabriela Beranek Scholarship in Architectural Acoustics and Noise Control. This year’s recipient is Ms. Kieren Smith who is pursuing her Ph.D. in Architectural Engineering Acoustics at University of Nebraska-Lincoln. Kieren is a graduate of Brigham Young University in Physics with a Mathematics minor. In addition, this year is the second year for the Virginia and Frank Winker Memorial Scholarship for Graduate Study in Acoustics. This year’s recipient is Mr. Caleb Goates who is pursuing a Master of Science degree in Physics and Astronomy at Brigham Young University. Caleb is also a graduate of the Brigham Young University having earned his Bachelor of Science in Applied Physics. Coincidentally, we note that the advisors for these two scholars are Drs. Lily Wang and Scott Sommerfeldt for Keiren and Caleb, respectively. As the outgoing TCNS Chair, I would encourage faculty at all universities to encourage students to apply for these two scholarships. I, along with the members of the Beranek scholarship committee [Eric Reuter (Chair TCAA), Tony Hoover, Alex Case, Carl Rosenberg] and the Winker scholarship committee [Christopher Struck (ASA Standards Director), Eric Reuter (Chair TCAA), and Ken Walsh (Chair TCEA)] have been privileged to review the applications of the students.
TCNS has honored several Young Investigators for the excellent paper that they have presented at the New Orleans and Minneapolis meetings. In New Orleans, Christopher Jasinski presented a paper entitled “Acoustic excitation impact on aerodynamic drag measured in aeroacoustic liners.” Jay Bleifnick presented a paper entitled “Evaluating hospital soundscapes to improve patient experience.” In Minneapolis, three papers were honored for the Young Investigator awards. Simon Benacchio presented a paper entitled “Acoustical corrections to be used for improved inear noise dosimetry measurements.” Fabien Bonnet presented a paper entitled “Application of a registration method on magnetic resonance images to evaluate the displacement field of a human subject ear canal to various earplug insertions.” Yutong Xue presented a paper entitled “Fibrous material microstructure design for optimal structural damping.” Congratulations to each of these young investigators.
One of the new efforts undertaken by the Society and promoted by the TCNS is the International Noise Awareness Day. Brigitte Schulte-Fortkamp championed the outreach for the ASA and Lily Wang organized our participation on April 25. Lily Wang moderated an online Google Hangout discussion with Arlene Bronzaft, Bennett Brooks, William Murphy, Peggy Nelson, and Brigitte Schulte-Fortkamp. The teleconference was recorded and will be posted on the ASA’s YouTube channel.
The 174th meeting of the ASA was held in New Orleans with 6 TCNS-led sessions and 66 papers presented. David Woolworth and William Murphy served as the TPOM representatives. The 175th meeting of the ASA was held in Minneapolis. At this meeting, 54 papers were presented in six noise-led sessions. For the Boston Meeting, Peggy Nelson and William Murphy were the TPOM representatives. At both meetings, numerous other sessions were co-sponsored by TCNS.
Thanks to following people who have represented TCNS within the ASA during this time: Kirill Horoshenko and Brigitte Schulte-Fortkamp on the Medals and Awards Committee, Alex Case on the Membership Committee, John Weber on Student Council, Rich Peppin on ASACOS (Committee on Standards), and Christopher Struck, Standards Chair. For the Young Investigator Award, William Murphy coordinated both the New Orleans and Minneapolis meetings.

I completely updated the PPTC webpage (http://tcppasa.org/) in time for the Minneapolis meeting, and any suggestions, corrections, or additions should be submitted using the links on the pages. Over the coming year, the PPTC is already planning many special sessions (four for Victoria, BC and seven for Louisville) and will be continuing to reach out to our colleagues in Physiological Acoustics, clinical researchers, and educators in acoustics and hearing sciences, as well as those emerging scientists in all areas relevant to PPTC through special sessions and technical initiatives.
As Chair of PPTC, I welcome new technical initiatives, special sessions, and any other suggestions that will ensure our part of ASA is vibrant and growing for years to come. I charged the membership at the meeting in Minneapolis to be sure to nominate their deserving colleagues for medals and awards and to be made ASA Fellows. The diversity of PPTC and of ASA is our greatest strength and we must do everything we can to make sure that as wide array of personal backgrounds, areas of expertise, and perspectives as possible are represented and honored at our meetings and in our society.

Alexander Francis has also agreed to represent our TC on the ASA Panel on Public Policy. I also thank Sarah Ferguson, Kelly Berkson, and Emily Wang for taking detailed minutes at the Honolulu and Boston meetings. We appreciate the time and energy contributed by our TC members.
A special thanks to the TC members who will complete their term of service in June 2018.
Publications: Current Associate Editors for JASA are: Speech Production—E. Jacewicz, L. Koenig, and Z. Zhang; Speech Perception—D. Baskent, T. Bent, S. Ferguson, M. Sundara, and B. Tucker; Speech Processing—C. Espy-Wilson, J. Hansen, and M. Mandel. Associate Editors for JASA Express Letters are: Speech Production—A. Lofqvist; Speech Perception—M. Cooke and R. Smiljanic; Speech Processing and Communication Systems and Speech Perception—D. D. O’Shaughnessy. Kanae Nishi will be working with Cathi Rogers as AEs POMA for SC.
Kanae is replacing Peter Watson who has filled this role for 7 years. We thank Peter for his time and commitment to the POMA. Technical Program: Over the last three ASA meetings, the Speech TC organized a number of stimulating special sessions on diverse topics (summarized below). These sessions ran very smoothly and were well received by our members. Melissa Baese-Berk and Kristin van Engen were TPOS for the past two meetings. Our TC is grateful for the dedication and care of these individuals who ensure that SC program planning is in good hands. Our members have also embraced the live-streaming initiative. At the Fall 2017 (New Orleans) meeting we sponsored three special sessions: “Articulatory and Acoustic Characteristics of Nasalization,” organized by Liran Oren; “Teaching Phonetics and Speech Science in the New Millennium: Challenges and Opportunities,” organized by Ben Tucker and Cathy Rogers; “The Southern States: Social Factors and Language Variation,” organized by Wendy Herd and Irina Shport.
At the Spring 2018 (Minneapolis) we sponsored 3 Special Sessions: “South Asian Languages,” organized by Kelly Harper Berkson, Sameer Khan, Christina Esposito, and Indranil Dutta; “Adapting Methods and Models for Vocal Production Across Human and Non-human Primate Species,” organized by Mary Beckman, Ben Munson, and Michael Wilson; “Session in memory of James J. Jenkins,” organized by Kanae Nishi, Terry Gottfried, and Linda Polka.
Student poster competition: Thanks to the special efforts by Patrick Reidy and Chao Yang Lee we have some new tools that make organizing the poster competition more efficient. These tools help to identify judges from program, assign judges to posters, and gather judge’s scores and comments using an electronic form to automate the data compilation. Each meeting we pick two winners and also provide every student who is a valid candidate for the competition with some feedback from the judges of their poster. The energy poured into developing this process and the high volume of student entries and judges participating at each meeting demonstrates our strong commitment to high quality research and to the mentorship that this entails. The Fall 2017 (New Orleans) competition was organized by Charles Chang and Kelly Berkson; the Spring 2018 (Minneapolis) competition was organized by Kelly Berkson and Wendy Herd.
Awards: No awards were given in Speech Communication this year. The SC TC needs to put more energy into preparing nominations as our TC has a number of accomplished scientists who are very strong award candidates.
Membership: One new fellow in Speech Communication was selected this year: Tessa Bent. The SC TC also needs to put more energy into nominating fellows. There is no shortage of deserving candidates in our TC.
Stetson Scholarship: The Review Committee for 2018 included Jody Kreiman (Chair), Eric Hunter, Lori Leibold, Helen Hanson, and Peter Assmann. We thank them for their time and effort in reviewing the applications.
The Structural Acoustics and Vibration Technical Committee (SAVTC) had an effective and fruitful 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 2017–18 period beginning after the Spring 2017 ASA Boston meeting. During this period, Robert Koch completed his third year of the 2015–2018 first term as chair of the SAVTC. Early in 2018 an election was held and administered by the ASA where Robert Koch was re-elected as ASA SAVTC Chair for a second three-year term for the period 2018–2021. Robert is honored by the reelection and will work hard to try and deserve the vote of confidence. During this same period, the SAVTC’s own Brian Anderson and James Phillips were elected as the new Chairs of the Signal Processing and Noise Technical Committees, respectively. Congratulations to them both! The SAVTC extends its gratitude to the many SAVTC members and friends of SAV who actively participate as volunteer lead representatives for numerous ASA committee and editorial activities including, but certainly not limited to:
- Robert Koch (ASACOS);
- James Phillips (Medals and Awards);
- Robert Koch (Membership Committee);
- Brian Anderson (SAVTC Web page);
- Tyler “TJ” Flynn (Student Council);
- Matthew Kamrath (Education in Acoustics Committee);
- Ben Shafer (Student Paper Competition);
- Ben Shafer and Robert Koch (Technical Program Organizers);
- Brian Anderson (Coordinating Editor), Li Cheng, Karl Grosh, Nail
Gumerov, Nicole Kessissoglou, Kai Ming Li, Franck Sgard, Nickolas
Vlahopoulos, and Kuangcheng Wu (JASA Associate Editors for SAV);
- Greg McDaniel (JASA Express Associate Editor for SAV);
- Steve Shepard (POMA Editor).
Update: Just following the Spring 2018 ASA Minneapolis meeting, the current terms for Brian Anderson (SAVTC Coordinating Editor), Li Cheng, and Nail Gumerov ended on 30 June 2018 as JASA Associate Editors for SAV (Thanks to them all!). A search for a new SAVTC Coordinating Editor to succeed Brain Anderson is underway. At the 174th ASA meeting in New Orleans, Louisiana, SAVTC sponsored the following three special sessions and one General session of contributed papers with a total of 44 papers presented (16 invited, 28 contributed):
- “Acoustic Metamaterials”: Co-Chairs, Christina Naify and Michael Haberman;
- “Standards in Structural Acoustics and Vibration”: Chair, Benjamin Shafer (ASACOS Standards committee has agreed to co-sponsor the session);
- “SAV Applications of FEA, BEA, and SEA Computational Methods”: Co-chairs, James Phillips and Elizabeth Magliula;
- “General Topics in Structural Acoustics and Vibration”: Chair, Benjamin Shafer
The TPOM representative was Benjamin Shafer.
SAVTC had 19 papers entered in the Best Student and Young Presenter competition at the 174th ASA Meeting. Ben Shafer coordinated the competition and the winners were:
Stephanie G. Konarski, University of Texas at Austin, “Closed-cell hyperelastic elements with mechanical instabilities and structural negative stiffness”
Alyssa T. Liem, Boston University (returning as THIRD TIME finalist!), “Characterizing hysteretic materials in complex systems from vibration measurements”
During the New Orleans meeting, fellow SAVTC member Jerry Ginsberg held a formal book signing event for the recent completion and publication of his new two-volume book set titled “Acoustics—A Textbook for Engineers and Physicists” [Vol. I (Fundamentals) and Vol. II (Applications)]. Sincere congratulations to Jerry from his friends in the SAVTC and the ASA in general for this major and impressive accomplishment!
Also at the New Orleans meeting, the first two SAVTC sessions ever to be live-streamed occurred and appeared to go smoothly and successfully. Specifically, the two special sessions “Standards in Structural Acoustics and Vibration” (1aSA), and “Acoustic Metamaterials I and II” (2aSA/2pSA) were live-streamed in New Orleans.
At the ASA Minneapolis meeting, SAVTC sponsored the following three special sessions and one General session of contributed papers with a total of 43 papers presented (16 invited, 27 contributed):
- “Acoustic Metamaterials”: Co-Chairs, Christina Naify and Alexey Titovich;
- “Improving Education in Structural Acoustics and Vibration”: Co-Chairs, Brian E. Anderson and Scott D. Sommerfeldt;
- “Model Reduction for Structural Acoustics and Vibration”: Co-Chairs, Kuangcheng Wu and Hubert Hall;
- “General Topics in Structural Acoustics and Vibration”: Chair, Benjamin Shafer.
The TPOM representatives were Robert Koch and Benjamin Shafer.
The winners of the Best Student and Young Presenter competition (11 entrees), well-coordinated again by Ben Shafer, are still to-be-determined as of the date of this Annual Report. Winners will be notified soon once the final tallying has been made.
At ASA Minneapolis, the third SAVTC session ever was livestreamed (2pSA: “Improving Education in Structural Acoustics and Vibration” co-chaired by Brian E. Anderson and Scott D. Sommerfeldt). In addition, two Interdisciplinary (ID) special session papers presented by Robert Koch titled “Introduction to the Structural Acoustics Technical Committee” and “Hot Topics in Structural Acoustics and Vibration: Advances in Vibroacoustic Modeling and Novel Materials” were also live-streamed at the Minneapolis meeting. The live-streaming experience for all the above was mostly nonintrusive and largely positive.
The period 2017–2018 of this ASA SAVTC Annual Report represents the year (and two ASA meetings) just following the 2016–2017 year with two consecutive major joint ASA meetings in a row, the Honolulu and Boston meetings, both record setting in size and attendance. These two major events represented a significant challenge to the SAVTC (very successfully met it should be noted, along with all other ASA TC’s) in terms of volunteer time commitments, etc., it is noticed that the two meetings in this annual period had a slight drop in number of sessions planned. This dip is quite normal and completely understandable following the extra burden carried in 2016–17. It is observed that there is already an increase in SAV planned sessions and TC activities in upcoming 2018 ASA meetings and beyond.
A recent priority of the SAVTC Chair has been to increase the numberof new members in the committee and to try and get younger as a committee as well. This is primarily in response to the declining volunteering and meeting attendance of a number of the more senior members of the committee who are now quite understandably drawing down their society activities after decades of contribution at the highest possible levels in the Society. As a result of this thrust, four new SAVTC members were officially added in January of 2018—congratulations and welcome aboard to new SAVTC members Kathryn Matlack, Alexey Titovich, Pei-Tai Chen, and Anthony Bonomo. In addition, another four meeting attendees expressed interest at the ASA Minneapolis meeting and will now be considered and, if deemed suitable, added to the SAV technical committee membership role in the January 2019 new member request cycle.
