Minneapolis Meeting Streamed Sessions

News and Announcements


Viewing Minneapolis Meeting Streamed Sessions


The Acoustical Society of America (ASA) once again facilitated remote participation in some technical sessions recently held at the ASA meeting in Minneapolis (7-11 May 2018). A number of papers in the special sessions listed below were broadcast in real-time over the internet using GoToWebinar.

Recordings of certain talks are now available for delayed viewing through 4 July 2018, if successfully captured and agreed upon by the authors.

ASA is offering this service specifically for members who were unable to attend the sessions in person, thereby broadening access to meeting content. During this piloting phase, there is no cost to ASA members.  Please note that photography, audio, and video recordings of content from ASA sessions are strictly prohibited, whether in person or over the internet.

Many thanks to all of you who have participated and given us your feedback on the initiative.  We have now broadcast content from six ASA meetings in a row, and are in the process of editing a number of the recorded talks and posting them to the ASA YouTube channel.  Please subscribe now to the ASA YouTube channel to be notified when new material is added.

We want to thank the members of the live stream subcommittee for their work in moving this initiative forward: Lily Wang (chair), Ken Bader, Anna Diedesch, Judy Dubno, Josh Gladden, Andrew Morrison, Himanshu Shekhar, and Anand Swaminathan.  Many thanks also to Anna Catton and Kieren Smith for coordinating the effort onsite at the last two meetings.

Acoustic Group – Staff-Level Engineer/Scientist

Epsilon Associates

Location: Maynard, MA


Epsilon Associates, a highly regarded mid-size engineering and environmental consulting firm based in Maynard, MA, is seeking a full-time staff-level engineer or scientist to work as part of the Epsilon team on a wide range of environmental licensing, permitting and compliance projects.  This position will encompass work primarily in the Acoustics Group.

In the Acoustics Group, the successful candidate will assist with community sound level measurement programs, meteorological data collection, data analysis, shadow flicker analyses from wind turbines, modeling, and report preparation.  This position requires regular field work as well as frequent overnight, out-of-state travel.

The ideal candidate will have:

1)     0-3 years of experience in a consulting environment;
