Earlier this summer, I attended the 21st International Congress on Acoustics, which was held from June 2 through 7 in Montreal. Hosted by the Acoustical Society of America (ASA) and the Canadian Acoustical Association (CAA) under the auspices of the International Commission for Acoustics (ICA), the program included early morning plenary lectures, presentations of technical papers, poster sessions, an exposition featuring acoustical products and services, technical meetings, activities for students, and social gatherings. ICA reported 2,300 registered attendees including students and professionals, and more than 1,600 technical papers were presented.
I presented a research paper in a poster session that introduced technical and statistical information about remote keyless entry alert sounds in the US and Canada. Using available industry data over a seven-year span, my presentation featured three case studies of people who addressed the noise that affected their lives. I attended around thirty technical presentations and poster sessions, networking events, a technical meeting, and the vendor exposition.
A broad range of disciplines were reflected in the technical programs, some of which included acoustical oceanography, animal bioacoustics, architectural, biomedical, engineering, musical, physical, psychological, and physiological acoustics, signal processing, speech communication, structural acoustics and vibration, underwater acoustics, and noise.
I attended as many sessions as I could. A session might include four to eight presentations, and each presentation lasts twenty minutes, with the last five minutes saved for questions and answers. It is helpful to attend sessions across a broad range to become more familiar with the
field of acoustics generally. However, I wanted to attend every session on vehicle noise, particularly those focusing on warning signals for electric and hybrid vehicles, and backup beeping. The papers I enjoyed most were What will be the influence of e-mobility on soundscape? and Detectability and annoyance of warning sounds for electric vehicles. I also enjoyed the papers Comparison of discomfort caused by two kinds of backup beeping, Noise in hospitals as a strain for the medical staff, Noise stress for patients in hospitals, Characterizing the soundscape of tranquil urban spaces, and If a tree falls in a forest, can you hear it? as well as papers from the session “Urban Noise and Modeling”, including The internet and sound observatories, and Urban traffic noise assessment by combining measurement and model results. Other presentations related to noise included case studies of acoustical challenges and solutions.
All of the papers above can be found online and downloaded in PDF format. The meeting proceedings have been published as Volume 19 of POMA (Proceedings of Meetings on Acoustics), and can be accessed from this website
Papers on noise can be found here. All web pages have a search function.
The 22nd International Congress on Acoustics is scheduled to take place in Buenos Aires, Argentina, from September 5 through 9 in 2016, and will be hosted by the Ibero-American Federation of Acoustic (FIA), the Argentinean Association of Acoustics (AdAA) in cooperation with the Chilean Acoustics Society (SOCHA) under the auspices of the ICA.
