Update Noise Regulations to Protect Seals, Porpoises
In The Journal of the Acoustical Society of America, scientists in Denmark review recent experiments and find noise regulations may need to be changed to protect porpoises, seals, and other sea-dwelling mammals. Current guidance for seals and porpoises is based on few measurements in a limited frequency range; the guidance is still valid for these frequencies, but investigators found substantial deviations in recent studies of the impact of low frequency noise on seals and high frequency noise on porpoises.
Making Racetrack Noise Bearable with Physics #ASA182
Raceways can produce noise from many kinds of vehicles, such as race cars, street race cars, racing motorcycles, go-karts, monster trucks, and cheering spectators. During the 182nd ASA Meeting, Bonnie Schnitta, from SoundSense LLC, will discuss her efforts to reduce the noise in a Michigan neighborhood from a nearby raceway. She and her team examined several different types of barriers, including berms, acoustic barriers, or dense foliage, to block that noise from reaching surrounding houses and businesses.

Pandemic Quarantine Acoustically Contributes to Mental, Physical Health Degradation
The prolonged impact of the COVID-19 pandemic created widespread lockdown fatigue and increased social tension in multiunit housing, but small improvements in quality-of-life routines may help people cope. During the 180th ASA Meeting, Braxton Boren from American University will discuss noise prevention techniques and the use of alterative acoustic stimulation to help those who find themselves in pandemic-related lockdowns. The session, “The Soundscape of Quarantine,” will take place Wednesday, June 9.
Measuring Sound Diversity of Quietness
The world is filled with myriad sounds that can overwhelm a person with relentless acoustics. Noise is so prevalent in everyday life that the concept and achievement of comfortable quiet is hard to define. During the 180th ASA Meeting, Aggelos Tsaligopoulos from the University of the Aegean will describe how quiet could be measured in the hopes of better understanding its impact on people. The session, “Towards a new understanding of the concept of quietness,” will take place Wednesday, June 9.

How Loud Is Too Loud? Identifying Noise Levels That Deter Older Restaurant Patrons
As restaurants get noisier, the increasing noise levels could deter older patrons, especially those with mild to severe hearing loss. Researchers from the University of Illinois at Urbana-Champaign will discuss their work on investigating acceptable noise levels that won’t cause restaurant visitors to stay away from certain establishments. Identifying acceptable noise levels helps establish truly “age-friendly” communities. The session will take place as part of the 179th ASA Meeting.
