Acoustics researchers at Aalto University, in collaboration with professional monitoring loudspeaker manufacturer Genelec, have investigated just how small of a variation in sound delay the human ear can detect in the most sensitive frequency range for hearing. People normally hear sound in the range of 20 and 20,000 hertz.
Evidence suggests auditory and vestibular effects should be added to the growing list of physiological impacts of COVID-19. During the 180th Meeting, Colleen Le Prell from the University of Texas at Dallas will talk about hearing and balance disorders associated with coronavirus infection and how pandemic-related stress and anxiety may aggravate tinnitus symptoms. Her presentation, “Hearing disorders secondary to infection with SARS-CoV-2,” will take place Thursday, June 10.
As more people are taking advantage of music on the go, personal audio systems are pumping up the volume to the detriment of the listener’s hearing. During the 180th ASA Meeting, Daniel Fink from The Quiet Coalition and Jan Mayes will talk about current research into personal audio system usage and the need for public health hearing conservation policies. Their session, “Personal audio system use can harm auditory health,” will take place Thursday, June 10.
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.
In the battle between hunter and hunted, sound plays an integral part in success or failure. In the case of bats vs. moths, the insects are using acoustics against their winged foes. During the 180th ASA Meeting, Thomas Neil from the University of Bristol will discuss how moth wings have evolved in composition and structure to help them create anti-bat defenses. The session, “Moth wings are acoustic metamaterials,” will take place Wednesday, June 9.
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.

Reporters are invited to attend the meeting at no cost and participate in a series of virtual press conferences featuring a selection of newsworthy research.
Scientists have yet to answer the age-old question of whether or how sound shapes the minds of fetuses in the womb, and expectant mothers often wonder about the benefits of such activities as playing music during pregnancy. Now, in experiments in newborn mice, scientists at Johns Hopkins report that sounds appear to change “wiring” patterns in areas of the brain that process sound earlier than scientists assumed and even before the ear canal opens.
A lemony scent and light sounds could change the way you feel about yourself. Previously, researchers have shown that visual and tactile stimulation can change a person’s perception of their own body weight. Research being presented by Giada Brianza at the 179th ASA Meeting, has found our hearing and sense of smell can also change how we feel about our self-image, which could help improve healthy behaviors.
Listeners can extract a lot of information about a person from their acoustic speech signal. During the 179th ASA Meeting, Dec. 7-10, Tessa Bent, Emerson Wolff, and Jennifer Lentz will describe their study in which listeners were told to categorize 144 unique audio clips of monolingual English talkers into Midland, New York City, and Southern U.S. dialect regions, and Asian American, Black/African American, or white speakers.
With each atom assigned a tonal signature based on its spectral signature, music can be a powerful tool for helping students understand atomic structure. Jill Linz is working toward synthesizing unique tones for each element to create an acoustic version of the periodic table. She will discuss her progress and the potential applications of the project at the 179th ASA Meeting, Dec. 7-10.
What if a commercial audio speaker could function like an autozoom projector does for light, and you could deliver the sound people want where they want it? Chinmay Rajguru, from the University of Sussex, will discuss his research team’s work creating a sound projector that can deliver spatial sound at a distance by forming a beam of audible sound at the 179th Meeting of the Acoustical Society of America, Dec. 7-10.
Using an imitation “ear” modeled on the organs that mosquitos use to hear, researchers have identified a mosquito’s species and sex using sound — just like mosquitos do themselves. The researchers hope this bioinspired detector could someday be used in the field to save lives by aiding in more selective pesticide use and possibly preventing mosquitos from mating. A presentation of the new research will be given as part of the 179th ASA Meeting.
Press conferences at the 179th Meeting of the Acoustical Society of American will cover the latest in acoustical research, from the impact of face masks to the beating of mosquito wings, and will be held virtually Dec. 9-11.

All events are open to the public, and admission is free.
Researchers at McMaster University who study how the brain processes sound have discovered the common practice of using artificial tones in perception experiments could mean scientists are overlooking important and interesting discoveries in the field of brain research
Ultrasound is probably most associated with a parent’s first glimpse of a baby in the womb. However, a new video from the Acoustical Society of America showcases the technology’s abilities to do more than show images of our insides. This video is the second in a series celebrating the International Year of Sound.
The Acoustical Society of America is calling on U.S. students to submit acoustics-related art and lyrics as part of the International Year of Sound 2020 celebration. K-12 students across the U.S. can participate in an international competition for primary, middle and secondary students from all over the world. It is also an opportunity to include an element of STEM education for so many students in need of enriching curriculum while being away from school due to coronavirus concerns.
Need to reduce high-pitched noises? Science may have an answer. In a new study, theoretical physicists report that materials made from tapered chains of spherical beads could help dampen sounds that lie at the upper range of human hearing or just beyond.
As harmful effects of noise are becoming more widely known, popular internet websites are increasingly being used as resources of information. For the International Year of Sound 2020 (#IYS2020), the Acoustical Society of America and the National Institute for Occupational Safety and Health, part of the CDC, took the lead in designing the online event Wiki4YearOfSound2020. The event will facilitate the improvement of Wikipedia content in topics related to acoustics, communication, music, noise and soundscapes.
