In a crowded restaurant, the sounds of conversations bounce off walls, creating background noise. Each individual wants to be heard, so they end up talking a little bit louder, which increases the overall din. Eventually – barring an interruption – the system gets loud enough to reach the limit of the human voice. Braxton Boren will discuss this cycle, called the Lombard effect, and how it can be disrupted in his presentation, “A game theory model of the Lombard effect in public spaces.”
A newly published study of orb-weaving spiders — has yielded some extraordinary results: The spiders are using their webs as extended auditory arrays to capture sounds, possibly giving spiders advanced warning of incoming prey or predators.
Among the first cases to be heard by the U.S. Supreme Court for the October 2022 term will be Sackett v. EPA, No. 24-454 (2022). At stake is the definition of “waters of the United States” and the area of…
In The Journal of the Acoustical Society of America, scientists explore how digital health solutions can expand audiology services in clinical and research settings. Audiology assessment via telehealth would allow patients to access care while a specialist is located hundreds of miles away and, as a research tool, telehealth would allow for more representative and decentralized data on hearing, without compromising results. The team is currently scaling up several studies they conducted in rural areas of Alaska; their mission is to close the gap on hearing health disparities.
More than 55 million people worldwide are believed to be living with dementia, according to the World Health Organization. Ronald Petersen, M.D., a neurologist and director of Mayo Clinic’s Alzheimer’s Disease Research Center, says you can’t prevent dementia, but you can reduce your risk.
In her presentation, “Aging effects on listening effort in cochlear-implant users,” Kristina DeRoy Milvae will discuss the results of two experiments that examined impacts on listening effort. The session will take place May 24 at 12:50 p.m. Eastern U.S. at the 182nd Meeting of the Acoustical Society of America at the Sheraton Denver Downtown Hotel.
Many Covid-19 patients have reported symptoms affecting the ears, including hearing loss and tinnitus. Dizziness and balance problems can also occur, suggesting that the SARS-CoV-2 virus may be able to infect the inner ear.
“We are excited to open up this new service to our growing community,” said William DiStanislao, interim president, chief hospital executive, Raritan Bay Medical Center Old Bridge. “Our certified audiologist will work closely with our medical director to interpret findings and recommend appropriate treatment.”
Hearing conservation programs and policies aim to protect workers from noise-induced hearing loss, but it remains unclear whether stress reactions caused by noise exposure might also lead to other negative health outcomes. In The Journal of the Acoustical Society of America, researchers describe how data from the Canadian Health Measures Survey do not support an association between loud noise exposure and changes in biomarkers for cardiovascular disease or outcomes.
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.
Press conferences at the 180th ASA Meeting will cover the latest in acoustical research during the Acoustics in Focus meeting. The virtual press conferences will take place each day of the meeting and offer reporters and outlets the opportunity to hear key presenters talk about their research. To ensure the safety of attendees, volunteers, and ASA staff, Acoustics in Focus will be hosted entirely online.
From the impact of COVID-19 on parents, to speech differences between English- and Spanish-learners, and advanced ear surgery techniques, University of Miami Miller School of Medicine hearing professionals presented their latest studies at CI2021, the annual conference of the American Cochlear Implant (ACI) Alliance, from April 28 to May 1.
Researchers will be dedicated to battling hearing loss resulting from numerous causes. They will tackle hearing loss in children whose hearing is compromised by antibiotics or other medical treatments, to persons suffering hearing loss in the wake of cancer therapies, those who suffer deafness due to such infections as meningitis, through to natural hearing loss caused by aging.
Neandertals — the closest ancestor to modern humans — possessed the ability to perceive and produce human speech, according to a new study published by an international multidisciplinary team of researchers including Binghamton University anthropology professor Rolf Quam and graduate student Alex Velez.
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.
Several acoustic studies have shown that the position of your eyes determines where your visual spatial attention is directed, which automatically influences your auditory spatial attention. Researchers are currently exploring its impact on speech intelligibility. During the 179th ASA Meeting, Virginia Best will describe her work to determine whether there is a measurable effect of eye position within cocktail party listening situations.
As part of the 179th ASA Meeting, 25 sound scientists summarize their innovative research into 300-500 words for a general audience and provide helpful video, photos, and audio. These lay language papers are written for everyone, not just the scientific community. Acousticians are doing important work to make hospitals quieter, map the global seafloor, translate musical notes into emotion, and understand how the human voice changes with age.
People’s exposure to environmental noise dropped nearly in half during the early months of the coronavirus pandemic, according to University of Michigan researchers who analyzed data from the Apple Hearing Study.
According to a study by University of Miami researchers published in the Journal of Communication in Healthcare, there are no consistently applied best practices in how to educate patients about what tinnitus is and options for management.
Scientists have mapped and simulated filaments in the inner ear at the atomic level, a discovery that shed lights on how the inner ear works and that could help researchers learn more about how and why people lose the ability to hear.
Using a device that could be built with a dollar’s worth of open-source parts and a 3D-printed case, researchers want to help the hundreds of millions of older people worldwide who can’t afford existing hearing aids to address their age-related hearing loss.

Scientists at St. Jude Children’s Research Hospital are studying how hearing loss can affect the neurocognitive abilities of childhood cancer survivors. Findings show that survivors with severe hearing loss are at a significant increased risk for neurocognitive deficits, independent of what type of therapy they receive.
USC Stem Cell scientists have pioneered a simpler way to generate the sensory cells of the inner ear. The study was published in the journal eLife.
New research is shedding light on the biological architecture that lets us hear – and on a genetic disorder that causes both deafness and blindness.
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.
Mount Sinai research highlights the need for more hearing checks among groups at high risk for falls
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.
Popping your ears by yawning or chewing gum can help alleviate pressure. But if that doesn’t help, a more permanent solution might be Eustachian tube dilation.
Animal models can serve as gateways for understanding many human communication disorders, but a new study from the University at Buffalo suggests that the established practice of socially isolating mice for such purposes might actually make them poor research models for humans, and a simple shift to a more realistic social environment could greatly improve the utility of the future studies.
Researchers from Massachusetts Eye and Ear, Harvard Medical School and a team of EPFL researchers have developed a conformable electrode implant that will allow people with a dysfunctional inner ear to hear again. This new technology would improve existing auditory brainstem implants, which have a number of shortcomings.
