WASHINGTON, August 22, 2023 – Millions of people around the world experience some form of hearing loss, resulting in negative impacts to their health and quality of life. Treatments exist in the form of hearing aids and cochlear implants, but these assistive devices cannot replace the full functionality of human hearing and remain inaccessible for most people. Auditory experiences, such as speech and music…click to read more

WASHINGTON, April 25, 2023 – A general rule of music production involves mixing various soundtracks so the lead singer’s voice is in the foreground. But it is unclear how such track mixing – and closely related lyric intelligibility – has changed over the years.

WASHINGTON, March 21, 2023 – Only humans have the ability to use speech. Remarkably, this communication is understandable across accent, social background, and anatomy despite a wide variety of ways to produce the necessary sounds. In JASA, published on behalf of the Acoustical Society of America by AIP Publishing, researchers from…click to read more

WASHINGTON, Feb. 14, 2023 – When the Artemis 1 mission was launched by NASA’s Space Launch System, SLS, in November, it became the world’s most powerful rocket, exceeding the thrust of the previous record holder, Saturn 5, by 13%. With liftoff came a loud roar heard miles away. In JASA Express Letters, published on behalf of the Acoustical Society of America by AIP Publishing, researchers from Brigham Young University and Rollins College in Florida reported…click to read more

WASHINGTON, Nov. 1, 2022 – When two musical notes are played simultaneously, the human ear can perceive weak additional tones called combination tones. These subjective tones result from the nonlinearity of the inner ear and are attributed to the amplification mechanism of the cochlea. Subjective tones are perceived with…click to read more
