WASHINGTON, October 26, 2021 — Seeing a person’s face as we are talking to them greatly improves our ability to understand their speech. While previous studies indicate that the timing of words-to-mouth movements across the senses is critical to this audio-visual speech benefit, whether it also depends on…click to read more

WASHINGTON, August 31, 2021 — As electronic devices decrease in size, their component parts, like speakers, need to shrink as well. In JASA Express Letters, published by the Acoustical Society of America through AIP Publishing, researchers from Northwestern Polytechnical University in China and the University of Quebec developed three designs for compact speaker systems that control the…click here to read more.

Examining Correlation Between Occupational Noise, Heart Disease

WASHINGTON, August 10, 2021 — Occupational settings can involve exposure to loud noise, a known and preventable contributor to hearing loss. 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…click to read more
