This study shows that each type of medical mask essentially functions as a low-pass acoustic filter for speech, attenuating the high frequencies (2000-7000 Hz) spoken by the wearer by 3 to 4 dB for a simple medical mask and close to 12 dB for the N95 masks. In the era of Covid-19, Alexander Goldin, Barbara Weinstein, and Nimrod Shiman also explain how some of these problems might be overcome.
Chester Pirzanski, a long-time expert in earmold impression and manufacturing, proposes a new invention and automated process for designing custom hearing aid shells and earmolds from digitized ear impressions.
A new approach, published in “Cell Reports,” to regenerate inner ear sensory hair cells is said to lay the groundwork for treating chronic noise-induced hearing loss by the company, Frequency Therapeutics, and its co-founders who are drawing on research from Brigham and Women's Hospital (BWH), Harvard Medical School, Mass Eye and Ear Infirmary, and MIT. The program is expected to progress to into human clinical trials within the next 18 months.
