‘Molecular Handshake’ Between Tip Links in Ear Essential to Hearing, Balance

We hear sounds in part because tiny filaments inside our inner ears help convert voices, music, and noises into electrical signals that are sent to our brains for processing. Now, scientists have mapped and simulated those filaments 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.

LRADs, Trumpets, and Loudspeakers

LRADs are loudspeaker systems on steroids and are easily capable of generating outputs on the order of 120 dBA at 10 meters. Although we don’t have very good models for noise exposure over 115 dBA, we do know that levels of 120 dBA (with peaks being up to 15 dB higher) can create acoustic trauma.

Hearing Loss, Cleft Conditions, and Craniofacial Abnormalities

Children with cleft lip and/or cleft palate—the most common birth defect in the United States—present unique audiologic challenges that include a high incidence of otitis media with effusion (OME). Recently, the MED-EL ADHEAR system has opened up new options for these patients. Five case studies are presented here showing how this new system represents an innovative, non-surgical therapeutic option for children who are born with cleft palate.

Full Bandwidth Streamed Audio with an Open-fit: Is It Possible?

With the proliferation of smartphone usage amongst hearing aid users, good sound quality during streaming is no longer a ‘desire’ but a ‘need.’ Unlike conventional acoustic hearing aids, the Earlens Contact Hearing Aid’s unique mechanism of action allows for the provision of low-frequency output for streamed sources while maintaining a widely vented fitting. Using an industry-wide standard method for evaluation of sound quality, subjective judgments of streamed audio quality of the Earlens compared with other MFi-capable acoustic hearing aids reveals that the Earlens Contact Hearing Aid offers the best streamed audio sound quality for both speech and music.
