The Audiologist Informer

Small molecules in the blood necessary for cell metabolism, called metabolites, were analyzed in a group of about 6,500 women, including about 500 who had daily persistent tinnitus. The researchers found three metabolites that were positively associated and two that were inversely associated with persistent tinnitus. This suggests further studies involving metabolites may help improve our understanding of tinnitus and identify biomarkers and therapeutic targets for it.

Correction: Yesterday's AI e-newsletter incorrectly stated the day for Part 3 of the Phonak & ADA-sponsored "OTC Hearing Aid Mega Series" featuring audiologist Dr. Michael Valente. Here is the link to sign up to view Part 3, as well as Parts 1 and 2 which were presented by Brent Edwards and Larry Humes.

Researchers from Japan have developed a method to estimate the direction of sound signals in 3D space using monaural cues that could help simplify sound surveillance techniques and enhance function in hearing aids.

Using a new computational approach, an international research team analyzed large genetic datasets of patient groups with rare diseases to discover the previously unknown genetic causes of three rare conditions: primary lymphedema, thoracic aortic aneurysm disease, and congenital deafness.
