Cochlear implants should be recommended for adults more often

An international group of hearing specialists has released a new set of recommendations emphasizing that cochlear implants should be offered to adults who have moderate to severe or worse hearing loss much more often than is the current practice. The group hopes the recommendations help increase usage of such devices, potentially improving hearing and quality of life for millions worldwide.

Study uncovers hair cell loss as underlying cause of age-related hearing loss

In a new study of human ear tissues, hearing scientists have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into the electrical signals that are relayed to the brain by the auditory nerve. Their research challenges the prevailing view of the last 60 years that age-related hearing loss is mainly driven by damage to the stria vascularis, the cellular “battery” that powers the hair cell’s mechanical-to-electrical signal conversion.
