Scientists Discover Biological Mechanism of Noise-Induced Hearing Loss
The study showed that noise-induced hearing loss stems from cellular damage in the inner ear associated with excess free-floating zinc.

A jury in Tallahassee, Florida awarded a plaintiff in the 3M lawsuit $22.5 million, the largest amount yet in a class action lawsuit against the Maplewood, Minn-based company, according to the Star Tribune. The lawsuit alleges that plaintiffs suffered hearing damage as a result of undisclosed design flaws in 3M's dual-ended Combat Arms Earplugs, Version 2 (CAEv2).
A single loud blast or explosion that lasts for less than 1 second can cause permanent hearing loss right away. This noise, called impulse noise or impact noise, can come from sources such as fireworks or gunfire.
In the company’s announcement, Frequency Therapeutics provides updates on data from its recent FX-322 Clinical Readouts, including new information from a Phase 1b study in presbycusis, and further clarifies acquired sensorineural hearing loss target populations and future study design. The company anticipates initiating a new FX-322 Phase 2 Study in H2 2021.

Read MoreNew research announced by the Hearing Industries Association (HIA) reveals that 4 out of 5 Americans consider hearing loss serious, but ignoring the problem is more common than you may think. Fewer than 16% of adults ages 20-69 who need a hearing aid use one. That number almost doubles to 30% for adults over age 70 who need a hearing aid but don’t use one, according to the National Institute on Deafness and Other Communication Disorders (NIDCD).

Read MoreLRADs 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.
Read MoreResearchers examined 120 inner ears collected at autopsy. They used multivariable statistical regression to compare data on the survival of hair cells, nerve fibers, and the stria vascularis with the patients’ audiograms to uncover the main predictor of the hearing loss in this aging population. They found that the degree and location of hair cell death predicted the severity and pattern of the hearing loss, while stria vascularis damage did not.
