Researchers at the University of Connecticut found increase levels of a protein called prestin in blood after exposure to loud noise. The prestin comes from the hair cells in the cochlea when they are damaged by noise. If this research holds up, it can help researchers study drugs that might prevent hearing loss from noise exposure.

Of course, one doesn’t need a new protein or a drug to prevent hearing loss from noise exposure.

Just avoid loud noise.

If the ambient noise level is high enough that you have to strain to speak or to be heard when having a normal conversation, the ambient noise is above 75 A-weighted decibels, and your hearing is being damaged.

Remember: if it sounds, too loud, it IS too loud!

Hearing test developed to detect hidden hearing loss

UConn School of Medicine researchers develop first hidden hearing loss hearing test. EurekAlert! reports that “[t]wo researchers at UConn School of Medicine have developed a new hearing test that can identify hearing loss or deficits in some individuals considered to have normal or near-normal hearing in traditional tests.”  Leslie R. Bernstein, professor of neuroscience and surgery at UConn, who conducted the study with Constantine Trahiotis, emeritus professor of neuroscience and surgery, explained the importance of the new test by noting that “acquired hearing loss from excessive noise exposure has long been known to produce significant, and sometimes debilitating, hearing deficits.”  EurekAlert! writes that the “new research suggests that hearing loss may be even more widespread than was once thought,” adding that with this new test, there now is a “validated technique to identify ‘hidden’ hearing deficits that would likely go undetected with traditional audiograms.”
