Fighting #Hearing Loss From the Crowd’s Roar Silent, cumulative loss from the effect of loud sounds over a lifetime

Ears are deceptive. Even if they seem to recover from the muffling, ringing and fullness after a rousing game, they don’t really recover. It’s not just the tiny sensory cells in the cochlea that are damaged by noise, Dr. Liberman said, but also the nerve fibers between the ears and the brain that degrade over time.
Too much noise causes not just partial deafness, which usually starts with trouble hearing in background noise, but an assortment of poorly-understood auditory abnormalities. These include tinnitus, or ringing in the ear, and hyperacusis, a sensitivity or intolerance to sound, sometimes with ear pain.
