OSTON — Baby boomers grew up with music blasting from dorm room turntables, car stereos, and arenas where the sound of a band at full throttle could rival the roar of a jet engine. Volume became an act of generational defiance. As rocker Ted Nugent put it: “If it’s too loud, you’re too old.”
Turns out, it was too loud. Millions of boomers are now grappling with hearing loss — some of it caused by turning the volume to 11 — prompting companies to develop treatments that improve upon the expensive and often limited-value hearing aids and surgical implants that have been around for decades.
