The ringing starts after every gig. I pretend it's normal. At 100 dB, damage starts after 15 minutes. A gig lasts 3 hours. I see the older musicians. Permanent tinnitus. "If only I'd known," they all say. I tried foam plugs. They block everything. Can't hear the band. Can't hit notes. Then I found out: foam can actually make tinnitus worse. Complete seal amplifies body sounds. Porous material pushes earwax in. Selective filtering is different. Volume down. Sound stays the same. No complete seal. No pressure on the ear canal. 98% of surveyed users noticed a decrease in their tinnitus symptoms. The ringing after the gig? Gone. One musician wrote: "The DIFFERENCE in my post-gig pain is phenomenal." ISO 4869 certified. £26.95. My ears are my instrument. They're worth it.
Not enough history yet to show a trend.
