I've never seen scientific studies on damage from the typical sound pressure level of tuning pianos, but I've met a bunch of older tuners who had lost it. I've been using ER15's for many years and my hearing has stayed very good. Now if I could just do something about the damage done to my hands by cranking on that tuning lever all these years! dp David M.

I was surprised to learn that anyone believes that normal tuning would generate decibels anywhere close to ear-damaging levels. My understanding is that the "average" person can safely tolerate eight hours of continous 85 db. I'd guess the decibels normally generated by a piano tuning would be around 45 - 65 db, unless one is tuning the piano Jerry Lewis style :). I'm wondering what your basis would be for believing that tuning represents a threat to hearing (or does it simply seem more comfortable to you to wear earplug/filters?). Is it personal experience, or are you aware of scientific studies that confirm this possibility (I'm not aware of any, but that doesn't mean they don't exist)?
