While I was having the audiogram which went along with the fitting of my 
musicians plugs, I mentioned the problem of having to loosen or remove 
storebought rubber earplugs to hear the top octave.  The audiologist 
produced an attenuation chart for the beasties which showed that, while 
rated for 12-15dB, that rating is for the 500-1000Hz range.  In the 
3000-4000Hz range [top octave], however,  they have about a 25dB 
attenuation.  This, coupled with the piano being weaker in that range, made 
me get the audiogram in the first place.

I compare the 15dB flat attenuation plugs to wearing darkglasses at the 
beach on a sunny day. You definitely can hear better when you eliminate the 
overload.
