Hi Avery,

Not yet, but I now have two docimeters that measure the noise dose a person 
is exposed to over a 24 hour period.

Last weekend I measured the exposure that Ken Medema was receiving at the 
Baldwin SD-10 during his concert at Mt. Hermon Christian Conference Center.  
The 2 hour concert gave him 15% of an allowable noise dose at 80dB, 13% at 
90dB. There were no peaks over 115dB.  Sitting in the 5th row center, I 
received only 5% at 80dB and 1% at 90dB.  But it sure sounded loud to me and 
I wore my earplugs for comfort.

I am hoping a friend who tunes at the university here will wear a docimeter 
for me soon.

I'm pushing for carpet in the piano major practice rooms and just
wanted some "ammunition"! :-)
