[Trombone-l] Sound & Hearing Loss

[Jeff Albert]

I forgot to post this when all of the SPL talk was happening.  In the  
late 90's i had a friend in graduate school studying audiology.  For  
one of her projects she did an experiment, where she took SPL  
readings from inside my ear canal while I played.  The measurements  
were done by a device that wrapped around my outer ear, and held a  
filament that dangled in the entrance to my ear canal.  We tested  
pp,p , mp, mf, f , and ff on low middle and higher Bb.  As I recall  
the higher octaves registered consistently higher readings than the  
same dynamic at a lower octave.  I don't remember all of the data,  
but I do remember that middle Bb at forte was about 100 db in my  
ear.  That's me alone, no other noise.
