Dear Andy,

the experience I described involved the numbing of CERTAIN ISOLATED frequencies
at the higher end of the spectrum but not all frequencies. The music I was
hearing was in fact localized to a few specific frequencies. (I say frequencies
because the sound was produced with simple electronic waves.) My voice (after
the music was over)  seemed to me be be internally filtered -- I was not having difficulty
understanding speech and I was not aware that my hearing was generally impaired. The
effect wore off in a few minutes. My hearing is excellent.
