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. -- eliot Email to AUDITORY should now be sent to AUDITORY(at)lists.mcgill.ca LISTSERV commands should be sent to listserv(at)lists.mcgill.ca Information is available on the WEB at http://www.mcgill.ca/cc/listserv
