Subject: Re: Tinnitus and a dip in the audiogram From: Tom Brennan <g_brennantg@xxxxxxxx> Date: Mon, 10 Sep 2012 08:49:18 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>I sometimes also use narrow band masking noise when testing tinnitus patients. Another issue is that the audiogram uses discrete frequencies which are supposed to be representative of the auditory system's functioning. I have particularly found this not to be necessarily true with tinnitus and suggest using a sweep audiogram of some sort if you can get the proper equipment. It provides much better information. You might also find looking at the difference between 220 and 660 Hz probe tones as providing useful information particularly when used in extended reflex testing.
