The purpose of this study was to determine the effect(s) of tinnitus maskers and tinnitus instruments on speech discrimination utilizing a population of subjects who currently have tinnitus and are presently wearing these devices. The hypothesis which guided this investigation states that there is no difference between discrimination scores with and without tinnitus maskers. In an attempt to test this hypothesis, speech discrimination scores were obtained from 26 listeners both in quiet and in the presence of cafeteria noise, with and without use of their tinnitus maskers.
