Abstract: This study aims to broaden the present understanding of the differences in cortical responses that may underlie the tendency of some people to perceive tinnitus. Participants were 30 female adults with no history of hearing loss or persistent tinnitus. Pre - and post-silence ALR and P300 recordings were obtained. After the first ALR recording they were exposed to 10 minutes of silence. They completed a Qualtrics questionnaire to report any tinnitus perception in silence. Absolute ALR and P300 waveform amplitudes and latencies were identified and were entered into an SPSS spreadsheet for data analysis. The mean age of the participants was 22.5 ? 3.9 years. When exposed to silence, eleven (36.7%) participants perceived tinnitus. Seven (63.6%) of the participants who perceived tinnitus were African American. There was no significant association between race and the perception of tinnitus. A statistically significant reduction in post-silence P300 amplitude was observed, (t29= 2.2, p=0.04). Thus, the neural response in the non-auditory regions involved in modulating auditory attention and the experience of auditory stimuli appears to be affected by silence. This may explain the negative effect of silence on tinnitus perception in individuals with tinnitus as well as the tendency for some individuals to experience tinnitus emergence when exposed to silence. Therefore, clinicians can continue to advice that patients with tinnitus avoid silence. ALR and P300 waveform latencies and amplitudes did not differ significantly between the participants who perceived tinnitus in silence and those who did not (p > 0.05). Whites had significantly larger N1 amplitudes than African Americans (F (1,25) = 4.4, p = 0.05, effect size 0.2).
