Correlation between Tinnitus and Spontaneous Otoacoustic Emissions

Abstract

We performed the band noise masker (BNM) therapy for the suppression of tinnitus. Spontaneous otoacoustic emissions (SOAEs) were measured before and after BNM therapy and the correlation between the efficiency of BNM therapy and changes of SOAEs was analysed.
There were no significant correlations between pitch of tinnitus and frequency of SOAEs, and loudness of tinnitus and amplitude of SOAEs. Before and after BNM therapy, the frequency and amplitude of SOAEs did not changed significantly.
In conclusion, it was predicted that SOAEs had little relation to tinnitus.
