Abstract

Distortion Product Otoacoustic Emission (DPOAE) was used to assess outer hair cells. The aim of this study is to assess the damage to outer hair cells of the noise model Rattus norvegicus by assessing the Signal to noise ratio (SNR). Twenty-seven Rattus norvegicus were grouped into 3: controls; 2-hours 100 dB noiseexposure; and 2-hours 110 dB noise-exposure. DPOAE was assessed 3 times in the beginning before treatment, 2 hours after the second day of exposure (day 2), and after 3 days of no exposure (day 5). The results showed that the SNR of DPOAE after the noise exposure decreases at all frequencies compared to before the treatment. A significant decrease in SNR especially at 2000Hz - 4000Hz frequencies. These results suggest that DPOAE may be used as a sensitive procedure at various frequencies for early diagnosis and screening of NIHL.
