Title

STUDY OF NOISE EFFECTS ON RABBIT'S HEARING STATUS USING DISTORTION PRODUCT OTOACOUSTIC EMISSIONS

Pages

  114-124

Abstract

 Background and Aim: Noise-induced HEARING LOSS is the most common problem in industrial areas.This study aimed to determine effects of excessive noise exposure on measurable characteristics of DISTORTION PRODUCT OTOACOUSTIC EMISSIONS (DPOAEs) in rabbits.Methods: The study was carried out on 12 adult male New Zealand White rabbits including case group - exposed to 500-8000 Hz broadband WHITE NOISE with 100 dBA SPL for 8 hours per day in 5 consecutive days - and control group. After three days period of acclimatization to the experimental condition, rabbits' hearing status in each group were measured by DISTORTION PRODUCT OTOACOUSTIC EMISSIONS on days zero means before the study was initiated as a baseline, eight, one hour after the latest exposure to noise, and ten. The recorded results were analyzed using SPSS software.Results: Highest mean DISTORTION PRODUCT OTOACOUSTIC EMISSIONS amplitudes in case group were allocated to frequencies of 5888.50 Hz, 8166.50 Hz, 9855.00 Hz, 3956.00 Hz, and 3098.50 Hz, respectively. However, the lowest mean DISTORTION PRODUCT OTOACOUSTIC EMISSIONS amplitude was related to frequency of 588.00 Hz (p=0.001).Conclusion: This study revealed that DISTORTION PRODUCT OTOACOUSTIC EMISSIONS amplitude shifts due to noise occur first in high and then in middle frequencies. Additionally, exposure to noise can decrease DISTORTION PRODUCT OTOACOUSTIC EMISSIONS amplitudes. We conclude that DISTORTION PRODUCT OTOACOUSTIC EMISSIONS can be a reliable test for estimating personal susceptibility to noise-induced HEARING LOSS.
