Analisys of high frequency auditory thresholds in individuals aged between 18 and 29 years with no otological complaints

Braz J Otorhinolaryngol. 2007 Mar-Apr;73(2):215-25. doi: 10.1016/s1808-8694(15)31069-7.

Abstract

Recent studies analyzing audibility thresholds at frequencies over 8 KHz have brought new perspectives on the investigation of auditory damage. These studies, however, have not yet reached a consensus on normal standards for auditory thresholds at these frequencies.

Aim: To analyze the results of high frequency auditory thresholds in individuals aged between 18 and 29 years with no otological complaints.

Type of study: A prospective, cross-sectional study.

Methods: 60 conventional audiometries were done and 51 of these exams were within normal limits in individuals aged 18 to 29 years. These selected individuals underwent high-frequency audiometry using the AMPLAID 460 device and Sennheiser HD 520 II earphones, and thresholds were obtained in dB HL Results: There was no significant difference in auditory thresholds between males and females. High-frequency auditory thresholds were obtained for individuals with no otological complaint, aged between 18 and 29 years.

Conclusion: It has been suggested that such data could be used as a normal reference for further studies with similar standard equipment, to analyze auditory alterations presented in young individuals.
