Unlabelled:
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.
