title: Analisys of high frequency auditory thresholds in individuals aged between 18 and 29 years with no otological complaints.
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.
  
  
  OBJECTIVE
  To analyze the results of high frequency auditory thresholds in individuals aged between 18 and 29 years with no otological complaints.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
