This Technical Report describes air conduction hearing thresholds measured for pure tones at conventional audiometric frequencies and extended high frequencies using apparatus and procedure in accordance with relevant ISO and IEC standards. The subjects were otologically normal Japanese high-school students aged 15-17 years. Descriptive statistics of their threshold levels are presented in graphical and tabular forms. Analyses of the measured data showed that the median threshold levels did not significantly deviate from the reference level of 0 dB and that they differed depending on the earphones used: supra-aural or circumaural earphones. These measurement results might be used effectively for revision of ISO 7029:2000, which describes the method for calculating the estimated hearing sensitivity decline as a function of age.
