[Age-related aspects of pure tone threshold in extended band by air].

In addition to registration of pure tone threshold audiometry in the standard frequency band and acoustic impedance audiometry, tone hearing thresholds were registered conventionally in extended frequency band (9-20 kHz) by air. A total of 103 otologically healthy volunteers (206 ears) aged 14 to 67 years participated in the trial. The results can serve as the standard in examination patients with pure-tone threshold audiometry by air in extended frequency band.
