Introduction IN 1963 THE International Organization for Standardization (ISO) recommended a new set of zero reference levels for pure-tone audiometers. The concern and confusion which resulted has prompted a review of the concept of audiometer zero. This discussion will not be concerned with the validity of ISO values.

Pure-tone audiometry. Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125 kHz to 8 kHz with the use of headphones.
