Application Summary AI generated

This standard provides the statistical distribution of hearing thresholds for otologically normal individuals aged 18 to 25 years under free-field listening conditions. It is applied in audiology research, hearing aid calibration, and environmental noise assessment to establish baseline hearing sensitivity data for young adults. The standard ensures consistent reference values for evaluating hearing loss or noise impact in clinical and occupational settings.
