Application Summary AI generated

This standard specifies the reference equivalent threshold sound pressure levels (RETSPL) for pure tones delivered via supra-aural earphones, providing the baseline for calibrating audiometric equipment used in hearing testing. It is applied in clinical audiology, occupational health screenings, and hearing conservation programs to ensure accurate and consistent hearing threshold measurements across different devices and testing environments.
