Application Summary AI generated

This standard specifies the reference equivalent threshold sound pressure levels (RETSPLs) for pure tones from 8 kHz to 16 kHz, used to calibrate audiometric equipment for high-frequency hearing testing. It is applied in audiology clinics, occupational health screening, and hearing research to ensure accurate and consistent measurement of hearing thresholds at extended high frequencies. The standard is critical for evaluating noise-induced hearing loss and monitoring auditory function in industries with high-frequency noise exposure.
