GB/T 7341.4-1998
ActiveAudiometers--Part 4:Equipment for extended high-frequency audiometry
听力计 第4部分 延伸高频测听的设备
Application Summary AI generated
This standard specifies technical requirements and test methods for audiometers used in extended high-frequency audiometry, covering frequencies above 8 kHz. It is applied in clinical audiology and occupational health settings to assess hearing sensitivity in the extended high-frequency range, which is critical for early detection of noise-induced hearing loss and ototoxicity monitoring. The standard ensures consistent calibration and performance of equipment used for specialized hearing tests beyond conventional audiometric frequencies.
