    Product Description

    AiSW 1202 Pure tone audiometer can produce pure tone with different frequency and different sound level through electro-acoustic transducer, which is used to test hearing sensitivity of human ear with different frequency within hearing range and judge whether there is hearing disorder. It can be used to evaluate the degree of hearing loss and make a preliminary judgment on the type of deafness and the location of the lesion. 
    The pure tone audiometer shall meet the technical requirements of Type II pure tone audiometer in GB/T 7341.1-2010 Electroacoustic Audiometry Equipment-Part 1: Pure Tone Audiometer, JJG 388-2012 Verification Regulations for Pure Tone Audiometer and JJF 1592-2016 Type Evaluation Outline for Pure Tone Audiometer. 
    The product is composed of mainframe, power adapter, air guide headset (imported TDH-39P), bone guide headset (imported B71) and transponder.
