AiSW 1202 Pure-tone Audiometer

Dual channel clinical diagnostic audiometer

The AiSW 1202 pure-tone audiometer consists of a host, two air conduction earphones, a bone conduction earphones, a patient response trigger, and a power adapter. The built-in microprocessor of the host controls the sound card to emit pure tones of different frequencies and sound levels through an electroacoustic transducer, which is used to test the hearing sensitivity of the human ear at different frequencies within the auditory range and determine whether there is hearing impairment. Can be used to evaluate the degree of auditory loss, make judgments on the type of hearing loss and the location of lesions. During the test, the subjects themselves determine whether they have heard the sound emitted by the earphones. The minimum sound intensity that can be heard at each frequency is taken as the hearing threshold, and the hearing threshold at each frequency is connected to the hearing coordinate graph, which is the hearing graph. The measurement results are directly displayed on the host screen, stored inside the host, and can be printed by the built-in printer. If necessary, they can be connected to a computer for post-processing. Suitable for testing and analyzing human ear hearing threshold in clinical units. The AiSW 1202 pure tone audiometer complies with the Type 2 requirements of IEC 60645-1:2017 Electroacoustics—Audiometric equipment— Part 1: Equipment for pure-tone and speech audiometry.

Main features:

Dual channel clinical diagnostic audiometer (Type 2);

Provide pure tone testing and speech testing;

Display, store, and retrieve test results directly from the host without the need for a computer, and print them with a built-in printer;

The computer controls the host to work and print through the USB interface.
