AiSW 3201 Otoacoustic Emission Hearing Screening Instrument

Otoacoustic emission is a kind of audio energy produced in cochlea and released in external auditory canal through ossicular chain and tympanic membrane conduction. AiSW 3201 The otoacoustic emission hearing screening instrument uses transiently evoked otoacoustic emission and distortion product otoacoustic emission detection technologies. A certain intensity and frequency of stimulation sound is transmitted into the ear canal through the probe's loudspeaker. The audio signal of otoacoustic emission from the external auditory canal, recorded by the probe's microphone, is measured and analyzed. By testing the cochlear mechanism, we can determine whether the cochlea is functioning properly. In this way, the purpose of hearing screening is achieved. The otoacoustic emission hearing screening instrument conforms to the technical requirements of Type II otoacoustic emission hearing screening instrument in IEC 60645-6: 2022 Electroacoustics Audiometry Equipment Part 6: Otoacoustic Emission Measuring Instrument and JJF 1289-2020 Calibration Specification for Otoacoustic Emission Measuring Instrument of Audiometry Equipment. The product is composed of host, probe, charger, printer and printer charger.
