AiSW 2101 Type I Tympanometer Wide Clinical Testing Range

AiSW 2101 The middle ear analyzer transmits certain intensity detection sound to the ear through the loud speaker of the probe, and measures the sound pressure level in the ear canal through the microphone of the probe. Because ear canal pressure or middle ear muscle activity will change the acoustic characteristics of the middle ear system, different sound pressure levels can be measured at the probe under different ear canal pressure or middle ear muscle activity. By monitoring the change of sound pressure level in the measuring system, acoustic compliance properties of the tympanic membrane and the auditory ossicle chain for acoustic energy conduction as measured from changes in the equivalent volume of sound . The middle ear analyzer shall comply with the technical requirements of Type I ear acoustic impedance/admittance measuring instrument in GB/T 7341.5-2018 Electroacoustical audiometry equipment-Part 5: Measuring instrument for ear acoustic impedance/admittance, JJG 991-2017 Verification code for ear acoustic impedance/admittance measuring instrument and JJF 1771-2019 Type evaluation outline for impedance audiometer (ear acoustic impedance/admittance measuring instrument). The product is composed of host, power adapter, cable probe, air guide headset and upper computer software.
