The aTymp system is a portable audiometric device intended for use in conduction of diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders with the help of acoustic impedance tests, including tympanometry, Eustachian tube function (for intact and perforated tympanic membrane), acoustic reflex and acoustic reflex decay.The target population for aTymp system includes all ages.During the Eustachian tube function tests patient should be able to understand and perform instructions to do maneuvers.
An assembly of battery-powered devices designed to record and analyse the faint sounds hair cells in the inner ear emit [otoacoustic emission (OAE)] in response to a stimulus (e.g., click, tone burst, pure-tone signals) to test for a deficiency of function in the ear during diagnostic evaluation and/or neonatal screening. It typically consists of a portable programmable unit, an OAE probe, and eartips. The stimulus signal is emitted via the probe inserted into the ear canal and the response is recorded via a microphone in the probe; OAEs are absent/reduced in patients with hearing loss. The system may be combined with other audiological devices (e.g., tympanometer, ABR device).
