The hearOAE (otoacoustic emission device) is a portable, handheld, battery-operated device that can detect hearing loss using Otoacoustic Emission technologies. The hearOAE device may be configured to support one or any combination of TEOAE (transient evoked otoacoustic emissions) or DPOAE (distortion product otoacoustic emissions).
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).
