It is now generally accepted that otoacoustic emission (OAE) was an objective and non-invasive test for the functional exploration of active micro-mechanical characteristics of outer hair cells. And OAE has been widely used as a tool for hearing screening test. So the purpose of this study was to evaluate of the usefulness of two-channel OAE system as a hearing screening test. Transientevokedotoacoustic emission (TEOAE) and distortion product otoacoustic emission (DPOAE) were measured in each ear of eighteen adults (11 males;7 females) with normal hearing with ILO v6 two-channel OAE system. Results as followed. TEOAE and DPOAE amplitudes with unilateral stimulation were larger than with bilateral stimulation except for DPOAE amplitudes of the right ear. But there were not the significant difference for unilateral and bilateral stimulations as a whole. Therefore this study showed that two-channel OAE system will be usefully applied as a hearing screening test.
Key Words: Otoacoustic emission·Unilateral and bilateral stimulations·Two-channel OAE system.
중심단어: 이음향방사· 일측성 및 양측성 자극· 두 채널 이음향방사 시스템.
