Test / Retest Reliability of DPOAE and TEOAE / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Otoacoustic emissions (OAEs) are the objective and noninvasive methods to assess cochlear function. The purpose of the present study is to determine the short-term and long-term test/retest reliability of the distortion-product otoacoustic emissions (DPOAEs) and transient-evoked otoacoustic emissions (TEOAEs). MATHODS The short-and long-term reliability of DPOAE and TEOAE were examined in 11 normally hearing adults. DPOAE were collected in two basic forms consisting of audiograms and input/output (I/O) functions and reliabilities for TEOAE level, reproducibility index and peak stimulus level were calculated. RESULTS: The result of this study showed that the reliability of DPOAE and TEOAE was generally excellent. CONCLUSIONS: The DPOAE and TEOAE are highly reliable and useful tests to monitor the cochlear function for the purpose of study or clinical use in combination with other standard tests of audiometric function.
