Abstract
- Distortion product otoacoustic emissions(DPOAEs) have emerged as a promising clinical tool for measuring hearing status. This investigation examined the influence of four variable (test/retest reliability, test environment, gender and number of measurement points of resolution/octave) on the DPOAE response when obtained using a commercially available system, Otodynamics ILO92. Twenty normal hearing adults(10 males and 10 females) served as participants in this study. DPOAE measurements were obtained over three test sessions(baseline, 1 week retest, and a 10 minute retest following the one week measurement). Results showed that: 1) correlations were high across the three test sessions;2) test environment considerably affected the DPOAE measures below 4kHz;3) DPOAE amplitudes were significantly greater in females than males at 3 and 6kHz;and 4) DPOAE amplitudes were not affected significantly by the number of resolution points employed.
