Distortion-product otoacoustic emission test performance for ototoxicity monitoring.
INTRODUCTION A nonbehavioral method for monitoring ototoxicity in patients treated with cisplatin is needed because patients enduring chemotherapy may not be well or cooperative enough to undergo repeated hearing tests. Distortion-product otoacoustic emissions (DPOAEs) provide a nonbehavioral measure of auditory function that is sensitive to cisplatin exposure. However, interpreting DPOAE findi...
متن کاملDo "optimal" conditions improve distortion product otoacoustic emission test performance?
OBJECTIVES To determine whether an "optimal" distortion product otoacoustic emission (DPOAE) protocol that (1) used optimal stimulus levels and primary-frequency ratios for each f2, (2) simultaneously measured 2f2 - f1 and 2f1 - f2 distortion products, (3) controlled source contribution, (4) implemented improved calibration techniques, (5) accounted for the influence of middle ear reflectance, ...
متن کاملInfluence of calibration method on distortion-product otoacoustic emission measurements: I. test performance.
OBJECTIVE Calibration errors in distortion-product otoacoustic emission (DPOAE) measurements because of standing waves cause unpredictable changes in stimulus and DPOAE response level. The purpose of this study was to assess the extent to which these errors affect DPOAE test performance. Standard calibration procedures use sound pressure level (SPL) to determine specified levels. Forward pressu...
متن کاملAccuracy of distortion-product otoacoustic emissions-based ototoxicity monitoring using various primary frequency step-sizes.
OBJECTIVE A cisplatin ototoxicity monitoring protocol was recently proposed using distortion-product otoacoustic emissions (DPOAEs) measured in 1/48th octave steps over the highest obtainable quarter octave ( Dille et al, 2010 ). This protocol can take up to 40 minutes to complete in both ears among seriously ill patients in a potentially noisy test environment. The goal of the current study wa...

Phase characteristics and latency of 2f1-f2, 3f1-2f2, and 2f2-f1 acoustic distortion product otoacoustic emissions (DPOAEs) recorded in normally hearing adults have been described in a companion paper [Moulin and Kemp, "Multicomponent acoustic distortion product otoacoustic emission phase in humans. I. General characteristics," J. Acoust. Soc. Am. 100, 1617-1639 (1996)]. Phase-versus-frequency ...
