This study investigated the effect of selective attention on the distortion-product otoacoustic emission (DPOAE) level through the use of environmentally meaningful, contralateral auditory stimuli. Four different conditions were used for measurement: quiet, contralateral noise, contralateral speech (unattended), and contralateral speech (attended). A statistically significant suppression effect for both the noise and speech conditions was found. However, there was no support for an auditory selective attention effect on the distortion-product amplitude.

Abbreviations: ABR = auditory brainstem response, ANOVA = analysis of variance, DPOAEs = distortion-product otoacoustic emissions, IHC = inner hair cell, MES = medial efferent system, OAEs = otoacoustic emissions, OCB = olivochlear bundle, OHC = outer hair cell, SOAEs = spontaneous otoacoustic emissions, TEOAEs = transient evoked otoacoustic emissions
