Abstract:
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.

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
