The purpose of the present study was to investigate the effect of attending to a speech stimulus on the amplitude of the distortion product otoacoustic emission (DPOAE). The distortion product otoacoustic emission is a measurement of the activity of the inner ear, specifically the outer hair cells in the ear. The activity of the outer hair cells depends upon the auditory nervous system; when it is stimulated, the outer hair cell activity is modified. Normal outer hair cells will create a large DPOAE amplitude. When a stimulus is presented to the opposite ear, the auditory nervous system acts upon the …
