Transiently evoked otoacoustic emission amplitudes change with changes of directed attention
Physiol Behav.
1993 Apr.
Abstract
The effect of a visual and of an auditory task on the cochlea was studied by transiently evoked otoacoustic emissions (TEOAEs). TEOAE amplitude decreased during visual and auditory attention for all 13 subjects tested. The decreased TEOAE activity was noted predominantly within the 960 to 1920 Hz range during visual attention and within the 1920-2880 Hz range during auditory attention. Selective attention, by way of the olivocochlear medial efferent system, modifies cochlear micromechanical properties. Visual and auditory attention act on different areas of the cochlear partition.
