Transient evoked otoacoustic emissions (TEOAE) of 153 patients of various ages with normal or nearly normal hearing in the low, high or middle frequency ranges (different aetiologies) have been recorded. We found that the rate of detection of otoacoustic emissions depends on the width of the frequency range of preserved hearing. Single cases of narrow bands of hearing in the middle frequency region showed this region's significance for the high detectability of TEOAE. Although the investigated population consists mainly of adults, conclusions for the use of the TEOAE method for infant screening are drawn.
