Physiologically Derived DPOAE Measurement Methods
Description: PROJECT NARRATIVE Distortion-product otoacoustic emission (DPOAE) testing provides an objective and noninvasive measure for evaluating the health of a common site of age-related decline in the auditory system – the outer hair cells. We contend that the test performance of DPOAEs can be improved significantly by aligning the methods to evoke them with known, place-specific mechanical properties of the mammalian cochlea. In this project, stimulus frequencies and levels will be adjusted in a frequency-specific manner to maximize DPOAE generation and improve test performance for both screening for hearing loss and predicting hearing thresholds.
