Distortion product otoacoustic emissions (DPOAEs) have been accurately measured with an intensimetric technique, involving simultaneous measure of pressure and velocity in the ear canal, which allows one to correctly calibrate both the input stimuli and the otoacoustic emission (OAE) level. Suitable combinations of standard intensimetric quantities, active intensity and power density [Stanzial, Shiffrer, and Sacchi, J. Acoust. Soc.

Abstract

Distortion product otoacoustic emissions (DPOAEs) have been accurately measured with an intensimetric technique, involving simultaneous measure of pressure and velocity in the ear canal, which allows one to correctly calibrate both the input stimuli and the otoacoustic emission (OAE) level. Suitable combinations of standard intensimetric quantities, active intensity and power density [Stanzial, Shiffrer, and Sacchi, J. Acoust. Soc. Am. 131, 269-280 (2012)], are used to equalize the stimuli transmitted to the middle ear, and to estimate the DPOAE level emitted by the eardrum. The DPOAE intensimetric spectra are consistent with those recorded with a high-quality conventional otoacoustic probe with state-of-the-art calibration of both stimulus and OAE response [Charaziak and Shera, J. Acoust. Soc. Am. 141, 515-525 (2017)], demonstrating the applicability of the intensimetric method to OAE measurements.
