Abstract: A system for noninvasive in vivo functional imaging of the human ear and measurement of nanometer scale motion of the tympanic membrane under various acoustic excitations, and identification of vibration patterns that vary between human subjects in response to sound. By combining spectrally encoded imaging with phase-sensitive spectral-domain interferometry, high-resolution imaging of the membrane surface is obtained within a fraction of a second, through a handheld imaging probe. The detailed physiological data obtained allows measuring a wide range of clinically relevant parameters for patient diagnosis, and provides a new tool for studying middle and inner ear physiology. Use of a line measurement technique, without mechanically scanning the probe beam, enables characteristics of the membrane vibration to be measured, in a time scale of tenths of a second, thereby reducing the possibility of inaccuracy because of movements of the hand-held instrument.

Abstract: Estimating inner and middle ear pathologies and conditions, such as issues caused by effusion in the ear, from wideband acoustic immittance can be accomplished by use of an analog-electric model of an ear canal and inner ear. The model is utilized to convert acoustic measurements into output data. The output data can be used to train a machine learning network to identify classifiers that would indicate the presence of an issue in the ear, such as the presence and amount of effusion in the ear. The model is based upon ear mechanics and includes a number of inputs from the acoustic measurements that are fit and converted to the output data that can be compared to measured data for hearing loss to train a system to quickly and easily diagnose an estimated effusion volume or other condition, such as via a diagnostic tool.

Abstract: The adjustment of a hearing device is to be improved and configured in a more user-friendly fashion. To this end, a method is proposed whereby the hearing device is set individually to the user and is inserted at least partially into the auditory canal of the user. Finally an in-situ measurement of the acoustic impedance of the auditory system of the user including at least part of the auditory canal of the user is implemented with a tympanometric method. An automatic correction of the individual setting of the hearing device can take place on the basis of the results of the in-situ measurement.
