The invention is directed to a method of generating and measuring transiently evoked otoacoustic emissions (TEOAE) acoustic signals generated in the cochlea using a scheme of stimulating both inner ears simultaneously, left ear alone, and right ears alone with at least two different first and second averaging buffers per ear in a switching scheme with automated detection of contralateral suppression of TEOAE via statistical analysis of the differences of suppressed and unsuppressed responses.

Method and apparatus for automated detection of suppression of TEOAE by contralateral acoustic stimulation

An illuminated acoustical stimulation ear probe with outer ear illumination and a probe-fit status indicator.

Ear canal obstruction detecting acoustical stimulation ear probe

A method and device for automatically assessing loss of hearing sensitivity and compression (recruitment) with user defined frequency resolution by means of extrapolated DPOAE I/O functions and ABRs as well as for automatically fitting hearing aids without any cooperation of the subject tested using a device having a display screen attached to a handheld device generating and collecting otoacoustic emission signals and brain stem response signals into a programmed with a clinical audiogram with fitting parameters for hearing aids calculated on the basis of assessed hearing threshold and compression and identifying the type of hearing required for the individual.

Method and apparatus for automatic non-cooperative frequency specific assessment of hearing impairment and fitting of hearing aids
