  • Method and apparatus for automated detection of suppression of TEOAE by contralateral acoustic stimulation
    Patent number: 10743798
    Abstract: 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 measuring the Acoustic Reflex with artifact management by using multiple probe tones
    Publication number: 20190038188
    Abstract: A method and apparatus is disclosed that performs a measurement of the acoustic reflex. In contrast to prior art, more than one probe tone is used simultaneously to detect the acoustic reflex and separate the reflex response from artifacts. In a preferred configuration, at least one probe tone frequency is selected to be higher than the middle ear resonance frequency.
