Abstract
A method of generating and measuring transiently evoked otoacoustic emissions (TEOAE) acoustic signals generated in the cochlea using a scheme of stimulating both ears simultaneously and one of each ears in a switching scheme with automated detection of contralateral suppression of TEOAE via statistical analysis of suppressed and unsuppressed responses.
Claims23
A method to automatically detect Transient-evoked Otoacoustic emissions (TEOAE) contralateral suppression, by:
- a. exposing a patient to sound stimuli testing to generate TEOAE given off by the inner ear,
- b. recording the TEOAE in both ears simultaneously with and without suppressors in a cycling/alternating scheme with at least two separate averaging buffers per ear to form averaged recordings of unsuppressed and suppressed states, where the TEOAE stimulus is also used as the suppressor for the contralateral ear, and
- c. applying signal statistics to the averaged suppressed and unsuppressed recordings to statistically detect contralateral suppression.
- A method according to claim 1, including applying a stimulus sequence that records suppressed and unsuppressed TEOAE in both ears by switching between stimulating both ears, then a first ear and then a second ear.
1 more element
An apparatus to automatically detect Transient-evoked Otoacoustic emissions (TEOAE) contralateral suppression comprising:
- a. a sound generator to expose a patient to sound stimuli to evoke TEOAE given off by the inner ear and/or to suppress TEOAE in both ears in a cycling/alternating scheme, containing periods where both ears are stimulated, or only one of each ears is stimulated
- b. a recorder to record TEOAE with and without suppressor in a cycling/alternating scheme in at least two separate averaging buffers per ear to form averaged recordings, and
- c. a computer to apply signal statistics to the averaged recordings of suppressed an unsuppressed recordings to statistically detect contralateral suppression.
