Abstract
The present disclosure describes systems and methods to evaluate auditory efferent function by exposing a patient to short-duration acoustic click stimuli to generate a click-evoked otoacoustic emission (CEOAE) occurring in each ear of the patient, and in response to exposing the patient to click stimuli, concurrently sampling outer hair cell activity (OHC) and medial olivocochlear reflex (MOCR; efferents) in each ear of the patient, monitoring the middle ear muscle reflex (MEMR) in each ear of the patient, and measuring a change in cochlear activity in the patient based on the CEOAE, MOCR, and MEMR of each ear of the patient.
Claims23
A method to evaluate auditory efferent function comprising:
- exposing a patient to short-duration acoustic activator click stimuli to generate a click-evoked otoacoustic emission (CEOAE) occurring in each ear of the patient;
- in response to exposing the patient to activator click stimuli, concurrently sampling an outer hair cell activity (OHC) via CEOAE and a medial olivocochlear reflex (MOCR) in each ear of the patient via the change in CEOAE;
- and
- monitoring a middle ear muscle reflex (MEMR) in each ear of the patient.
A system operable to monitor and evaluate auditory efferent function of a patient comprising:
- a processing device,
- wherein the processing device is configured to generate and expose a patient to a short-duration acoustic activator click stimuli to generate a click-evoked otoacoustic emission (CEOAE) in each ear of the patient,
- wherein the processing device is configured to concurrently sample an outer hair cell activity (OHC) and an efferent activity in each ear of the patient in response to exposing the patient to the activator click stimuli,
- wherein the processing device is configured to monitor a middle ear muscle reflex (MEMR) in each ear of the patient, and
- wherein the processing device is configured to measure a change on cochlear activity in the patient based on the CEOAE, the efferent activity, and the MEMR of each ear;
- a first probe and a second probe,
- wherein the first and the second probes are configured to transmit the activator click stimuli to each ear of the patient, and
- wherein the first and the second probes are configured to record the CEOAE, the efferent activity, and monitor the MEMR of each ear of the patient;
- a user interface;
- and
- a monitor.
One or more non-transitory computer-readable media having instructions stored thereon, when executed, cause at least one processing device to:
- generate a short-duration acoustic activator click stimuli to generate a click-evoked otoacoustic emission (CEOAE) occurring in each ear of a patient;
- sample an outer hair cell activity (OHC) and a medial olivocochlear reflex (MOCR) in each ear of the patient;
- monitor a middle ear muscle reflex (MEMR) in each ear of the patient;
- and
- measure a change in cochlear activity in the patient based on the CEOAE, OHC, and MOCR of each ear of the patient.
