Kind Code:
A3
Abstract:
Provided are methods and devices for evaluating dynamic middle ear muscle activity in a subject. A probe is provided having a speaker and a microphone in sound-wave communication with an eardrum associated with the middle ear muscle of the subject. A sound wave is generated from the speaker and transmitted to the eardrum. The sound wave that is reflected is detected and a reflected sound wave property measured.
