Device for examination of ear of human being, has determination unit determining release threshold of stapedial reflex to vary intensity of additional sound wave until release of reflex determined from variation of acoustic otoemission

摘要

The device (1) has stimulation emitters (2, 3) and an ipsilateral sensor (4) placed in an external auditory canal of an ear, where the emitters emit stimulation sound waves to cause an acoustic otoemission of the ear. An additional emitter (5) is placed in the canal and emits an additional sound wave to release a stapedial reflex. A determination unit (14) determines release threshold of the reflex to vary intensity of the additional sound wave emitted by the additional emitter, until the release of the reflex determined from the variation of the acoustic otoemission measured by the sensor. An independent claim is also included for a method for examination of ear of living being i.e. human being.
