Electrical parameter detecting method for e.g. human, involves eliminating signal from isolated response, and obtaining cochlear type microphonic potential representing intralabyrinthine pressure of subject

摘要

The method involves sending type sound stimulations emitted by a stimulation module (16) towards cochlea at alternate phases, and collecting electrical responses of the cochlea and auditory nerve to the stimulations. A component is isolated from a response corresponding to average electrical responses to a positive phase stimulation. Signals are eliminated from the insulated response, where temporal source of the signals is identical to a temporal source of the stimulation. Cochlear type microphonic potential representing intralabyrinthine pressure of subject is obtained. An independent claim is also included for an apparatus for detecting electrical parameter based on intralabyrinthine pressure of subject, comprising sound stimulation transmitting module.
