HEARING APPARATUS AND METHOD FOR MEASURING DISTANCE BETWEEN HEARING APPARATUS AND EARDRUM

摘要

Hearing devices and methods are disclosed for measuring the distance between an eardrum and an hearing device. The hearing device includes a signal output unit configured to output a first measurement signal for measuring a distance between the eardrum and the hearing device; A signal identification unit for identifying a second measurement signal reflected from the eardrum and modulated from the voice signals collected by the microphone; And a distance determination unit comparing the first measurement signal and the second measurement signal to determine the distance between the eardrum and the hearing device.
