Hearing device associated with a method of estimating ear shape

摘要

The present invention provides a hearing instrument capable of estimating the shape of the ear of a user of a hearing instrument wearing the hearing instrument, and a method of estimating the shape, in order to reduce the problem of the hearing instrument that does not fit acoustically. A hearing instrument (2) has an ear canal microphone (10), an external microphone (8) and a receiver (16). An external microphone acquires an external input signal, and a receiver transmits an output signal. An ear canal microphone is used to obtain an ear canal microphone input signal, and an ear shape is estimated based on the external input signal and the ear canal microphone input signal.
