Behind-the-ear hearing aid with microphone mounted in opening of ear canal

摘要

Provided is a behind-the-ear hearing aid which enables a hearing aid wearer to easily estimate the position of a sound source in the front-back direction and can be more aesthetically satisfying when being worn. The behind-the-ear hearing aid is used while being fitted to an ear of the human body and comprises at least a micro-phone (101) for picking up ambient sound to generate an input signal, and a signal processing means (102) for generating an output signal on the basis of the input signal, and further comprises a behind-the-ear portion (110) capable of being worn behind the ear, and a receiver (103) for reproducing output sound on the basis of the output signal. When the behind-the-ear portion (110) is worn behind the ear, the microphone (101) is disposed in an opening of an ear canal (220) that is an extension of the ear canal and is closer to the eardrum than the plane defined by a helix (901), a tragus (902), and an earlobe (903) is.
