<p>The hearing aid has a housing (11), and a signal processing device arranged in the housing and comprising an opto-electrical converter. An optical microphone (13) is arranged in an inner side of the housing and placed in the auricle (10) or in the auditory canal (14), where the microphone is fastened to an otoplastic. The microphone is connected with the signal processing device by using an optical waveguide (17) for optical signal transmission, where the waveguide is a fiber optical cable. A sound tube for transmission of sound to the auditory canal is attached to the housing. An independent claim is also included for a method for receiving sound for a behind-the-ear-hearing aid.</p> |
