Abstract
An in-the-ear canal hearing aid comprises a microphone, an amplifier, an electromechanical transducer, for example in the form of a telephone, and an infrared detector. The hearing aid also includes an elongated extraction element for extracting the hearing aid from the ear canal. The extraction element is in the form of an optical conductor for conducting infrared radiation. One end of the optical conductor is mechanically attached to the hearing aid housing in a manner such that the end of the conductor is optically coupled to the infrared detector. As a result, the extraction element is a dual function device in which its second function is to conduct the infrared radiation to the infrared detector of the hearing aid.
