Device for use of mobile telephones by hearing aid wearers couples acoustic signal electrically into hearing aid and out of mobile telephone via connecting channel

摘要

The device couples the acoustic signal electrically into the hearing aid (7) and out of the mobile telephone (1) via a connecting channel (5). The non-acoustically transferred signal between the hearing aid and telephone has no acoustic or electromagnetic noise superimposed on it and the telephone is held at such a distance from the hearing aid that the inevitable noise field emitted by the telephone cannot affect the hearing aid.
