FIELD: physics, acoustics. ^ SUBSTANCE: hearing aid comprises electronic device for processing of sound installed behind ear of person who uses hearing aid, at that device for sound processing contains microphone, electronic device for sound amplification and electronic component for processing of sound connected to microphone. Sound processing in electronic device for sound amplification and electronic component for sound amplification is programmed. Receiving device is installed inside acoustic meatus according to principle of opened ear, at that receiving device comprises loud speaker and intermediate connection part installed between receiving device and electronic device for sound processing placed behind ear. Intermediate connection part comprises electroconductive element that provides electric connection between electronic device for sound processing and loud speaker. Device contains retaining wire that branches from at least one of following elements: from intermediate connection part or from receiving device, at that mentioned retaining wire configuration is arranged so that receiving device is located in part of acoustic meatus so that receiving device does not contact with any part of external acoustic meatus of ear whenever this device is inserted into external acoustic meatus of ear. ^ EFFECT: higher efficiency and convenience of hearing aid. ^ 70 cl, 7 dwg |
