The hearing aid has a hearing aid housing and a microphone housing which are one-piece formed. The microphone is made of silicon. The hearing aid housing has a cover for the acoustic isolation of the microphone front volume from the sound inside the hearing aid and attached inside of the hearing aid housing. The microphone has a circuit board and is electrically connected to it by means of contact springs. The hearing aid has conductive tracks in MID technology applied to the circuit board.
