FIELD: for medico-biological purposes. SUBSTANCE: microphone has a cylindrical casing in the form of sleeve; positioned in the casing are an electrostatic screen, dielectric disk whose internal surface has flat electrodes connected to the RF current generator processing unit. The specific feature of the microphone is the use of the conducting layers of the patient's skin as a movable electrode. The processing unit is made as a symmetrical voltage follower and diode detector. The current generator outputs are connected to the electrodes that are connected to the processing unit input. EFFECT: facilitated procedure. 2 cl, 2 dwg
