FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, particularly microphones. Microphone with Hall effect comprises housing, in which sensitive element is fixed, containing membrane from semiconductor arranged above permanent magnet, and connected by DC circuit on one side U0 and measuring circuit Umeas.X., from above on membrane is rigidly installed film with strain gauge and measuring circuit Umeas.R, an audio signal reaches a sensitive element through a horn mounted in the housing above a membrane; the measured signal reaches an amplification unit, an analogue-to-digital converter and a computer for further processing.
EFFECT: wider range of recorded audio frequencies and high quality of receiving sound waves.
