The use of beech pressure through phase-shifting channels in the gradient gradient, allows increasing its noise-tolerance: in the near field. The formula is an eqiectrostatic gradient sound pressure receiver containing a building with openings on the front and back steaks, inside which there is a fixed electrode with phase-shifting channels and located between the fixed electrode and the rear wall of the bottom. ma, characterized in that, in order to increase noise resistance, the fixed electrode is made with additional end-to-end phase-shifting channels located between the front wall and the diaphragm, sources of information taken feo attention during examination; 1.
