Abstract
An acoustic pressure gradient sensor able to detect a sound signal. The sensor includes a mechanical-acoustic device formed of a sphere that has omnidirectional sensitivity to the pressure gradient, an electromechanical device that accommodates the mechanical-acoustic device and that transforms the stresses into electrical impulses, and an electronic device to process the electrical impulses. The electromechanical device is formed of two printed circuits that incorporate low noise amplifiers. The printed circuits are separated by beams. The arrangement of the beams marks out a triangular structure. Each of the beams carries a gauge to measure the stresses.
