摘要
A system and method for sensing acoustic sounds is provided having at least one directional sensor, each directional sensor including at least two compliant membranes for moving in reaction to an excitation acoustic signal and at least one compliant bridge. Each bridge is coupled to at least a respective first and second membrane of the at least two membranes for moving in response to movement of the membranes it is coupled to for causing movement of the first membrane to be related to movement of the second membrane when either of the first and second membranes moves in response to excitation by the excitation signal. The directional sensor is controllably rotated to locate a source of the excitation signal, including determining a turning angle based on a linear relationship between the directionality information and sound source position described in experimentally calibrated data.
