Abstract:
1. A sensor system comprising at least one directional sensor, each directional sensor comprising: at least two compliant membranes for moving in reaction to an excitation acoustic signal; and at least one compliant bridge, each bridge 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, wherein each directional sensor is provided with a sensor for sensing vibrations of the at least two membranes and circuitry for comparing the sensed vibrations of the at least two membranes for determining directionality information about the location of a sound source of the excitation signal, and thereafter calculate an azimuth angle that describes the location of the sound source relative to a reference.
