Abstract
A system includes a plurality of acoustic sensor elements co-located with one another, each acoustic sensor element of the plurality of acoustic sensor elements being configured to generate a signal representative of sound incident upon the plurality of acoustic sensor elements, and a processor configured to determine data indicative of a location of a source of the sound based on the signals representative of the incident sound. The plurality of acoustic sensor elements include a directional acoustic sensor element configured to generate a signal representative of a directional component of the sound.
Claims20
A system comprising:
- a plurality of microphones co-located with one another, each microphone of the plurality of microphones being configured to generate a signal representative of sound incident upon the plurality of microphones;
- and
- a processor configured to determine data indicative of a location of a source of the sound based on the signals representative of the incident sound;
- wherein:
- the plurality of microphones comprise a pressure microphone;
- the plurality of microphones comprise a directional microphone configured to generate a signal representative of a directional component of the sound, the directional microphone comprising a structure movably responsive to sound along a single axis over an entire audible frequency range;
- the processor is further configured to compare a signal generated by the pressure microphone with the signal generated by the directional microphone to determine a distance between the source of the sound and the plurality of microphones.
