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 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;
- wherein the processor is further configured to determine a ratio of direct sound energy and diffuse sound energy (DDR) for the incident sound as a function of the signals representative of the incident sound, and to determine a direction of arrival (DOA) for the incident sound based on the signals representative of the incident sound, and to determine the location of the source of the incident sound based on the determined DDR and the determined DOA.
