Abstract:
System and method examples offer ways to count occupants in an area by sound. A system includes a data network, a light fixture having intelligent driver circuitry coupled to a light source, a lighting control device to control a light output and operations of the light source in an area, and a microphone coupled to the lighting control device. The lighting control device includes programming that configures a processor to control the microphone to sample and detect sound in the area, determine a location of the detected sound relative to a position of the microphone coupled to the lighting control device, and increment an occupant counter to correspond to each newly determined location of sound in the area for a predetermined period of time.

Claim (Index 12):
A method of using sound localization to count occupants, comprising:\n controlling a microphone accessible to each of a plurality of light fixtures to sample sound in an area; analyzing the sampled sound from the microphone accessible to each of the plurality of light fixtures to detect an audio frequency and decibel level of the sampled sound; calculating, when the audio frequency and decibel levels are at least a predetermined threshold level, location information of the sampled sound, wherein the calculating comprises:\n determining a time, intensity, and frequency of the sampled sound in the area; \n comparing a phase of the sampled sound using the determined time, intensity and frequency of each sampled sound to determine an order of sound reception of the sound to the microphone in the area, and based on the comparison, provide a noise vector of the sound, wherein the order of sound reception represents a location and voice frequency of an occupant in the area;\n incrementing an occupancy counter based on each noise vector; and \n storing the order of sound reception information and an identification of the microphone from which the sound is received in a memory.
