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 22):
A method of using audio-priming to count occupants, comprising:\n emitting, via an audio speaker accessible to a plurality of light fixtures arranged in an area, an ambient sound in a background environment of the area; adding, during a training mode, a specific number of occupants to the area; calculating a baseline audio-print for the ambient sound based upon each specific number of occupants added in the area during the training mode; comparing the baseline audio-print to the ambient sound to provide a baseline of change in ambient sound for each specific number of occupants added in the area; controlling, after the training mode, a microphone accessible to each of the plurality of light fixtures to sample audio in the area of the plurality of light fixtures; analyzing the sampled audio from the microphone to determine an audio frequency level of the sampled audio; determining whether the audio frequency level of the sampled audio is greater than a predetermined decibel level of the ambient background sound; recording audio in the area for a period of time when the audio frequency level is greater than the predetermined decibel level of the ambient sound in, the background environment of the area; calculating, via application of a fast Fourier transform (FFT) analysis, an audio-print for the recorded audio based upon a difference in a decibel level between the recorded audio and the ambient sound emitted into the area; comparing the calculated audio-print to the baseline audio-print to determine a corresponding number of occupants in the area when the calculated audio-print is approximately the same as the baseline audio-print; incrementing an occupant counter for each corresponding determined number of occupants when the calculated audio-print is approximately the same as the baseline audio-print.
