What we do

Three ways we use sound

Each sensor analyzes sound on the device. Only the analysis results and the audio from each event are sent out.

For cities

Smart city noise monitoring

Officials see where and when noise happens, block by block.

Sensors on existing poles log the type, level, location, and time of each noise event.
