Noise Monitoring WebCam

The WebCam view at right is of traffic entering and leaving Swarthmore College on Whittier Place. A calibrated microphone, mounted on the camera, senses noise from construction and other traffic. Through a wireless video/audio link, the signals are transmitted to a computer which analyzes the microphone output and calculates A-weighted decibels (dBA).

A graph (to appear below) of the noise level versus time, as well as summary statistics, will keep nearby residents informed about noise levels. Associated with each noise event over 85 dBA is a snapshot from the camera.
