PERSONAL SOUND METER AND BROADCASTING/REPORTING SYSTEM

摘要

A sound monitoring system includes an identification card holder and a central processing and monitoring system in wireless communication with the identification card holder. The identification card holder is wearable on a body of a user, and includes a microphone for receiving sound and a visual sound indicator for displaying a noise level of the sound received through the microphone. The central processing and monitoring system processes sound data received from the identification card holder and transmits the processed sound data back to the identification card holder for display of the noise level represented by the processed sound data.
