Abstract

See full text

A sound-detection and alerting system (SDAS) is designed for use in hospitals, offices, or other environments where excessive noise levels are of concern. The SDAS depends on several variables to trigger an alarm so that false alarms are kept to a minimum. A microphone circuit captures acoustic energy which is limited to specific frequencies by a bandpass filter. A comparator integrates the various frequencies and compares them to a threshold signal. A delay timer ensures that signals exceeding the threshold signal are persistent for a pre-determined period of time.
