Abstract

This report explains the development of a sound measuring system for continuous monitoring of sound levels. Dedicated telephone lines are used for data transmission so that sound level data can be monitored at installations far from the area of concern. This allows the sound sensing equipment to be left unattended and thereby greatly reduces the manpower costs of operation. That predetermined data conditions can be detected when they occur and corrective action can be taken immediately at the data receiving installation further justifies the method used. Background information and general need for such a system are discussed. Growing public concern with noise is creating a demand for more and better sound measurement devices and for more control of unnecessary noises. For description, the system is divided into functional sections. The sections are described and design considerations are given in order of data flow starting with the sound sensing devise, or microphone, and ending with the warning system which alerts the operator when a predetermined signal level has been exceeded. Circuits to detect selected conditional of excess sound and to control the alarm to these conditions are included.
