Sound Level Meter Instrument Information
Most commonly a handheld instrument containing a microphone. This microphone contains a diaphragm which responds to changes in air pressure caused by sound waves. The movement of the diaphragm is converted into a voltage signal and displayed on the readout of the mete.

Common Uses
- Measuring the sound level in critical applications, such as in a theater or in the noise put off of a running machine, such as a compressor.
- Completing noise pollution studies in the industrial, environmental and aviation industries.
