Most are handheld, and a few can be mounted on the wall to monitor noise continuously. While there may be a few physical differences, they all do pretty much the same job. These meters go by many other names, too, such as sound pressure level meters, decibel meters, noise level meters, and noise dosimeters. A sock, or windshield, usually covers the end of the microphone to take out extraneous wind noise, though it can be removed if necessary. The information is converted to an electrical signal, interpreted by a microprocessor, and delivered to a display. If everything were completely still, there would be absolute silence.Ī sound level meter (SLM) uses a microphone containing a sensitive diaphragm to measure changes in the air pressure.
