Digital Sound Level Meter
Digital Sound Level Meter
Type : ACS56
Sound level meter is used for acoustic (sound that travels through air) measurements. It is commonly a hand-held instrument with a microphone. ACS56 combines precision with stability and reliability. The diaphragm of the microphone responds to changes in air pressure caused by sound waves. Sound level meters are commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental, mining and aircraft noise.
