The Sound Level Meter is used to measure sound level in decibels (dB). Switches on the meter are used to select dBA or dBC weightings and fast or slow response times. The Sound Level Meter has an LCD panel to use it as a stand-alone device. A Maximum Level Hold switch provide flexibility in the standalone mode.
If you are interested in collecting sound waves, use the Vernier Microphone.
