A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [1]

Measure sound loudness levels by using a microphone on your phone, laptop or desktop computer. Measure a true perceived loudness or use old SLP algorithm. Get exact ITU loudness measurements from audio files.

Jan 8, 2022 · An easy-to-understand explanation of how sound pressure level (SPL) meters can be used to measure noise.

Simply connect a microphone to your device and let our smart board noise monitor do the rest. Adjust the Max. noise slider to establish your desired sound threshold, and watch as the red-colored bar dynamically adjusts to reflect the current noise level in your classroom.
