The Sound Level Sensor allows you to easily measure sound level in decibels (dB) in a variety of school settings. Simply connect and collect— no background knowledge of sound-level weighting, response times, or the decibel scale is needed to use this sensor.
The Sound Level Sensor is A-weighted, meaning it responds to sound loudness the same way the human ear does. It measures sound level to within 3 dB along a single range from 55 to 110 dB, with no need to switch between ranges during an experiment. You can monitor classroom sound levels, measure reverberation time, and investigate sound insulation.
