Schalldrucksensor

The Sound Level Sensor is a simple, easily-operated sensor to measure and investigate sound levels in classroom environments. It 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.

For in-depth sound studies, the Sound Level Meter (SLM-BTA) is a better tool for high school or college physics. If you are interested in collecting sound waves data, use the Vernier Microphone (MCA-BTA).
