The Sound Level Sensor is designed to measure the intensity level of sound sources within proximity to the sensor. The sensor features three range switches to match the intensity range of the measured phenomena.
The sensor measures sound level in both the dBA and dBC scales. The dBC scale includes all frequencies incident on the Sound Level Sensor, whereas the dBA scale filters out some frequencies to more closely match the frequency response of the human ear.
The sensor also reports a measurement of sound intensity in μW/m2, which is calculated from the dBC measurement of the sound level.
