To make it more interesting, we will scroll the display so that the last 8 measurements are graphed in real-time. Sound pressure level measurement (no weighting filter) FAST mode (125 ms) and SLOW mode (1 second), software configurable; Calibration Tests. In order to ensure the high quality of the Noise / Sound Level Sensor, each device is verified in an independent test laboratory. Tests are performed inside an isolated anechoic chamber. The sound sensor A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are considered to be noise. Loudness or sound levels are commonly measured in decibel(dB), we have some instruments which could measure the sound signals in dB but these meters are slightly expensive and sadly we do not have an out of box sensor module to measure sound levels in decibels.
