Most manufacturers and standards require the use of a sound level meter calibrator to check or calibrate a sound level meter before use. Calibration should be performed before and after each day of use and whenever the temperature or relative humidity changes significantly. Prior to and immediately after taking measurements, it is a good practice to check, using a calibrator, the ability of the sound level instrument to correctly measure sound levels.
