Tips: How do I calibrate a digital noise level meter?

Calibrating a digital noise level meter requires the use of a sound level calibrator, usually set at a reference sound pressure level of 114 dB or 94 dB. Connect the calibrator to the microphone of the sound noise level meter, turn on the calibrator and check that the readings match the calibrator settings. If it does not match, you will need to adjust it according to the steps in the manual to ensure the accuracy of the digital db meter.
