Acoustic measurements are made using a sound level meter. Acoustic refers to a sound that moves through the air. This contrasts with the term “audio,” which is also frequently used in the study of sound measurement. The sound that is transmitted electronically across cables and audio equipment is referred to as “audio.” sound level meter calibration is tough to do and numerous people don’t know how to fine-tune their sound level meters. Let’s now address the issues of sound level meter calibration and application.
Instructions for Calibration
- Find your barometer, acoustic calibrator, and sound level meter.
- Your sound meter should be turned on so that it can stabilize and adapt to the environment it will be used in. Go to the Calibration screen (but don’t begin the calibration process just yet).
- Put the calibrator over the mic capsule with care, being cautious not to distort the device or your sound meter, as this could harm the microphone.
- The calibrator should be turned on at the desired tone, which is typically 94 dB. You might want to verify your sound meter to this secondary tone on your calibrator, which is often either 104dB or 114dB, as a reference following the calibration process.
- Press “OK” once again inside your sound meter to start the calibration process. Keep the calibrator on until the process is finished, which typically takes 5 to 20 seconds depending on the version and the company.
- At this point, the sound meter will indicate whether it completed the calibration or not. You may now proceed to take your measurements if you passed the test.
- If the process fails, ensure that the calibrator is attached properly to the microphone and it is turned on at the right levels, and then repeat the calibration procedure by trying to remove the calibrator and begin from step 2.
Purpose of a sound level meter
To monitor and control noise from a range of sources, such as industrial facilities, rail and road traffic, and construction work, sound level meters are utilized. The numerous varied sources of sound and various features, when combined with typical urban scenarios like concerts, recreational parks, and residential and commercial neighbors’, present a variety of obstacles for the experts who evaluate them.
What is the function of a sound level meter?
A microphone, a preamplifier, frequency processing, and a display are all part of a sound level meter. The microphone helps to convert an audio signal into an electrical signal. Condenser microphones are the best choice for sound level meters because they combine high accuracy with stability and reliability.
