Frequently asked questions
What is a sound level calibrator used for?
A sound level calibrator is used to verify the accuracy of sound level meters and noise dosimeters by generating a precise reference tone, typically 94 dB or 114 dB at 1 kHz.
How often should I calibrate my sound level meter?
Meters should be checked with an acoustic calibrator before and after each measurement session. Professional laboratory calibration is recommended every two years for certified accuracy.
Can I rely on the meter’s internal calibration check?
No. Internal checks do not test the microphone, which is the most sensitive component. An external acoustic calibrator is essential for reliable verification.
Why is regular calibration important for noise measurements?
Regular calibration ensures that environmental conditions, ageing, or mechanical stress have not affected measurement accuracy, helping maintain compliance with noise regulations.
Which instruments can be calibrated using SVANTEK acoustic calibrators?
SVANTEK acoustic calibrators are compatible with Class 1 and Class 2 sound level meters and noise dosimeters equipped with ½″ or ¼″ microphones, depending on the model.
Do SVANTEK acoustic calibrators require manual adjustment during calibration?
No. SVANTEK calibrators use automatic signal control to stabilise output levels, eliminating the need for manual correction and ensuring repeatable results.
How do I know when an acoustic calibrator is ready for use?
Once powered on, the calibrator automatically stabilises its output. Calibration can begin when the sound level or status indicator remains steady.
How often should an acoustic calibrator itself be verified?
Verification at an accredited laboratory is recommended every two years to maintain traceability and compliance with international calibration standards.
How long can an acoustic calibrator operate on batteries?
Battery life depends on the model and output level, but SVANTEK calibrators are designed for long operational life, supporting multiple calibration cycles on a single battery set.
