• Calibration of most brands of sound meter, both type 1 and type 2 sound meters.
• Regular calibration ensures accurate test results and allows comparison to a known standard.
• Can perform calibrations on sound level meters and calibrators of both Class I and Class II variations.
• Three kinds of sound level meters: conventional, integrating-averaging, and integrating sound level meter.
• Frequency weighting A is mandatory for all sound meters to protect workers against noise-induced deafness.
• Frequency weighting C is only mandatory for sound level meters conforming to class 1 tolerance limits.
Sound Level Meters
• Sound level meters measure sounds within the human hearing range.
• Components include a microphone, signal processor, and display device.
• They can be self-contained or comprise separate components in enclosures.
• They are classified into three groups: Group X, Group Y, and Group Z.
• Classification varies based on accuracy, with Class 1 having a wider frequency range and tighter tolerance than Class 2.
• Calibration involves measuring and recording environmental conditions, visual inspection, and checking voltage delivery.
• A sound calibrator is used to calibrate sound level meters, usually conforming to class 1 or class 2 specifications of IEC 60942.
• Calibration frequency check is usually performed, and the sound level meter can be adjusted to indicate the required sound pressure level.
• Other periodic tests can be performed depending on the type and construction of the sound level meter.
