Ensuring Precision & Accuracy of Your Sound Level Meters

Sound pressure level meters play an important role in determining if industrial noise levels fall within OSHA standards, or if community noise pollution exceeds municipal noise ordinances. Regular calibration plays an important part of maintaining accuracy and performance of your equipment. Wear and tear of sound pressure level meters will happen over time, causing sound level instruments to measure noise imprecisely. Regular sound level meter calibration will ensure that your instruments remain a valuable investment, and proper calibration is an important factor in their performance.
