Sound Level Meter FAQ
Q: What is the difference between class 1 and class 2 sound level meters?
A: Class 1 sound level meters are precision instruments with tighter tolerances (±0.7dB) and extended frequency ranges (typically 20Hz-20kHz), used for laboratory-grade measurements. Class 2 devices like ours (±1.4dB, 31.5Hz-8kHz) are general-purpose meters suitable for most field applications while maintaining excellent accuracy for occupational and environmental noise measurements.
Q: How often should I calibrate my sound level meter?
A: For professional use, we recommend annual calibration by an accredited laboratory. Additionally, you should perform an acoustic calibration check before each use or series of measurements using a portable calibrator. Environmental conditions (temperature extremes, humidity) or rough handling may require more frequent calibration checks.
Q: Can I use this sound level meter for OSHA compliance measurements?
A: Yes, our sound level meter meets OSHA 1910.95 requirements for noise measurement when used with proper procedures. It includes both A-weighted (for overall noise assessment) and C-weighted (for impact noise) measurements, along with slow response settings needed for OSHA-compliant measurements. Always ensure you're using the latest version of relevant standards.
