Source: IEC 61672-1:2013 standard specifications. Actual product performance may vary by manufacturer.

Key Technical Features Buyers Evaluate:

1. Frequency Weighting (A/C/Z): A-weighting (dBA) mimics human ear response and is required for occupational safety measurements. C-weighting (dBC) captures low-frequency noise and is used for entertainment venue compliance. Z-weighting (flat) provides unweighted measurements for technical analysis. Professional buyers expect at least A and C weighting options.

2. Time Weighting (Fast/Slow/Impulse): Fast (125ms) and Slow (1s) response times are standard. Impulse weighting is required for measuring short-duration noise events like gunshots or hammer strikes. Industrial safety applications typically require Fast and Slow options.

3. Data Logging and Connectivity: Modern buyers increasingly expect USB or Bluetooth connectivity for data transfer, along with onboard memory for extended monitoring sessions. Smart meters with AI-powered analytics and cloud integration represent the fastest-growing segment, though they command premium pricing.

4. Calibration Requirements: Professional buyers often require calibration certificates traceable to national standards. Some jurisdictions mandate annual recalibration for compliance measurements. Suppliers should clarify whether products ship with factory calibration certificates and whether recalibration services are available.

BSWA stuff is actually a pretty reasonable pick if you're on a budget. They meet IEC class specs and are way cheaper than the big names. For most industrial safety work, Class 2 is totally adequate ^[4].
