Class 1 vs Class 2 Sound Level Meters

The most important distinction in professional noise measurement is between Class 1 and Class 2 meters according to IEC 61672 standards. Class 1 meters offer the highest accuracy with tighter tolerances across frequency and temperature ranges. These professional-grade instruments typically cost $2,500-$9,000 and are essential for environmental noise monitoring, regulatory compliance, and legal documentation where precision matters.

Class 2 meters provide slightly less accuracy but are perfectly adequate for occupational noise assessments, industrial hygiene, and most workplace applications. The meters in this roundup are generally Class 2 or unclassified consumer-grade meters suitable for relative measurements and general noise monitoring. For most users, Class 2 accuracy provides more than sufficient precision for practical applications.

The key difference is that Class 1 meters maintain accuracy across wider temperature ranges and frequency spectrums. For critical measurements like environmental impact assessments or legal disputes, Class 1 accuracy may be necessary. For workplace noise monitoring, home theater calibration, or noise complaint documentation, Class 2 meters like those reviewed here typically provide adequate accuracy.

IEC 61672 Standards Explained

IEC 61672 is the international standard for sound level meters that replaced earlier standards like IEC 60651 and IEC 651. Meters meeting this standard have been tested for accuracy, frequency weighting, and time weighting characteristics. The VLIKE VL6708 and Extech SL510 in this roundup specifically mention IEC651 Type 2 compliance, indicating they meet these international standards.

When purchasing a noise level meter for professional use, look for IEC 61672 compliance specifically mentioned in the specifications. This certification ensures the meter has been independently tested and meets minimum accuracy requirements. For casual use, this certification is less critical, but for compliance documentation or legal purposes, it provides essential credibility to your measurements.

A-Weighting vs C-Weighting

A-weighting and C-weighting are different frequency response curves that affect how the meter measures sound. A-weighting approximates the human ear's response to sound, de-emphasizing low and high frequencies. This makes it ideal for measuring environmental noise, occupational exposure, and most general applications where human perception matters.

C-weighting provides a flatter frequency response that includes more low-frequency content. This makes it better for measuring peak noise levels, machinery noise, and applications where capturing the full sound spectrum is important. For measuring noise that might damage hearing regardless of frequency, C-weighting provides more accurate peak measurements.

Most meters in this roundup offer both A and C weighting, which provides flexibility for different measurement scenarios. The RISEPRO HT-80A only offers A-weighting, which limits its applications but keeps the price down. For most users, having both options available is worth the small additional cost.
