Choice of four meters to meet your workplace noise monitoring needs
Noise meters, also known as decibel meters or sound meters, are electronic devices that can detect and quantify sound levels as measured in decibel units.
Sounds in the workplace can exceed the levels established by municipal or national law, including occupational safety and health standards. Measuring noise levels can help to reduce the risk of injury and maintain safety compliance.
Several factors affect noise level reading, including the distance of the meter from the sound source, the direction the sound faces, and whether the measurement is made outside or indoors, which affects sound dissipation and reverberation.
Noise meters are categorized by type or class, a measure of accuracy. According to the IEC 61672 standard, Class 1 meters are more accurate than Class 2, and must meet other performance and calibration requirements. Class 2 meters are suitable for general purpose use, including work noise and basic environmental sound level measurement. Use Class 1 meters in the laboratory or where greater sensitivity is required.
Other noise meter considerations include:
Microphone type, size, resolution, response time, and other capabilities
Data output: LCD screen and graphics displays; datalogging (downloads); chart recorders
Detection ranges: Low (30.0 to 80.0dB), Medium (50.0 to 100.0dB), High (80.0 to 130.0dB)
Certifications: Include traceability to NIST
Compliance with ANSI™ S1.4, ANSI S1.43, and IEC 616672 standards
Noise meters are typically portable, battery-powered, and may include a carrying case.
