Sound Level Meters

Sound level meters are precision instruments used to measure acoustic pressure levels in decibels (dB) across standard frequency weightings (A, C, Z). They are fundamental tools for occupational health professionals, acoustical engineers, and environmental scientists who assess noise exposure, design noise control solutions, and verify compliance with workplace and environmental noise regulations.

Instruments range from basic handheld meters for spot noise level checks to Class 1 precision analyzers with data logging, real-time frequency analysis, and octave band filtering. Personal noise dosimeters are worn by workers throughout a shift to measure cumulative noise exposure for compliance with OSHA, NIOSH, and EU Noise at Work Directive requirements. Measurement microphones and accessories including windscreens, acoustic calibrators, and tripods are also part of this category.

Typical Applications

Occupational noise exposure assessment in factories, construction sites, and airports
Environmental noise surveys for urban planning, permitting, and residential impact studies
Noise compliance testing for machinery and consumer products under CE and other certifications
Architectural acoustics and building sound insulation performance verification
Hearing conservation program support through personal noise dosimetry
HVAC noise and vibration troubleshooting in commercial and industrial buildings
