Occupational Noise Exposure Measurement
This standard specifies methods for measuring and assessing noise exposure of workers in occupational environments to determine compliance with exposure limits and identify hearing protection needs. The measurement protocols account for temporal variations in noise and worker movement to characterize daily noise exposure levels. Results are critical for occupational health and safety compliance, hearing loss prevention programs, and workplace risk assessment. Accredited laboratories ensure measurement uncertainty, calibration standards, and data interpretation meet regulatory requirements for legal and health-safety defensibility.
What it measures
- Equivalent continuous A-weighted sound pressure level (Leq,8h)
- Peak sound pressure levels and impulsive noise
- Daily noise exposure level (LEX,8h)
- Frequency-weighted noise exposure
