ISO 1996-2:2017

Environmental Noise Sound Level Determination

This test method specifies procedures for measuring and assessing sound levels in environmental noise scenarios, including traffic, industrial, and community noise sources. It provides standardized measurement techniques, acoustic indices, and assessment criteria for evaluating noise exposure in outdoor and indoor environments. The test is essential for regulatory compliance, urban planning, and environmental impact assessments. Industries and authorities use this method to verify compliance with noise limits and to protect public health. ISO 17025 accreditation ensures reliable, comparable noise measurements across European jurisdictions.

What it measures

  • Equivalent continuous sound pressure level (LAeq)
  • Environmental noise indicators (Lday, Levening, Lnight)
  • Sound pressure levels at measurement locations
  • Noise descriptors and acoustic climate assessment
  • Temporal sound level variations
