DIN 45642

Traffic Noise Immission Measurement

DIN 45642 specifies standardized methods for measuring noise immissions from road and rail traffic at receiver locations. This test quantifies sound pressure levels and frequency characteristics of traffic noise in the environment, typically at building facades or sensitive areas. Municipalities, environmental authorities, and transportation agencies require this test to assess compliance with noise limit values and evaluate environmental impact. Accreditation ensures measurements are reproducible, comparable, and defensible in regulatory and legal proceedings. Proper measurement following this standard is critical for noise action planning and protection of public health.

What it measures

  • Sound pressure level (Leq, LA) from traffic sources
  • Maximum sound pressure levels (Lmax, LAmax)
  • Frequency spectrum analysis
  • Temporal noise characteristics
  • Compliance with national noise limit values
