Railway Wheel Squeal and Curve Noise Assessment
This test method characterizes squeal and curve noise generated by railway wheels during operation, particularly in tight curves and low-adhesion conditions. The evaluation focuses on wheel-rail interaction noise to identify problematic frequency bands and noise generation mechanisms. Railway operators and wheel manufacturers use this test to develop noise mitigation strategies and ensure compliance with environmental noise directives. Accreditation validates that testing facilities can accurately measure and report wheel-generated noise for European railway standardization and regulatory compliance.
What it measures
- Squeal frequency content and magnitude
- Curve-induced noise characteristics
- Sound pressure levels in critical frequency bands
- Noise generation under specific track geometry conditions
- Wheel surface roughness correlation with noise
