Study on the Occurrence Conditions of Squeal Noise and High-frequency Noise in Railway Curved Sections

Last updated on 16 September 2025 11:15

Squealing (below 10 kHz) and high-frequency noise (above 10 kHz) can occur when trains pass through curved sections of track. Measurements of these noises were carried out on commercial lines to understand how they are generated. It was found that these noises vary from wheel to wheel, having large dispersion.
