Railway Brake Disc Acoustic Emissions Testing

This test method evaluates the acoustic emissions generated by railway brake disc and pad/block interactions under controlled conditions. It measures noise characteristics produced during braking events to assess the potential for noise disturbance in railway operations. The test is critical for railway operators and brake component manufacturers seeking to comply with noise regulations and ensure passenger comfort. Accreditation is essential to provide independent, standardized verification that brake systems meet acoustic performance requirements across European rail networks.

What it measures

  • Sound pressure levels during brake pad-disc contact
  • Frequency spectrum of brake-induced noise
  • Peak noise emissions under defined braking scenarios
  • Acoustic performance consistency across brake cycles
  • Compliance with European noise limits
