Noise strongly influences both passenger comfort and public acceptance of rail vehicles. But how can exterior and interior noise be measured reliably, evaluated in compliance with standards, and used effectively in development and approval processes?

In this webinar, you will learn how modern measurement technology and software support the entire process – from standardized exterior noise testing to objective speech intelligibility assessment in passenger compartments. Discover practical strategies to reduce noise emissions, improve comfort, and streamline approval testing.

What you’ll learn:

• Conducting exterior noise measurements on rail vehicles in compliance with ISO 3095
• Implementing interior noise measurements according to ISO 3381 in a practical way
• Correct evaluation of key acoustic metrics (LAeq, LAFmax, LCpeak, frequency analyses) for comfort and safety assessments
• Selecting microphone positions in passenger compartments to ensure reproducible results
• Assessing passenger comfort based on acoustic parameters
• Objective evaluation of speech intelligibility using the STI / STIPA method in accordance with EN 60268-16
• Understanding the role of the signal-to-noise ratio (SNR) in speech transmission and how to measure it correctly
• Developing practical measurement strategies for type approval, certification, and modernization projects
