Berlin (Germany), January 14, 2026 – Acoustic measurements play a key role in the approval process and passenger comfort assessment of modern rail vehicles. Stadler Rail has recently carried out acoustic tests on its vehicles at its test center, using data acquisition technology from imc Test & Measurement in combination with GRAS measurement microphones.

The tests were performed directly on the vehicle under real operating conditions. The aim was to analyze noise emissions, verify compliance with applicable regulatory limits, and assess passenger comfort. Accurate acoustic data is essential for vehicle certification as well as for optimizing noise behavior during operation.

According to Stadler Rail, the combination of imc’s precise measurement systems and GRAS microphones enabled the reliable collection of high-quality data required for approval and vehicle optimization. The results support improved safety and enhanced ride comfort for passengers.
