Synopsis:

The subject focuses on the issue of noise generation and propagation in rail transport. As part of the theoretical part, students will gain knowledge about the problem of noise, its localization and propagation, with an emphasis on rail transport. They will be introduced to both basic and innovative applications of anti-noise measures, both on the vehicle side and on the infrastructure side, and learn to implement their optimal combination to achieve the best possible effect. The practical part of the subject is field measurement, where the dominant sources of noise on a real moving vehicle will be located with the help of a modern acoustic camera.

Requirements:
