The subject introduces students to the principle of noise measurement in the field with a focus on modern methods of locating noise sources in rail transport on a real passing vehicle.

As part of the practical part of the course, field measurements will be carried out using a modern device - an acoustic camera, which enables the display of the measured acoustic signal in the video camera image, or sound level meter be used. Students will learn to operate this device as part of the practical part. As part of post-processing, the student will perform a thorough analysis of the frequency range of the signal. Based on the performed frequency analysis, the student will determine which noise sources can be identified as significant and which can be neglected. At the end, an optimal anti-noise measure will be proposed.


There are no requirements.
