The course is based on fundamental findings from European and national research projects:
1. Environmental Conditions
2. Physical basics
3. Measurement methods: Recording technology and procedures, data analysis, post-processing and digital acoustic procedures as well as digital video recording technology
4. Experimental methods: In-car, at the test site and on the acoustic roller dynamometer
5. Parameters influencing the exterior noise: Vehicle (car, truck) - drive train (transient engine operation) - tires (tractive force, contact force, slip, temperature) - driving condition (rolling, constant, accelerated) - road surface
6. Simulation methods for the exterior noise
7. Optimization of the overall system vehicle - tires - road surface
In the framework of the lecture, physical basics are introduced. The in-depth knowledge is based on the results of our own international research projects. The experimental and computational methods are discussed using practical examples.
