Vehicle Acoustics - Noise, Vibration, Harshness

Targeted Design of the Vibration and Acoustics Behavior of Vehicles

Acquire a particular understanding for vehicle-specific acoustic effect mechanisms and learn to implement the respective remedies in a goal-oriented manner for existing problems.

Course Content

Comprehensive and holistic understanding of the entire vehicle system
Vehicle-specific acoustic effect mechanisms and remedies for existing problems
Practical transfer of knowledge with numerous application examples
Applying the learned knowledge in your own case study

Group of Participants
Engineers or technicians from the automotive or supplier industry with at least one year of relevant professional experience.

Motivation
The topic of acoustics is key for developing vehicles achieving high quality standards. The areas of noise, vibration and harshness are essential elements to create a targeted vibration and acoustics behavior.

Methodology
In five days of attendance, participants will gain a comprehensive understanding of automotive acoustics, which will be established through lectures. A deepening takes place by illuminating the industry perspective as well as the processing of a separate case study.

Further information regarding the certificate course "Vehicle Acoustics"

On the first day of the course the following topics will be taught:

  • Fundamentals of Vehicle Acoustics and introduction to sound field and sound energy parameters
  • Human perception of air-borne and structure-borne noise
  • Overview of sensors and PC-based measurement systems for data acquisition and signal analysis
  • Measurement rooms like anechoic chamber, reverberation room and aero-acoustic wind tunnel

On the second day of the course the following topics will be taught:

  • Prevailing regulations (interior and exterior noise)
  • Noise measurement procedures and mandatory noise limits
  • Characterisation of sound sources: engine, transmission, shafts and joints
  • Electro and hybrid powertrains: new acoustic challenges
  • Transfer of vibrations and radiation into the veh. interior
  • Analysis of noice sources and transfer

On the third day of the course the following topics will be taught:

  • Tyre/road noise (generation mechanisms, measurement procedures and reduction measures)
  • Brake systems (generation mechanisms, measurement procedures, reduction measures and noise phenomena)
  • Task: Interior noise phenomenon (powertrain exited) to be reduced
  • Measurements (road/ bench tests)
  • Root cause analysis, reduction measure
