Vehicle acoustics and NVH

Simulate and measure NVH

We are your partner for acoustics in vehicles and NVH - Noise, Vibration and Harshness and accompany you through the new challenges in acoustics:

The elimination of the combustion engine also eliminates its masking of the overall noise.
Alternative mobility concepts are changing users' requirements in terms of background noise.
Innovative concepts and materials create conflicting goals.
New legal requirements for exterior noise must be met.

Troubleshooting inacoustics

System understanding for solution orientation

Target curve missed? Unintended vibrations shortly before SOP? Customer complaints from series production? We get you to the solution quickly and cost-effectively and support you in understanding the interrelationships so that such NVH problems can be avoided in the future.

NVH design in the V-process

Suitable solutions in every phase of development

From idea to SOP: Consider NVH characteristics throughout the development process to meet requirements and prevent troubleshooting. On component, system or complete vehicle level: We offer the appropriate method in the design, implementation and validation of your system.

Understanding vehicle acoustics and NVH

From the source to the receiver

Each NVH phenomenon can be described by the source, the transfer path and the receiver. By correlation and coupling of these levels we realize a valid description.

Source

Whether drive components, tire-road contact, wind noise or auxiliary units - the sources of various vehicle noises are diverse and dependent on boundary conditions. We work with you to develop the right solution in the test bench or simulation model (1D, FEM, CFD).

Transfer path

With the right methods, you can influence the NVH properties in a targeted manner. We analyze natural vibration shapes or transfer paths (TPA) for you experimentally and/or simulation-based. Subsequently, we develop solutions such as the optimization of topology or topography, absorbers, bearings, damping or attenuation systems.

Receiver

Vehicle occupants perceive sounds and vibrations in the vehicle as receivers. Therefore, an evaluation adapted to human perception is required. With psychoacoustic quantities, head-related transfer functions, listening tests or empirical perception models, a wide variety of approaches are available - we will be happy to support you.

AVAS and sound design

Legal requirements and brand identity

Vehicle sound is more than just a legal requirement. Use sound design to identify with your brand and build customer loyalty. The sound quality is influenced by the loudspeaker design, both inside and outside. Take advantage of this potential - contact us!
