NVH & Acoustics

NVH & Acoustics for Automotive Performance

The NVH and acoustic performance of a vehicle strongly impacts the driving experience and hence the perception of quality. Impacted by regulations and low-emission and zero-emission strategies, car manufacturers and suppliers seek solutions to design for optimal NVH comfort to adhere to their brand identity.

The integrated NVH and Acoustic solutions of Siemens Digital Industries Software are designed for combining simulation and test. They enable you to analyze the root cause of noise and vibration problems, optimize vehicles to improve brand image, and increase the perception of quality. Our tools and services help you design correctly from the start and prevent costly redesign later in the vehicle development cycle.

A vehicle’s noise and vibration behavior primarily influences comfort and the perception of quality. Excessive or unpleasant vibrations and sound affects the product’s brand image. The pressure on NVH engineering is constantly increasing. While legislation and regulation tightens, the automotive industry is confronted with a renewed need to address particular NVH challenges on component, subsystem, and full-vehicle level.

To design for premium NVH and acoustic quality, an integrated approach is required. Whether dealing with interior or exterior acoustics, intake or exhaust noise, engine acoustics, brake noise, noises from auxiliaries such as HVAC, batteries or inverters, or noise related to system integration, Siemens Digital Industries Software provides solutions for all stages of the development process. By combining simulation and test, our solutions help you to gain insights in how to reduce noise and vibrations, assess systems interactions and their influence on other performances such as fuel consumption, passenger comfort, and drivability, while striking an excellent balance between cost-efficiency, weight, and performance.
