Electric mobility

Rethinking vibroacoustics

Whether car, bike, yacht or air taxi: electric motors are quieter than combustion engines – but not silent. Their tonal, high-frequency noise components are often perceived as annoying by users. What's more: creaking, humming, whistling or howling from other noise sources are no longer masked and come to the fore in an unpleasant way. A coherent  product in line with new legislation and innovative mobility concepts is crucial for a positive user experience and thus for economic success.

New phenomena - new procedures

To derive concrete development goals for the overall system and for components, their interaction must be understood, simulated and evaluated.

This  is the recipe for success:

  • Understand customer expectations
  • Identify and optimize the operating conditions relevant to the user experience
  • Develop AVAS sounds that comply with differing local legislation
  • Use “Active Sound Design” to achieve a balance of physical and synthetic sounds suiting the brand

“Exciting sound design” vs. “too much science fiction”

  • Benchmarking
  • UX-based testing
  • Target sound definition

User-centric approach.

Interactive simulation.

Specific insights.

A comprehensive understanding of vibroacoustics

Our silent measurement technology in combination with specific and standardized analyses – including tonality – enables the evaluation of all vibroacoustic phenomena in e-mobility.

Understand your customers' expectations with our user-centric solutions and services such as jury testing and individual user studies.

Save prototypes by frontloading: Make the impact of operating strategies, design changes, AVAS sounds and active sound designs perceptible right from early development phases – with our interactive NVH simulator.
