Improve in-cabin vehicle acoustics using active noise cancellation technology

The sound of next-generation vehicles will no longer be dominated by the powertrain but largely influenced by road and wind noise. Contrary to adding sound to the vehicle, there are many situations where the sound of silence may be preferred.

Active noise cancellation technology helps improve in-cabin comfort by reducing the perceived level of powertrain and road noise.

The Siemens broadband active noise cancellation (ANC) solution has been designed to tackle engine noise and road noise. It helps conventional and electric automakers to reduce unwanted noise sources and improve overall vehicle acoustics and the driver experience.

Leverage vehicle active noise cancellation and gain maximum advantage from the move toward software-based acoustics

Relying on years of NVH, acoustic, and engineering expertise, Siemens has developed a vehicle active noise cancellation solution that reduces the dependence on passive techniques while using an all-digital automotive audio bus.

Learn how vehicle active noise control can set manufacturers apart in the marketplace by offering consumers unique value propositions.

ANC technology – the next frontier in vehicle noise management

The availability of powerful processors and sensors at an affordable cost, software algorithms, modern tuning techniques for sensor placement, and the market trend towards rapid integration of these components in the vehicle has accelerated the commercial adoption of ANC technology.

Learn how automakers can offer new features while keeping the vehicle’s weight low. Active methods play a vital role in reducing NVH and thereby improving the in-cabin experience. Key aspects of ANC technology are explored further emphasizing topics to consider for automakers while adding noise management features in the car.

Enhance the acoustic feedback to the driver on the vehicle dynamics using active sound design

Active sound design is another technological approach to vehicle sound enhancement. It helps to improve the driver’s experience by giving acoustic feedback on the vehicle’s performance and ensuring the safety of other road users by emitting exterior warning sounds. Active sound design and active noise cancellation technology typically run in parallel on the same embedded system. Therefore, manufacturers can simultaneously reduce the perception of in-cabin noise while enhancing the acoustic feedback to the driver on the vehicle dynamics.

This white paper describes the active sound design engineering process and how to add meaningful sounds to the vehicle – both inside and out - that meet both brand sound and engineering targets.
