Automotive Audio - Simulation and Test

When designing infotainment systems lots of different variants need to be considered: Which is the best possible positioning of speakers within the interior and how many are needed? Which combination of speakers will work best? How will the car’s structure impact the sound? Will the interaction between loudspeaker and chassis cause any disturbances? And how will the sound be perceived inside of the car - especially at the occupant’s ears?

Our expertise for your product development - reliable simulations and precise measurements by Novicos

Numerical simulations will effectively guide your research and development processes and provide the answers you need - even at an early stage. We will help you virtually analyze and evaluate several scenarios, e.g. different combinations and positions of speakers. At later development stages numeric tools are the perfect solution for troubleshooting as well as for basic tuning – they will help you identify the sources of disturbances fast and precisely and enable you to optimize your infotainment system.

By combining simulation and test you will get reliable information on sound pressure distribution inside the car in relation to any relevant technical parameters, such as position and number of required speakers, using voids inside the chassis or vibro-acoustic interaction between loudspeakers and structure.

Our experts will be happy to discuss your specific case and offer advice on how to meet your challenges.
