In combination with the SoundSeat, the PreSense NVH simulator can be operated like a real vehicle. The user accelerates, brakes and shifts gears while the system adapts sounds and vibrations to the driving situation in real time. Shakers realize realistic steering wheel and seat vibrations while a large screen provides an overall visual impression of the driving situation.

Compared to headphone-only playback, authenticity is greatly enhanced when the NVH simulation is experienced in a realistic environment and while being interactively controlled. Instead of having to listen to prefabricated stimuli on an office chair in a listening studio, the test person sits as if in the vehicle and is allowed to influence the sound himself. The vibrations of the steering wheel and seat increase the immersion.

This context greatly increases the validity of the assessment. The goal is that the driver feels the same perception as in the real car. Even without interactive driving, the SoundSeat is also suitable for passive playback in a vehicle context, e.g. for assessing and comparing noise and vibration recordings or for quality control.
