We humans take in the world via a variety of senses. Interaction phenomena are expected in the context of sound and vibration. In fact, the evaluation of acoustical comfort in a vehicle cannot be achieved with consideration of only the airborne noise. A passenger must be regarded as part of a vibro-acoustic system in which coupling with the vehicle occurs via contact points of the steering wheel, seat, floor panel and pedals. Within this context and quiet vehicles with low interior sound pressure levels, vibrations can become more important. The impact of combined sound and vibration stimuli on subjective evaluations has not yet been fully clarified. This article explores different test situations and their influence on measured results. Test subjects were asked to evaluate sound, or vibration, or both, with respect to their quality in different test situations. Different test settings were considered - real vehicle drive, noise and vibration reproduction in a driving simulator, and noise playback in a listening room. The tests provided information about the interaction of sound and vibration, and about the importance of other aspects such as situational awareness and interactivity.
