Due to its dimensions, a passenger cell produces rapid reflections which are not evaluated separately by the brain but rather as an energy increase of direct sound. The acoustics in the vehicle are therefore perceived as very dry and differ considerably from the acoustics usually found in the living room.
Vehicle acoustics can be made more similar to living room acoustics by adding artificial reflections. Three fixed settings can be selected: Concert hall, jazz club and cathedral. It is also possible to vary the parameters room size and reflection proportion proportion in seven steps thus adapting them to requirements.
