Automotive floor carpets are mainly effective to reduce noise radiated from the vibrating panel. Recently, the floor carpet is considered for reducing the vibration on the panel. This paper discusses the effect of attaching floor carpet on vibration and noise characteristics of a flat panel experimentally. As a result, it is suggested that the floor carpet reduces the out-plane vibration and gives the same effect as a viscous damping. We propose a FE modeling technique for the panel vibration including the effect of floor carpet based on the experimental discussions.
