Development of a prediction model for indoor rolling noise

This work presents a prediction model for rolling noise in multi-story buildings, such as that generated by delivery trolley. Until now, mechanical excitation buildings has been limited to impact sources the tapping machine. Rolling models have outdoor trains and automotive vehicles. The presented here is able represent physical phenomena unique indoor noise, taking into account influencing factors roughness of wheel floor, material geometric properties velocity trolley, load on may be used tool investigate how different flooring systems (including multi-layer systems) respond excitation, purpose developing building solutions which are better equipped combat this kind source.
