| Abstract | This paper examines the effectiveness of toppings to control direct and flanking paths for an impact source placed on a wood-I joist floor. The change in flanking sound insulation due to adding a topping is shown to be different for paths where energy propagates perpendicular to the joists, compared to those where energy propagates parallel to the joists. Floor vibration mappings reveal that a topping will change not only the power injected but also the propagationlosses across the floor. The most effective toppings reduce input power and increase propagation losses relative to the bare floor. One type of topping exhibits significant improvement in the flanking sound insulation in one direction and a significant worsening in the other. The results are used to establish the basis for a semi-empirical model for flanking transmission in structures with very high internal losses. |
