AbstractThe change in flanking sound insulation due to adding a floor 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. This paper summarises results presented elsewhere [1,2]. Floor vibration mappings reveal that a topping will change not only the power injected but also the propagation losses 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.
