A simplified method to determine impact sound improvement on light-weight floors (NT TR 488)

NT TR 488

  • It is well known that the impact sound improvement for floor coverings on lightweight floors is very different from that on heavy concrete slabs. Most laboratories have only one test opening and it is expensive to change floors. Thus it would be preferable if it were possible to use a simpler test procedure. In this paper such a procedure is outlined and discussed.
