Acoustics. Laboratory measurement of the reduction of transmitted impact noise by floor coverings on a small floor mock-up - Heavyweight compact floor Ingestion-build-81500 The direct1 Scope This part of ISO 16251 specifies a laboratory measurement method to determine the improvement of impact sound insulation by a floor covering when laid on a standard concrete floor mock up and excited by a standard tapping machine. The method is restricted to soft, flexible floor coverings, which transmit impact sound mainly locally into the floor, i. e. through the area close to the points of excitation, so that the size of the flooring
