AbstractASTM and ISO impact sound tests use the same standardized tapping machine and are essentially the same. Four possible metrics, described below, are available for rating the effectiveness of the floor systems3,4. These metrics are or can be used to evaluate floor coverings or toppings that may be placed on concrete slabs or on lightweight joist floors. Correlations among the metrics are poor and numerical differences can be very large. Data collected in the NRC laboratory over several years are used to illustrate the problems facing the standards-writing committees.
