Abstract

A method to measure the impact sound reduction at a compact measurement setup (COMET) is developed at the Physikalisch-Technische Bundesanstalt. This paper presents the setup and the test procedure with respect to a physical model of impact sound reduction for locally reacting floor coverings. The impact sound reductions of many floor coverings obtained at different test facilities according to ISO 10140 and obtained at different COMETs are compared. Under consideration of the standard uncertainties, an alternative procedure to calculate the impact sound reduction at the COMET is proposed which is different to the procedure in the current version of the standard describing the COMET (ISO/DIS 16251-1).
