FOOTFALL NOISE INSULATION TEST ON ACUSTIC SYSTEM 10 SPECIMENS IN ACCORDANCE WITH UNI EN ISO 140-7.A footfall noise insulation test was performed on ACUSTIC SYSTEM® 10 specimens in accordance with UNI EN ISO 140-7, using a 20 + 4 Bausta type floor and a levelling screed of about 7 cm. The indexes of footfall noise normalized levels were assessed for the tested product in three different experimental conditions corresponding to three different floating screed thicknesses. The im-provement in footfall sound insulation performance is given as the difference between the results of tests performed on experimental screeds and the result obtained by placing a tapping machine directly on the bare floor “L’n,w=L’n,0,w-L’n,w”. The whole system, made up of resilient footfall noise deadening material and floating screed, is considered by UNI EN ISO 140-8 (see par. 5.3.2.2) standards as equivalent to a floor covering assembly (see certificate 12C)
