Acoustics. Method for the determination of dynamic stiffness. - Materials used under floating floors in dwellings not-for-sale BS 2782-9: Method 940B on1 Scope This part of ISO 9052 specifies the test method for determining the dynamic stiffness of resilient materials used under floating floors. Dynamic stiffness is one of the parameters that determine the sound insulation of such floors in dwellings. This part of ISO 9052 applies to the determination of dynamic stiffness per unit area of resilient materials with smooth surfaces (see clause 6) used in a continuous layer under floating floors in
