Measurement kit for
dynamic stifness testing
Samples of materials used for impact sound insulation in buildings
are investigated. Typically, these materials can be part of
floating floor constructions in dwellings, where they
traditionally have shown to be very useful for reducing noise
propagation. The performance of the floating floor directly
depends on the mechanical properties of the insulation layer, in
particular the dynamic stiffness, together with its mass per unit
area. Rigidity_MAA allows you to measure dynamic stiffness
according to STandard EN 29052-1.
Parameters
Dynamic stiffness according EN 29052-1 (1993) and loss factor
(half-power method)
