The dynamic stiffness measurement is to determine of elasticity of material used as vibroisolation performed by information about resonant frequency of testes system.
The tests are carried out by Dynamic stiffness test bench in accordance with:
EN 29052-1:2011 Acoustics - Determination of dynamic stiffness - Part 1: Materials used under floating floors in dwellings.
As part of the testing of the PM&VL7 research line, Flex&Robust connections, injections and layers were examined.
