CAE's Floating Barrier System Control Low Frequencies

Low frequency road noise is a strong contributor to driver fatigue. Using CAE's floating barrier system effectively stops the noise from entering the cabin.

Unlike vibration dampers which convert vibration energy into low level heat, floating barriers place a physical barrier in the path of sound to stop it. One layer of a floor barrier outperforms over 4 layers of a vibration damper.

VB-3 and VB-4 are important products in sound control design. Contact a specialist at CAE to discuss the proper material selection for your application.

VB-3 is a multilayered composite material, which provides a shock absorbing, noise penetration barrier and thermal insulation. The isolation layer is constructed of a closed cell reinforced neoprene which decouples the floating lead septum from the vibrating source structure (floorboards etc.).

VB-4 is a composite material with a flexible, loaded vinyl mass barrier, and a foam decoupling layer which reduces road noise by impeding the passage of soundwaves.

VB-TSM is the perfect product for severe noise control problems. It is especially effective for RV and marine engine compartments and generator housings. VB-TSM is a unique, high performance composite material incorporating two layers of acoustical foam, a loaded vinyl barrier and an aluminized mylar thermally reflective skin.
