Sound Trap is an engineered add-on solution for reducing noise in automotive cast aluminum parts. As a Constrained Layer Damping material, Sound Trap provides noise, vibration and harshness (NVH) performance through constrained layer damping. This sound damping material is typically offered as a pre-cut shape to conform to specific features of the casting.
With multiple applications, Sound Trap has proven to be highly effective for engine temperature applications such as cast aluminum oil pans and transmission housings. When mechanically fastened, Sound Trap is also suitable for oily or painted metals.
