Effective Acoustic Dampening: Our wedge-shaped soundproofing foam is designed with sharp grooves that maximize the reduction of contact area between units. This forces the sound waves to take a multi-spiral path during propagation, undergoing multiple reflections and scattering with the contact surfaces to absorb more acoustic energy. It is great for controlling excess sound reverberations indoors.
Quick Recovery & Expansion: The uniqueness of our acoustic foam lies in its ability to rapidly reinflate to its original shape even after prolonged compression in sealed packaging. It only takes 3-5 hours of ventilation for the foam to fully recover, making it far more convenient than other soundproofing foams. PLEASE NOTE: If it fails to restore its shape, soaking the sound foam in water for one minute then wringing the water out and using a hair dryer or letting it air/sun dry.
