The most common reason to acoustically treat a floor is when impact noises like footfall and other vibrational noises become bothersome for people in the floor below. The solution for this is to create what is commonly referred to a ‘floating floor' using acoustic underlayment. Acoustic underlayments may be installed under many types of materials, including: engineered wood, hardwood, laminate, LVT (luxury vinyl tile), concrete, carpet and tile.
