Impact noise travels through the building structure when footsteps, rolling objects, or dropped items strike the floor. Acoustic underlayments may use rubber, cork, foam, fiber, composite sheets, or poured materials. They are installed beneath tile, resilient flooring, engineered wood, laminate, or other approved finishes. Published sound ratings apply to tested assemblies, not the underlayment by itself. Concrete thickness, ceilings, insulation, floor covering, perimeter isolation, and installation details affect actual results. The underlayment must also support expected rolling loads, indentation, adhesive, tile, and moisture conditions. Selecting a soft product solely for a high advertised rating can create flooring-performance problems.
Key considerations
- commercial acoustic underlayment, flooring sound control, impact noise reduction flooring
- acoustic underlayment, sound control flooring, commercial underlayment
- impact-noise reduction, sound control, load support
- resilient layer, tested assemblies, perimeter isolation
