Acoustical Underlayment

Acoustical underlayment—which is distinct from standard flooring underlayment—helps prevent sound transmission through a floor/ceiling assembly and is especially valuable in multifamily housing. To achieve adequate sound isolation between upper and lower floors, the entire assembly should have both a sound transmission class (STC) rating and an impact insulation class (IIC) rating of 65–75. STC measures sound isolation at human speech frequencies, while IIC measures the assembly's ability to block footsteps and similar sounds.
