Sound Advisor®
Flooring and installation choices can make a difference in how sound travels between spaces. Sound Advisor® helps you compare those differences before making a flooring decision.
Hear the Difference
Choose your floor assembly and flooring type, compare llC ratings, and listen to test audio to hear the difference for yourself.
How is Sound Measured?
Three common ratings measure different types of sound absorption and transmission.
Impact Insulation Class
Measures how much impact sound from the floor above transfers to the space below. Think footsteps, dropped objects or furniture moving across the floor. IIC is the most relevant sound test for flooring.
Noise Reduction Coefficient
Measures how much sound a material absorbs within a space.
Sound Transmission Class
Measures how much airborne sound transfers through a floor/ceiling or wall assembly. Think telivision, music or appliances. Flooring has little impact on STC testing.
