Resilient materials are not very dense, nor thick. The material will absorb and reduce soundwaves at mid and high frequency. Most floor underlays are resilient materials, making them the most effective against impact sounds. What type of flooring over your underlay?įor Impact Noise: Use resilient underlayment.To block airborne noise or to deaden impact noise?.To consider the right soundproof floor underlay for you, it is important to define the followings: Generally an expected Delta IIC is 21 for a resilient material like foam, fiber or cork. This is flattering for an underlayment’s advertisement but not explicit of its sound insulation performance. A “strong” floor assembly means a better STC and IIC rating. Those lab tests generally use floor assemblies that are “under steroid”.
The delta IIC doesn’t depend on the floor assembly used during the manufacturer’s lab tests. This test gives away the acoustic performance of the underlayment alone. The difference of IIC between 1) and 2) is the Delta IIC. Take the same concrete subfloor WITH underlayment.Take a bare concrete subfloor with NO underlayment.Take the time to picture the two following steps : It’s legitimate to ask ourselves, what is the pure performance of the underlayment alone. You might have understood that the floor assembly plays a major role in inflating the value of STC and IIC. Modern building codes generally require an IIC rating of 50. The higher the IIC value, the better the material dissipates impact noises. In the receiving room, the sound levels emitted by the tapping machine are measured and then translated into a IIC rating. It is determined in labs using a tapping machine in one room. Said simply, the IIC is an equivalent of STC, but for impact sounds. IIC stands for Impact Insulation Class (IIC). That’s the main reason why you can still hear hammer strikes from your neighbor, while you can’t hear him talking. Have you ever bounced a basketball or ran like crazy on a wood floor? At impact the ball, or footsteps, create a soundwave not only travelling through the air (as an airborne sound) but also travelling through the structure of the house. Although not perfect, the STC is a good way to assess how much a material can block airborne sounds.

STC rating conceptīuilding code requires wall or floor assemblies to achieve up to a STC rating of 50. The bigger the loss intensity, the better the material at noise reduction, thus a higher STC rating. The material is used in the wall or floor that separates both rooms. This consists in measuring the loss in sound intensity (in deciBel) between two rooms. It assesses how much a material can reduce airborne noise. STC rating is a standard measurement determined in labs. Soundproof underlays always display those 3 letters: STC.

TV sounds, conversations, or the sound of a coffee machine are examples of airborne sounds.

There’s a famous horror movie quote: “In Space, no one can hear you scream”. In the empty space for instance, no sound can be heard. Sound is a mechanical wave that needs physical matter (air) to travel. Airborne noise is the term used for sounds that move through air.
