Witryna14 wrz 2024 · Impact Insulation Class (IIC) is a sound rating that measures the impact generated noise that is transmitted through a floor/ceiling or roof system and into the room below. These impacts can be caused by footsteps, falls, chair scrapes, fallen objects, or weather impact.
STC stands for sound transmission class. This is the most common sound rating used in North America for determining airborne sound transmission loss between 125 Hz and 4,000 Hz. This range covers the majority of common noises we hear including speech, television, music, dogs barking, and other similar … Zobacz więcej Because of this, a product can perform exceptionally well in one range, poorly in another, and still end up with a better STC rating than a competing product that may have performed better in a frequency range more … Zobacz więcej The GenieClips® RST are most commonly used on the ceiling to improve the IIC rating, while GenieMat® RST rubber underlayment is most commonly used on the floor to improve the IIC rating.
