WitrynaImpact Insulation Class (IIC), the single-number rating for evaluating the impact noise insulation of a floor-ceiling assembly, and the associated field testing ratings, are unsatisfactory because they do not have strong correlation with subjective reaction nor provide suitable detailed information for evaluation or design of floor-ceiling assemblies. Witryna11 sty 2024 · Impact Insulation Class (IIC) is a rating of how well a floor/ceiling assembly attenuates structure borne sound. The IIC number is roughly the reduction in decibels that a partition creates in the 100 Hz to 3,150 Hz range when tapped by the testing machine. The easiest way to achieve the required IIC rating of 50 is to use … Witryna5 kwi 2024 · The Impact Insulation Class (IIC) is a rating system used to determine a floorcovering’s ability to block impact sounds from traveling to the unit below.
