Impact isolation class
WitrynaHigh-Frequency Impact Insulation Class (HIIC): A single number rating used to evaluate the effectiveness of floor systems at reducing high-frequency impact sound transmission in a laboratory. Through years of data, it has become apparent that floor toppings and underlayments have a much greater effect on the high-frequency IIC …

Witryna15 sie 2024 · Impact sounds (impact isolation class - IIC) The airborne sound or noise arising from the impact of an object making direct contact with a surface. These sounds travel because the impact creates vibrations in the construction elements (e.g. wood joists and beams) that connect walls, floors and ceilings as part of the overall … WitrynaIIC stands for Impact Insulation Class. An IIC is a single number rating that describes the impact noise reduction provided by a floor/ceiling assembly when subjected to a standardized tapping machine and tested in a laboratory in accordance with ASTM Standard E492. 2. What are the requirements for IIC ratings in multi-family buildings.
WitrynaSTC (Sound Transmission Class) and IIC (Impact Isolation Class) are independent ratings that evaluate the level of sound a product can reduce or absorb. STC ratings represent a product’s ability to block sound from traveling through a wall, ceiling or floor. IIC measures a floor’s ability to absorb impact sound, like footsteps. For high ... WitrynaImpact insulation class (or IIC) is an integer-number rating of how well a building floor attenuates impact sounds, such as footsteps. A larger number means more attenuation. The scale, like the decibel scale for sound, is logarithmic.
