Impact isolation class tests
Did you know?
WitrynaAn impact insulation class (IIC) is a standard rating of how well a building partition blocks impact sound or structure-borne noise. The test to determine the IIC rating of a partition evaluates and quantifies a partition’s resistance to the transmission of impact-generated vibrations from noise source to the receiving side of the partition. Witryna22 wrz 2011 · 1. One key requirement for a good unit test is that it is isolated. In practice, this means no unit test uses state from other tests or can be affected by state in …
Witryna20 lut 2024 · 5.3.1 Noise Reduction (NR) and Noise Isolation Class (NIC)— Describe the sound isolation found between two spaces. Noise reduction data are based on the space- and time averaged sound pressure levels meeting the requirements of 11.3 or A1.3 as required depending on the sound absorption, volume, and shape … WitrynaIIC (Impact Insulation Class) Ratings/Tests of Floor/Ceiling Assemblies. 1. What is an IIC test or rating? IIC 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 ...

WitrynaIIC stands for impact insulation class. Acoustic labs conduct the IIC test using a tapping machine with steel faced hammers. These hammers strike a test floor material generating sounds between 125 to 4,000 Hz. The impact creates vibrations that travel through the floor into the receiving side (the room below).
