Impact isolation class tests
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. The IIC is derived from ASTM method E989, which in turn uses a tapping machine specified in ASTM method E492. WitrynaImpact Insulation Class (IIC) is an acoustical rating used to quantify impact sound absorption and vibration isolation of floor and ceiling assemblies to des...

The two standard methods for rating the impact sound insulation of building components (ISO 717-2 [1] and ASTM E989 [2]) produce Ln,w (normalized … WitrynaIn response to complaints about structure-borne noise, in-situ floor impact isolation testing was conducted of a gym floor. The gym was located on the ground floor of a multi-storey residential apartment building. ... A Norsonic Nor140 Class 1 Precision Sound Analyser (serial # 1405077) was mounted on a
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. 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 …

Based on over 10 years of experience in conducting hundreds of tests on different floor finishes, acoustic underlays, concrete slabs and ceiling constructions, this papers provides a basis to ...
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).
WitrynaDefinitions: Impact Insulation Class (sometimes referred to as Impact Isolation Class) measures a floor/ceiling assembly’s resistance to the transmission of structure-borne or impact noise. IIC Strength: Helps to rate structure-borne noise such as footfall, a chair dragging on the floor, or other realistic sounds in a single number. shapes planning eyfsWitrynaAn impact insulation class (IIC) is a standard rating of how well a building partition blocks impact sound or structure-borne noise.
