GB/T 19889.8-2006 "Acoustics - Measurement of sound insulation in buildings and of building elements - Part 8: Laboratory measurement of the reduction of transmitted impact noise by floor coverings on a heavyweight standard floor" specifies a method for measuring the improvement effect of floor coverings (such as carpets, floating floors) laid on a heavyweight standard floor under standard laboratory conditions. This method calculates the improvement amount by comparing the normalized impact sound pressure levels of the floor before and after the installation of the covering, and is used to evaluate the performance of covering materials in reducing impact noise.
