DS DSEN SO 140-11 2005-JUN-28 Acoustcs - Measurement of sound nsulaton n buldngs and of buldng elements - Part 11 Laboratory measurements of the reducton of transmtted mpact sound by floor coverngs on lghtweght reference floors Replaced by DS DSEN SO 10140-3 DS DSEN SO 10140-4 DS DSEN SO 10140-5
This standard specifies a method for measuring the acoustic properties of floor coverings from the viewpoint of reducing impact sound transmission using the standard tapping machine. The purpose is to establish a method for determining the impact sound insulation of a floor covering under standard test conditions. In addition, methods are also introduced in informative annexes to simulate sources with strong components at low frequencies, such as human footsteps or children jumping.
