Structure-Borne Sound in Floor Coverings
topic
Impact sound insulation testing of carpet and textile floor coverings measures reduction in normalised impact sound pressure level when a standardised tapping machine impact is applied to a test floor with and without floor covering, calculating impact sound improvement delta Lw in decibels across the 100 to 3150 hertz octave band spectrum.
Role
Quantifies the footfall noise reduction provided by carpet, underlay, and textile floor covering systems in multi-storey buildings, providing the delta Lw data used in building acoustic calculations to demonstrate compliance with building regulations governing impact sound transmission between floors.
