Pajisjet për zvogëlimin e zhurmës së trafikut rrugor - Metoda e provës për përcaktimin e performancës akustike - Pjesa 2: Karakteristikat e brendshme të izolimit të tingullit në vijë ajrore në kushtet e fushës zonore të shpërndarë

Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 2: Intrinsic characteristics of airborne sound insulation under diffuse sound field conditions

Scope

This European Standard specifies the laboratory method for measuring the airborne sound insulation performance of road traffic noise reducing devices in reverberant conditions. It covers the assessment of the intrinsic performance of barriers that can reasonably be assembled inside the testing facility described in EN ISO 10140-2 and EN ISO 10140-4.
This method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed on roads in non-reverberant conditions.
