Dispozitive pentru reducerea zgomotului din traficul rutier. Metoda de încercare pentru determinarea performanţei acustice. Partea 2: Caracteristici intrinseci ale izolaţiei la zgomote aeriene în condiţii de câmp acustic difuz
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.
