Bibliography

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.

Committee

DevelopmentNote
To be read in conjunction with EN 1793-1, EN 1793-3, CEN/TS 1793-4, CEN/TS 1793-5, and EN 1793-6. (11/2012)
