Abstract
the results of scaled acoustic laboratory experiments with noise barriers are reported. Short impulsive spherical sound wave with broad frequency spectrum is used as controllable sound source. Using spectral analysis the insertion loss spectral functions were calculated for experiments with different source-receiver positions. The results were rescaled to traffic barriers and for typical traffic noise spectrum the values of the traffic barrier efficiency (a single number rating) were estimated and the directivity diagrams obtained.
