✦ Synopsis

Experiments on the noise-reduction achieved by acoustical barriers have been carried out on a scale model for a straight line source. The latter consisted of incoherent source elements, consisting of small air jets. For the attenuation by a single barrier the simple function AL = -(10 + 6 log N) dB was found to fit the experimental data. The influence of different barrier shapes was also measured.

Noise reduction by an acoustic barrier of a straight line source is examined with the aid of scale model experiments. The line source used in these experiments is an incoherent line source mechanically radiating broad band noise. From the experimental results a curve can be deduced which shows a rel
