Field performance of parallel barriers

R.E. Halliwell


The behaviour of single highway noise barriers is fairly well understood, but little attention has been given to possible interactions when two barriers are built parallel to each other. A series of measurements on two barriers along Highway 417 suggest that the effects of any interactions are small if they exist at all.
