TY - JOUR AU - Halliwell, R.E. PY - 1982/07/01 Y2 - 2024/03/28 TI - Field performance of parallel barriers JF - Canadian Acoustics JA - Canadian Acoustics VL - 10 IS - 3 SE - Technical Articles DO - UR - https://jcaa.caa-aca.ca/index.php/jcaa/article/view/486 SP - 9-18 AB - 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. ER -
