Noise barrier

prefLabel
  • noise barrier
definition
  • Barriers for reducing the propagation of sound: they are widely used in industry and alongside roads and railways to shield receivers from noise sources. Barriers will not reduce the noise on the receivers side, but will increase it, unless the barrier is also covered in absorbing material.

Abstract from DBPedia
    A noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls. In the case of surface transportation noise, other methods of reducing the source noise intensity include encouraging the use of hybrid and electric vehicles, improving automobile aerodynamics and tire design, and choosing low-noise paving material. Extensive use of noise barriers began in the United States after noise regulations were introduced in the early 1970s.

    遮音壁(しゃおんへき)または防音壁(ぼうおんへき)(英: Noise barrier)とは、騒音を発生する施設から周辺の土地を守るために設置される壁である。遮音壁は特に道路、鉄道、工場など、騒音源自体を抑制・制限できない場面でよく使われる。 道路交通による騒音の場合、他の騒音抑制策として、ハイブリッドカーや電気自動車の奨励、車体の空気力学の改善、タイヤの設計改善、低騒音の舗装などがある。遮音壁は1970年代初期にアメリカ合衆国で騒音規制が施行されてから広く採用されるようになった。
