Prediction of Highway Construction Noise Levelsby William Bowlby, Vanderbilt Univ, Nashville, TN, USA,

Abstract: A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically represented as points, lines and areas, and noise barrier attenuation may also be analyzed. Built into the model and accompanying computer program is a data base for over fifty types of construction equipment and operations. Use of the interactive computer program is illustrated through an example problem. While use of the model is not required, FHWA regulations do mandate that highway construction noise be addressed during the development of Federal-aid highway projects. The model and program may therefore be used by highway noise control engineers for environmental impact assessment and for design of noise abatement measures.
