註釋A description of motor vehicle noise sources and the potential for their control is provided. The report presents an overview of the suggested noise prediction methodology, which is a four step process that includes approximating noise impacts using a nomograph procedure to determine noise levels associated with given traffic and site characteristics; refining these predictions by more accurate representation of design parameters and use of a computer program that is able to plot as well as calculate noise impact; introducing appropriate noise-control options and evaluate them, using a noise barrier nomograph solution; lastly, selected options are fully evaluated using the computer program.
