Highway Noise; a Design Guide for Highway Engineers


Book Description

Various methods of assessing noise, loudness, and noise annoyance are reviewed and explained; sources, types, and intensities of traffic noise are noted; typical means of abatement and attenuation are described; design criteria for various land uses ranging from low-density to industrial are suggested and compared with the results of previous BBN and British systems for predicting annoyance and complaint; and a design guide for predicting traffic noise, capable of being programmed for batch and on-line computer applications, is presented in form suitable for use as a working tool. A flow diagram describes the interrelationships of elements in the traffic noise prediction methodology, and each element is discussed in detail in the text. The text is presented of a tape recording that takes the listener through a series of traffic situations, with such variables as traffic distance, flow velocity, distance, outdoors and indoors, and presence or absence of absorbers and attenuators.
