Perturbation The height increment that a noise barrier's input height is increased (perturbed up) or decreased (perturbed down) during the barrier design process.

This document reflects substantial improvements and changes in noise barrier design that have evolved since the original 1976 publication. This Handbook, which is accompanied by a videotape and a companion CD-ROM, addresses both acoustical and non-acoustical issues associated with highway noise barrier design. The objectives of this document and accompanying video and CD-ROM are to provide: (1) guidelines on how to design a highway noise barrier that fits with its surroundings and performs its intended acoustical and structural functions at reasonable life-cycle cost; and (2) a state-ofthe-art reference of common concepts, designs, materials, and installation techniques for the professional highway engineer, the acoustical and design engineers and planners, and the nonprofessional community participant. This handbook may also be used as a guide for other applications such as noise barriers used to attenuate noise from rail lines, as well as noise from other sources which are not necessarily found in transportation.
