Abstract

This research will develop a videotape that discusses the principles of sound and highway traffic noise. Information will be presented simply in a nontechnical manner so that the videotape can be used as an educational tool for the general public. It will also be used to train highway traffic noise analysts.

Abstract

This videotape, approximately 43 minutes in length, is an educational tool that illustrates many different aspects of highway noise barriers. The videotape covers (1) basic acoustics; (2) barrier performance; (3) types of barriers; (4) wall barrier materials; (5) barrier maintenance concerns; and (6) barrier safety concerns.
