Outdoor Warning Systems Guide

Abstract

A practical guide has been developed to aid public officials in determining the requirements for outdoor warning systems. The guide is a replacement for DCPA Federal Guide, Part E, Chapter 1, Appendix 3, 'Principles of Sound and Their Application to Outdoor Warning Systems,' first issued in December 1966. The new guide is based upon a survey of the current literature, and upon discussions with Civil Preparedness personnel and vendors. No experimental work has been performed. The guide, included as Sec. 3 of this report, covers in a simplified form the principles of sound, outdoor warning systems and devices, propagation and detection of sound out of doors, avoiding hazardous noise exposures, and warning system planning, testing, and use. Technical data in support of the Guide are given in Sec. 4 of this report, and conclusions and recommendations based upon the study are provided in Sec. 5.
