OUTDOOR WARNING SYSTEMS GUIDE <br />Abstract <br />This practical guide has been developed to aid public officials in <br />determining the requirements for outdoor warning systems. <br />The guide covers, in a simplified form, the principles of sound, <br />outdoor warning systems and devices, propagation and detection <br />of sound out of doors, avoiding hazardous noise exposures, and <br />warning system planning, testing, and use. <br />The guide is adapted from Report No. 4100, Bolt Beranek and <br />Newman Incorporated, produced under Contract No. DCPA- 01 -78 -C -0329, <br />Work Unit No. 2234E. Report No. 4100 is based upon a survey of <br />the current literature on the subject, and upon discussions with <br />Civil Preparedness personnel and vendors. No experimental work <br />has been performed. <br />The guide is a replacement for Federal Guide, Part E. Chapter 1, <br />Appendix 3, "Principles of Sound and Their Application to Out- <br />door Warning Systems," and Part E, Chapter 1, Appendix 4, Annex <br />1, "General Instructions for Determining Warning Coverage," <br />both published in December 1966. <br />ii <br />10 <br />CPG 1 -17 <br />
