Chapter 1 is devoted to <br />Fundamentals of Sound. This includes acoustic terminology, basic relationships <br />of sound, outdoor sound transmission, and a brief review of certain aspects of <br />man response to noise. Chapter 2 presents noise data of automobiles and truckt <br />s individual discrete sound sources', reviews brieflj► the principal components <br />of truck noise, places autos and trucks into the context of moving sound sources, <br />and introduces a statistical descriptor of highway noise. Chapter 3 is co n�ersed <br />with instrumentation and techniques for making outdoor noise measurement>;. <br />Chapter 4 is devoted to the basic features of highway noise prediction ucl-'Ip, <br />the NCHRP Report 117 and TSC procedures. Chapter 5 include discussiror, 04 the <br />noise abaLement treatments that are availa'6re-'for noise control, both .it the <br />highway and off the highway.
