'On higrtway= noise have concl6deo that truo'ks, especially cliesel pow,ercd,` are tho peak noise producers The noise level from 4 trucks traveling 5o mph is equivalent to 84 autos at 65 mph. Therefore, the noise from diesel trucks is used as the standard reference by both the U.S. and Cal fbrnia T)epartments of Transportation in determining :estimator, noise ° levels for highways and A c6mplete' study, of the State highways in Butte County was done by the California Department of Transportation in accor- dance with Section 65502(g) of the Government Code, From the j typical noise r E ,study was developed a graphic report slio��ing contour`s or noise levels between 45 and $5 decibels for grad'", elevated and depressed right-of-way conditions: 'Typical contours o for speed limits of ,a5 ,mph or less are shown 1A Figure , 5 and above 55 mop contours are shown in Figure 6 ;y The estimated { i -pa.cal noise contours depr-i the moa,i un- shielded and ftitl'ly eXposect-diesel. truck noise 6 dBA, This in , formation can also be used for cetermi.A ng noise contours for other right s: oto; way, in the county," including streets that are Virtually free from diesel truck traffic.
