Three permanent noise monitors had increases in DNL levels ranging from +0.5 to +1.5. Five monitors had decreases ranging from 0.1 to 4.3. An increase of 3+ DNL represents a doubling/halving of the noise energy. The DNL (Day-Night Level) metric represents noise exposure events over a 24 hour period. The DNL metric approximates the response characteristics of sound to the human ear. The higher the number on the scale, the louder the sound. To account for human sensitivity to noise between the hours of 10 p.m. and 7 a.m., noise events occurring during these hours receive a penalty when the DNL is calculated. Each night time event is measured as if ten daytime events occurred. 75 Noise Monitoring Data 2nd Quarter 2016 Average DNL Years 2014-2016 2nd Quarter 2014 70 2nd Quarter 2015 2nd Quarter 2016 65 60 55 50 45 40 35 Site 1 Site 3 Site 5 Site 7 Site 8 Site 11 Site 12 Site 13
