Arden Hills 55+ Senior Housing Complex Traffic Noise Assessment <br />David Braslau Associates, Inc. Page 13 <br /> <br />3.2. Noise Model Predictions <br /> <br />Traffic noise predictions for Hwy 10 monitoring site are presented in Figure 3.2 for both the 6-7 AM <br />period (covered by nighttime standards) and the 4-5 PM period (covered by daytime standards). As can <br />be seen in the figure, monitored levels were considerably higher for the AM period than expected for a <br />speed of 55 mph. The levels are also higher during the PM period. Therefore, a speed of 65 mph has <br />been assumed for Hwy 10 with predicted levels shown in Figure 3.4 on page 14. <br /> <br /> <br /> <br />Figure 3.2 Predicted Noise Levels (dBA) with 55 MPH on Hwy 10 <br /> <br /> <br /> <br /> <br />
