Description
Summary:A detailed investigation of the noise soundscape resulting from traffic on a 3-mile segment of Nebraska Highway 2 prior to resurfacing work was undertaken by the students enrolled in the Acoustics Program at Columbia College, Chicago. Noise data were acquired at six different locations using established protocols and included daytime and nighttime conditions. The test data were compared to the predictions from an outdoor noise propagation computer model and the results were found to be within ±2 dB for all locations under consideration. The computer model was then used to assess expected noise conditions under various concrete and asphalt scenarios for resurfacing. Data show that reductions of up to 6 dB in the overall noise levels may be achievable depending on the choice for the surface of the roadway.
