EFFECTIVENESS OF TRAFFIC NOISE BARRIER ON I 471 IN CAMPBELL COUNTY, KENTUCKY. INTERIM REPORT

The objective of this study is to evaluate the effectiveness of the traffic noise barrier on I 471 in Campbell County, Kentucky. Since the barrier construction coincided with construction of I 471, it was necessary to predict noise levels that would exist if no barrier were present by utilizing the FHWA STAMINA 2.0 computer model. This was compared to actual noise level measurements at the barrier site in order to determine the barrier insertion loss. After calibration of the STAMINA 2.0 model, initial field measurements were taken at receiver locations throughout the barrier site. The average insertion loss in Leq was found to be 7.0 dBA, ranging fron 3.5 dBA to 13.0 dBA. The average insertion loss in L10 was found to be 8.2 dBA, ranging from 5.0 dBA to 14.3 dBA. A questionnaire to be used in a community perception survey was developed. The survey will be distributed and the results summarized in the final report. (Author)
