• Abstract:
  This report details work of a continuing project investigating the effectiveness of in-situ in the state of Florida. Data collection started on November 30, 2000 and the last site was visited in May, 2002. Broadband (A-weighted) and 1/3 octave band sound levels were measured at locations above the barrier, behind the barrier and in some cases at the end of the barrier for purposes of direct insertion loss estimation. Measurement results from these sites were used to evaluate the effectiveness of the barrier, and the TNM, STAMINA 2.0 (using older national reference energy mean emission levels), and STAMINA 2.1 (with Florida specific reference energy mean emission levels) computer prediction models. Additionally, work was begun to determine the meteorological effects on barrier performance and estimation techniques to determine length of the shadow zones created behind highway noise barriers.
