Sound levels and shadow zones behind barriers in Florida MacDonald, J et al

By: Publication details: Transportation Research Record, 2004Description: nr 1880, s. 158-64Subject(s): Bibl.nr: VTI P8167:1880; VTI P8169:2004Location: Abstract: A description is given of new results based on measurements of 19 noise barriers in the state of Florida and the innovative techniques used during data analysis. This work is a continuation of an ongoing study of noise barrier effectiveness in Florida. A new empirical method was developed to estimate the length of shadow zones behind highway noise barriers. This new method can lead to more effective design of future highway noise barriers. The method required an estimate of location and strength of a simulated background source to determine a more realistic edge of the shadow zone. This work also produced custom software that estimates and graphs the formation of shadow zones behind barriers, given readily available site information.
