Perception of noise transmitted through barriers
The Journal of the Acoustical Society of America, 1976Perceived loudness of noise transmitted through barriers was scaled by human observers outdoors. Using the method of magnitude estimation, subjects compared the relative loudness of a narrow band of noise transmitted through barriers of different solidity.

A serpentine noise barrier wall containing abutting concrete panels wherein the end panels of the wall are seated on concrete pads and supported in an upright position by angle irons. Adjacent panels are joined together at the shared joint region by connector plates that are mounted in recesses formed in the adjacent panels and are drawn tightly in ...

Analysis of noise barrier overlap gaps
The Journal of the Acoustical Society of America, 2002Sound propagation through the gap produced by two parallel vertical barriers with overlapped ends is formulated for traffic noise sources. The analysis identifies both source and receiver regions according to the mechanisms that influence noise propagation in the vicinity of an overlap gap.

Selection of Noise Barrier Material
Transportation Research Record: Journal of the Transportation Research Board, 2001Because of the large capital expenditures required to construct or replace a noise barrier, it is important for designers to have the information necessary to make rational choices among the materials available. Designers face difficulties, however.

Noise barriers with reactive surfaces
Applied Acoustics, 1998Abstract The boundary element numerical modelling method is used to study the insertion loss of rectangular, T-shaped and cylindrical edged noise barriers with rigid, absorbing and soft surfaces. The most efficient design is a T-shape with a soft upper surface.
