Noise Barrier Effectiveness at Jerry Erick blog

Noise Barrier Effectiveness. Every additional meter above the line of sight reduces the sound by an additional 1.5 decibels. They do not completely block all. The following sketches show the general principles. Noise barriers are solid obstructions built between the highway and the homes along a highway. Determining the effectiveness of noise barriers has attracted the attention of researchers for the past 40 years, and a wide variety of both mathematical and experimental approaches have been developed. The effectiveness of a noise barrier is governed by the path length difference (the amount by which the top of barrier cuts the line of sight. A noise barrier’s effectiveness is determined by the degree to which it forces sound to bend to reach the receiver. Mathematical methods have been widely used to determine the diffraction properties of the barriers. According to metrics by the department of transportation, in order to achieve a 5 decibel reduction of noise, a barrier must be built at the line of sight (and hearing) of the average individual. This paper presents findings from a longitudinal study evaluating the efficacy of noise barriers in three residential areas alongside.
