This paper reports on the performance and costs of a m long experimental noise barrier erected alongside an elevated section of the M4 motorway to protect existing two-storey housing which is as close as 20 m to the motorway.
Measured reductions in L 10 values, at the façades of these dwellings, were around 8 dB(A) at first floor windows and around 4 dB(A) at ground floor :// Combined acoustical and visual performance of noise barriers in mitigating the environmental impact of motorways Like JIANG & Jian KANG* School of Architecture, University of Sheffield, Sheffield S10 2TN, United Kingdom * Corresponding author Abstract This study investigated the overall performance of noise barriers in Read the latest articles of Applied Acoustics atElsevier’s leading platform of peer-reviewed scholarly literature Theoretical and experimental investigations into the acoustic performance of noise barriers in a refracting atmosphere are presented.
The theory is based on the conformal transformation. It can be shown that the sound field in a refracting atmosphere with an exponential sound profile above a flat impedance ground is identical to the sound field in the homogeneous medium above a cylindrically R ESEARCH LABORATORY Department of the Environment TRRL LABORATORY REPORT These results obtained on the eastern side differ from the observations of barrier performance made behind a barrier erected alongside the M4 motorway at Heston 4.

We do not have preferred barrier suppliers and do not recommend any particular barrier products. The following list is provided as a guide to the range of barrier types that are available.
The acoustics ratings are explained here, and items with an asterisk are estimates :// /technical-disciplines/noise-and-vibration/barriers/suppliers. Noise can interfere with sleep, rest and conversation and cause fatigue, irritability, headaches and stress. Surveys show that noise is an important environmental concern for most Australians.

To adequately define the noise problem and set a good basis for the control strategy, the following factors should be considered: type of noise noise levels and temporal pattern frequency distribution noise sources (location, power, directivity) Performance testing is planned before and after installation.
