NOISE BARRIER FOR BRADBOURNE RESIDENTS

This article gives a brief account of the way in which traffic noise from a new interchange on the Nottingham Inner Road was screened from the residents of a housing estate, particularly these in Bradbourne Avenue. The author first outlines the problem and gives details of noise measurements that were made in April 1973, which indicated that protection could be provided by the erection of noise barriers on the edges of the north - and south -bound carriageways. Details are given of the barriers used, that on the northbound carriageway being 1 m high by 207m long, and that on the southbound carriageway being 2m high by 275M long. They consisted of bitumen coated steel panels on galvanized steel posts and rails. A figure shows constructional details of the barriers which were of three types (two different heights and mounted on an existing aluminium crash barrier). A table gives noise level measurements obtained before and after erection of the barriers, which show noise reductions of between 3 to 8dba in spite of increased traffic density and speed. The total cost of the barriers is given as found13,500 and it is reported that the noise levels for 15 houses was reduced to below 68dba (the level at which the highway authority may have A duty to install sound insulation). /TRRL/
