Noise measurements were completed of existing ambient noise levels at the housing adjacent to the factory site. Measurements were also completed of existing factory plant; these were used as the basis for assessing noise impact from the new extension.
The assessment was completed using the method set out in BS 4142:2014 and to recommended internal noise limits set out in BS8233:2014 and WHO.
The assessment model not only included noise break out from the building extension, but also the influence of an enclosed conveyor system that will link the existing factory production line with the extension. By creating a noise model, it was easy to identify potential noise problems for existing dwellings.
The results of this work determined that noise from the proposed development should have a minimal impact on existing housing.
