The CBR development is located in an urban area near main roads, in accordance with British Standards guidance, the LSE’s acoustic consultant has used a maximum target limit of 75dB at the façade of the neighbouring buildings.
All the neighbouring buildings have been surveyed to gauge the potential noise impact of CBR. If the technical assessment identified a potential impact over the target then a possible noise problem could arise.
The type of window will make a great deal of difference to the impact of noise (assuming it is kept shut) This is why we have surveyed all windows in all rooms which might be affected by the CBR works.
We have engaged with our acoustic specialist to try and mimic what this sounds like in real life. The extend of reduction will vary considerable depending on the source of noise and the distance from it. But as an example the following gives a approximate indication.

Please note the files are to show the difference between the single glazing sound source and the two subsequent sources, it is not a representation of the actual noise as this would need to be calibrated more accurately on each PC.
