Planning and Noise
Applying for planning permission and think you might need an acoustic report? Or perhaps you have received your planning conditions and have items relating to noise that you need to discharge. Whatever your project, the dBx Acoustics team can help you.

A suitable scheme of sound insulation?
This is a common phrase in planning conditions, but what does it mean? It’s not as confusing as it sounds. In setting a condition like this, the Local Planning Authority is generally looking to make sure that occupants of your property are protected from noise including traffic noise, industrial noise and entertainment noise. They may also be looking to ensure that the noise you generate, for example if you’re opening a bar or restaurant, doesn’t adversely impact surrounding premises.
To discharge these conditions, the first step is to carry out a noise survey to quantify the existing environment – before you even put a spade in the ground. This allows us to set a baseline for existing conditions to assess noise against and to make sure that the acoustic recommendations are as proportionate and cost effective as they can be.
Depending on the complexity of your project, we use a variety of methods from calculation to modelling, to examine the potential for noise disturbance. We use standards such as BS 8233 when considering how noise will affect residential and commercial development. This allows us to work with you on an appropriate acoustic specification for your glazing and facades, and to advise you on whether a natural ventilation strategy will be viable.
What the heck is BS 4142?
You’ll see BS 4142 mentioned in a planning condition when your development is likely to have some form of external plant (e.g. extract fans, air conditioning units).
BS 4142 gives us a framework against which to assess the noise impact of both existing and proposed noise sources. Once again, the first step is to carry out a noise survey to quantify the existing sound environment. This lets us set a ‘rating level’ (often the required rating level is detailed in the condition). We can then look at the plant you have selected, its location and hours of operation, and determine whether you’ll be compliant with the condition. If you aren’t compliant, we can work with you on mitigation measures such as acoustic screening and louvres.
I’m still confused…
Don’t worry. That’s why we are here. If you aren’t sure what you need to do, or if you have a planning condition you can’t make head or tail of, just give us a call or drop us an email. We’re always happy to talk it through with you without obligation.
