If noise is defined as unwanted sound, then it’s a survey that measures and assesses unwanted sound. But that doesn’t answer your question does it. Close you might say…. but no cigar.
Ok try this.
A noise survey is always specific to the question it is required to answer, and there is usually some government guidance, legislation or British Standard that is also specific to that same question.
For example, a noise survey to answer a planning condition imposed by a local authority would draw on guidance from WHO Guidelines for Community Noise and BS8233 where the developer wishes to put residential dwellings near an existing noise source, or BS 4142 where a new noise source such as an air conditioning unit is to be introduced close to existing residential.
Then we have Reverberation Time noise surveys which measure the time it takes for noise to decay inside of a building and are used to control internal acoustics to aid speech intelligibility amongst other things. And of course Sound Insulation noise surveys which measure the amount of ‘acoustic protection’ you may get from a party wall or floor surface, governed by British standards prescribing both measurement and calculation methods and by current building regulations in the form of Approved Document E 2003.
And noise at work surveys covered by the Control of Noise at Work Regs obviously designed to help protect the hearing of workers in noisy environments, construction noise surveys under section 61 control of pollution act 1974, noise surveys for minerals extraction from quarries under Minerals Policy Statement 2….. There is guidance that covers noise in schools, hospitals, prisons, student accommodation, wind farms, dog kennels and offices to name but a few……..
Noise Surveys. They come in all shapes and sizes. If you need a noise survey but aren’t sure where to start. Just ask. We’re happy to offer advice.
