BS4142 noise surveys, noise assessments and reports
BS4142 NOISE ASSESSMENT: WHAT WE DO & WHY IT MATTERS TO YOU.
The British Standard BS4142 2014 noise assessment standard is one of the many procedures that we use. We use this and other standards to assess noise and noise complaints. Our main objective is to ensure your planning conditions or current environment adheres to the BS4142 noise assessment standard.
We're a mechanical engineering and acoustics consultancy with extensive vibration, structural dynamics, noise and acoustics experience. Our expertise is in noise reduction and mitigation through vibration control, mainly at the noise source.
WHY DO WE USE THE BS4142 NOISE ASSESSMENT STANDARD?
We use the BS4142 assessment standard to assess adverse impacts, industrial noise sources and commercial noise. We report on our observations and analysis of the noise assessment. We then use our extensive mechanical engineering expertise in mechanical vibration to mitigate the noise at its source.
So you get a BS4142 noise assessment with financially efficient and effective mitigation measures. Recommended by our professional engineering team. All mitigation measures are cost effective and practically implementable.
Our main objective is to quieten machinery and equipment. Reducing environmental noise, and allowing the machinery to blend in with the environment.
The BS4142 noise assessment standard is used for:
The methods for rating and assessing industrial and commercial sound are applicable to:
sound from industrial and commercial premises and from manufacturing processes
sound from stationary systems, like mechanical and electrical plants and equipment;
sound from the loading and unloading of items at industrial at or in industrial and commercial facilities;
sound from mobile machinery that is the core of the total sound emanating from the commercial property, i.e. cranes, forklift trucks, and for harbour equipment and machinery.
BS4142 uses outdoor sound levels and ratings to assess the likely effects of sound on people inside or outside a dwelling.
WHY USE ENVIRONMENTALLY SOUND FOR YOUR BS4142 survey?
Environmentally Sound Limited is a mechanical engineering and acoustics consultancy. When it relates to noise, our objective is to:
improve living and working environments,
improve and design products to operate quietly in those environments
We use our engineering expertise in mechanical vibration to mitigate the noise at its source and improve the design to reach that objective.
Therefore, we use BS4142 noise assessment to ascertain the levels of noise and by what margin it exceeds permitted levels. The level by which it may exceed, is dependent on your local planning authority or council handling your planning application.
Every council has different pass or acceptance criteria when reviewing BS4142 noise assessment reports to grant you planning permission.
Recently, it was confirmed that certain boroughs in Greater London will accept noise levels within 10dB of the background noise. And councils in the countryside want the specific noise to be the same as the background noise.
Once we ascertain the noise level and the penalty, our vibration consultants address the noise source.
How much does a BS4142 noise assessment cost?
You are paying for the BS4142 noise assessment report and the mitigation recommendations. No BS4142 noise assessment is the same as another, as:
the source of the noise is different, and
it may be a different authority requesting the BS4142 noise assessment.
Our consultants provide mitigation measures, so that you don't need an additional contractor to mitigate the noise.
A BS4142 noise assessment with a BS4142 noise assessment report costs as little as £1150+VAT. This is the lowest price that we offer with all the resources required for a proper and professional noise assessment. Prices may vary, depending on the noise assessment required.

The information included in the BS4142 nosie assessment report
Statement of qualifications, competency, professional memberships and experience relevant to the application of this British Standard of all personnel contributing to the assessment.
Assessed and surveyed source
description of the main sound sources and of the specific sound;
operational hours of the day;
mode of operation (e.g. continuous, intermittent, tonal and impulsive, or is it dependent on the weather conditions);
is the source of the sound running at full load, or partial load
layout of the premises in which the main sound source is located
Subjective impression of the person taking the recordings
Does a sensitive receptor exist in the area, i.e. school, care home etc.
Locality of the source to receptors, and the topography of the landscape and buildings.
equipment used for the assessment
Mitigation measures. (Sometimes, a noise management strategy report is requested instead of mitigation measures).
There is much more to adhere in this standard. But it's the responsibility of the person making the measurements and assessment recordings.
BS4142 noise assessment report mitigation measures.
People concerned about specific noise levels request sound level assessments. And if someone is concerned about a noise level, it does suggest that they already know the outcome.
In our experience, mitigation measures were always required after noise assessments. And it was a pleasure to provide the mitigation measures and put them in place.
Providing desirable noise reduction or mitigation measures is usually requested in the BS4142 noise assessment report. And therefore, we add the mitigation measures to the conclusion of the BS 4142 noise assessment report.
We are an engineering company with acoustic engineers and mechanical engineers. We address the source of the noise, as we have an appreciation of how the industrial equipment function. We can mitigate the source of the noise, and how the noise emanates from the machines and equipment or plants.
It is our ability to dig deep, to find the source and mitigate the noise at its source. Which is also the cheapest approach to mitigating noise.
