Fan Noise Survey

BS 4142 Noise surveys are normally required for a new or existing fan system in each of the following 2 situations;

1. Before you install a noisy piece of equipment
2. After a noise complaint has been made.

The point of this noise survey is to establish the level of the potential noise generated from the fan system and formulate an effective mitigation strategy.

If you have been asked to carry out a noise survey on a new or existing fan system, then you will need to engage a Noise Consultant. Sound Solution Consultants can carry out a BS4142 Noise survey on a fan system for you and ensure that your building complies to the Local Authorities requirements, we would, once engaged on the project, contact the L.A and establish the required criteria and duration of the survey.

One of the first activities we will probably carry out is to contact the manufacturer of the fan system to find out what noise data they have for the equipment. To carry out the necessary calculations, we would obviously need a set of drawings covering the site.

The duration of the noise survey itself, would depend on the intended duration of operation and the type of fan in use. Day to day and background noise levels can change dramatically so the survey is designed to establish the worst case scenario and establish whether this new noise source, would affect any local residents. We will normally man any measurement equipment for the duration of the survey if the units operating hours are Monday to Friday 8am till 5pm. If the operational times of the fan are outside these hours the testing kit will probably be left over night or over a weekend, however if there are no secure buildings on the site then we would probably need to arrange personnel to supervise the kit and to avoid theft or tampering. The survey must be carried out during mild weather conditions, excessive wind or precipitation will affect the results of the survey, therefore we try and avoid these conditions when arranging the survey.

Some units can also emit Low Frequency vibrations when mounted onto buildings which often happens in the case of building fan systems, during our survey, we would also look at this to see if there is any risk, if required, we would offer mitigation advice to avoid the risk of vibrations affecting local residents.

Once the survey has been completed, a full report will be submitted to you to pass onto the local authority. If any mitigation measures are required then we would normally consult with you prior, to completing the report, so that you can review the options open to you.
