Chiller Noise Survey

BS 4142 Noise surveys are normally required for chiller units 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 the survey is to establish the actual level of the potential noise genrated by the source, in this case a chiller unit and to formulate an effective mitigation strategy.

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

We may then contact the manufacturer of the chiller unit to find out what noise data they have for the equipment and what impacts this may have on the local area. To carry out the necessary calculations, we will need a set of drawings covering the site and the chiller system in question.

The duration of the noise survey itself will depend greatly on the type of noise source we are surveying and its intended duration of operation. Due to the great variation in background noise levels as well as day to day noise changes, the survey is designed to establish the worst case scenario and establish whether this new noise source, would affect any local residents. In most cases the measurement equipment would normally be manned for the duration of the survey. If the units operating hours are outside Monday to Friday 8am till 5pm the kit would probably be left over night or over a weekend. In some cases 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 as excessive wind or precipitation will affect the results of the survey, in most cases we will try and avoid these conditions when arranging the survey.

Many units can also emit vibrations when mounted onto buildings, during our survey, we would also look at this to see if there is any risk of your chiller unit causing vibration noise. 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.
