Air Conditioning is becoming increasingly popular in a variety of types of premises. It is commonly integral in the design of modern offices, retail outlets and leisure facilities. But it is not just the commercial sector which uses this type of temperature control. Despite the fact that air conditioning is arguably unnecessary for most of the year it is becoming increasing popular in residential premises as well.
As air conditioning units appear on the outside of more and more buildings there is increasing concern about their visual impact and the noise which they generate. While many of the new units may be regarded as having a negligible impact on noise levels, the collective effect is that they contribute towards an upward creep of background environmental noise levels.
If a single unit develops a defect it can potentially cause a very significant amount of disturbance and misery to a large number of people.
