With more awareness of noise issues and many developments occurring in already built-up areas it is essential to provide an accurate specification of the noise emitted by building services equipment.
Acoustic testing is important to manufacturers as it enables them to provide useful data about the noise emitted by their product. Acoustic data enables specifiers to make an informed decision when selecting a product for installation.
The aim of this publication is to explain what is being measured to obtain acoustic data and why acoustic data is important and useful.
Some examples of product data sheets are used to demonstrate both good and bad practice when stating acoustic data for a product. References are made to current standards and legislation.
