When designing ventilation systems, one is often unable to obtain very specific details either of the fan to be used or of its noise as measured by the fan manufacturer under controlled conditions. A number of empirical prediction formulae have been developed in the past and are frequently used by system designers and consultants in the early stages of design. A number of these calculation methods are presented and discussed in this paper.
