EN Noise of machinery and mechanical assemblies can be synthesised by computer using a particular jigsaw-puzzle sub-structuring approach. This approach is aimed at low noise design of industrial products where noise is generated by individual sources built in a noise-free housing. All the major noise mechanisms are dealt with in a step-by-step procedure, which can be potentially used even by less advanced industries. The novelty of this approach is that it predicts trends in the overall noise by combining data from real noise sources with a simplified modelling of the main frame (housing). The connectivity between the source(s) and the frame is ensured by well known impedance coupling rules. The simplified frame model has the advantage of being robust and easy to implement. The critical components are the noise sources which have to be characterised by measurements. The characterization techniques can be quite demanding, but reveal a lot of useful information to the designer apart from providing the input data to the synthesis algorithm. The paper outlines the basics of the approach and shows some examples of its use.
