Abstract Study of the principles of the design of fans and of the pipes in the vicinity of the fans providing low noise emission and good performance. A number of parameters that determine the noise emission from fans were investigated by measurements in a test setup. Among the parameters to be investigated were type of fan, dimensions, geometric properties, absorption properties of the surfaces, materials etc. Comprehensive data sheets were prepared on the basis of the test results to document the design and acoustic and aerodynamic performances of the noise protection elements.
