✦ Synopsis

Sound transmission in 180 ~ rectangular bends in rectangular section ducts is studied. Two models, a potential flow approach and an acoustic modal solution, are used and the relative accuracy of the results is assessed, by comparison with experimental data. An accurate method of predicting the bend's behaviour is described.
