A numerical investigation of the sound resultant from a compressible flow about an 18% thick circular-arc aerofoil, for free-stream Mach numbers between M = 0.7 and M = 0.82, and a Reynolds number Re ~ 10^7, is presented in this paper. Within this range of parameters, self-sustained shock oscillations may be present on the upper and lower aerofoil surfaces. The transient flow-field was computed by detached-eddy simulation, with the solution used to quantify acoustic sources, defined by Howe's analogy, that are propagated using a wave expansion method. The results were compared with available experimental and numerical results from other studies of the same configuration.
