The generation of aeolian tones by the interaction of a low Reynolds number, low Mach numbers flow with a rigid square cylinder attached with a rigid thin flat plate is numerically investigated. When the length of the plate is varied from L = 0.5D to 6D, where D is the side length of the square cylinder, the results can be grouped into three distinct regimes. For the first flow regime (L lesssim D), the aoelian tone levels decreases with increasing of the plate length. For the second regime (2D lesssim L lesssim 4D), the aeolian tone levels are always higher than the single square cylinder case and they increase with increasing of the plate length. For the third regime (5D lesssim L lesssim 6D), the levels of the aeolian tone decrease as the length of the plate is increases but the levels are higher than other regimes. These acoustic results can be explained in terms of fluid mechanics occurring in the near wake of the cylinder.
