摘要：
The results of an experimental investigation of acoustic perturbations in the working section of a wind tunnel with circular wall perforations are given, together with the properties of the gas flow near the wall at the edges of these perforations. This flow takes the form of discrete inhomogeneities having dimensions considerably greater than the boundary layer thickness on an impermeable plate with similar free-stream parameters.
