Abstract
'SINGING' in wind tunnels has been observed from time to time, and we recently had the opportunity of making a study of the phenomenon in the wind tunnel of the Aeronautical Department at the University of Sydney. This tunnel is of concrete construction, has an enclosed working section, and the aerodynamic design is conventional. The corner vanes are of the constant-width annulus type and are cast in concrete with reinforcing iron rods. The cross-section and spacing are shown in the accompanying figure.
