Microcomputer aided system for the analysis of sounds from an annular cascade has been developed. The system not only performs primary data reduction and graphic display, but possesses potentiality for future active use as a controller of otherwise disconnected measuring instruments. An attempt was made to apply this system to study the feature of the sound field inside an annular duct, with its reference to the acoustic resonance induced by vortex shedding from the trailing edges of the installed cascade blades.
