Results of experiments involving the propagation of acoustically generated waves on turbulent
plane jets are presented. The jets are produced by a perspex reconstruction of an organ pipe flue
and their behaviour is shown to conform to the predictions of similarity and self-preservation;
i.e. the jet velocity V"' x-1/2 and the jet-width is proportional to x, where xis the distance from
the slit. Thus they are fully turbulent and, as a consequence, well behaved and reproducible. The
