Abstract
A study of the control of pairing sound of two identical thin vortex r ing by means of a thin control vortex ring of opposite circulation is reported. Amplification add attenuation of the pairing sound have been observed. The amplification and attenuation are due to the effect of the control vortex ring on the interaction of the two pairing rings. F our basic types of interaction of the three interacting vortex rings a nd different degrees of amplification and attenuation have also been e stablished.
