One or more elongated members, such as bars or tubes of an elastic material are sonically vibrated, by means of a mechanical oscillator coupled thereto, at a frequency such as to set up resonant elastic standing wave vibration in the elastic resonators. A conduit or chamber is provided in which material to be treated or parts to be polished along with an appropriate fluid treatment material are placed, the parts and material either being flowed through the conduit or retained therein for a predetermined treatment time. Sonic energy is coupled from the resonator member or members to the treatment conduit at selected positions along the standing waves generated in the resonators, this coupling being made adjacent the node and anti-node of such vibration in one embodiment; at two anti-nodes in a second embodiment, and a single anti-node in a third embodiment, to obtain various types of vibratory motion in the treatment conduit or chamber for various effects on the parts or other material being treated.
