(under the class definition) Process in which the separation is effected or enhanced by the energy of compressional
vibratory waves in a fluid medium, the waves being below, within, or above the audible spectrum.
(1) Note. Pressure pulses in a fluid generated merely by intermittent discharge of a gas are not considered to be compressional vibratory waves under this definition. However, compressional vibratory waves under this definition may be produced by intermittent discharge of a gas, as in a siren.
