Ultrasonics: Ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term sonic is applied to ultrasound waves of very high amplitudes.

Hielscher Ultrasonics specializes in the design and manufacturing of high power ultrasonic homogenizers for lab, bench-top and production level.Ultrasonic power is an effective and energy-efficient means to apply high shear and intense stress. to liquids, powder/liquid mixtures and slurries.. This makes it a strong alternative to high shear mixers, high pressure homogenizers and agitated bead ... Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less..
