Normal Sound Waves capable of human detection are from about 16 to 20,000 vibrations per second and the speed depends on the elasticity, density and temperature of the medium through which it travels.

The science of sound waves with frequencies above the auditory range is known as ULTRASONICS. They are used in short range ship-to-ship, ship-and-airplane, and in television communications.

Cleansing by ultrasonic waves has many industrial applications and can be used for washing clothes at home in a special ultrasonic washing machine, an outgrowth of the original research conducted by the french scientist, P. Langevin.

Department of Energy research has found ultrasonically cleaned fabrics show acceptable soil removal and sufficient potential to warrant further development.

Compared to conventional methods, ultrasonic washing is faster, uses less energy, requires only small volumes of liquid, cleans more thoroughly, and may be more gentle.
