Ultrasound

Ultrasounds are sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and to accelerate chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. Scientist are also studying ultrasound using graphene diaphragms as a method of communication.

Ultrasound (band)

Ultrasound are an English indie band, predominantly active during the late 1990s. Although the band's focal point (in particular for reviewers) was their tall, obese singer/guitarist Andrew "Tiny" Wood, the main songwriter was guitarist Richard Green, with the line-up completed by drummer Andy Peace, keyboardist Matt Jones and bass player/second singer Vanessa Best.

Having split up acrimoniously in 1999, the band reunited in early 2010 with their first concert in eleven years scheduled for a benefit event in September of that year.
