Publisher's Synopsis
When we talk about ultrasound, it is actually a kind of sound energy that a normal human ear cannot hear. Ultrasonic waves are sound waves transmitted above the human-detectable frequency range, usually above 20,000 Hz. The term sonic is applied to ultrasound waves of very high amplitudes. Hypersound, sometimes called praetersound or microsound, is sound waves of frequencies greater than 1013 hertz. At such high frequencies it is very difficult for a sound wave to propagate efficiently; indeed, above a frequency of about 1.25 × 1013 hertz it is impossible for longitudinal waves to propagate at all, even in a liquid or a solid, because the molecules of the material in which the waves are traveling cannot pass the vibration along rapidly enough. Animals have the natural ability to use it when emitted as a wave in communal and navigational perspective. However, humans use ultrasound as well but not without technical assistance and it is used in many industrial and medical purposes. One of the many applications of ultrasonic sound waves is ultrasonic cleaning. It is used to get rid of impurity from certain devices that are absorbed in aqueous solution. Materials like glass, metals, and ceramics can be cleaned using this and in addition to that, ultrasonic waves can be used to remove grease, oil and dirt. Ultrasonic sound waves are also used in industries in order to get rid of chips and oil from machinery and other industrial equipments. It is also used to get rid of sludge and lubricant from the apparatus of aircrafts and automobiles. In addition to the above mentioned uses of ultrasonic waves, there are several other used of it as well. For example, ultrasonic motion detectors use same ultrasonic waves in measuring distance. These motion detectors get the job done by emitting ultrasonic pulses and then measure the time upon the return of those waves. Sonogrpahy is a process that is used to create the images of the internal organs of the body. Fundamentals and Applications of Ultrasonic Waves is intended to provide current exposition of ultrasonics and some of its main applications. Its purpose is to explain and describe the peculiarities of high frequency sound with general acoustics as a foundation. This book presents a number of contemporary applications of ultrasonic waves, developed by the main researchers in their scientific fields from all around the world. Phased array modelling, ultrasonic thrusters, positioning systems, tomography, projection, gas hydrate bearing sediments and Doppler Velocimetry are some of the topics discussed, which, together with materials characterization, mining, corrosion, and gas removal by ultrasonic techniques, form an exciting set of updated knowledge.
