In acoustics and audio, a transient is a short-duration signal that represents a non-harmonic attack phase of a musical sound or spoken word. Acoustics is the interdisciplinary science that deals with the study of Sound, Ultrasound and Infrasound (all mechanical waves in gases liquids and solids It contains a high degree of non-periodic components and a higher magnitude of high frequencies than the harmonic content of that sound. The magnitude of a mathematical object is its size a property by which it can be larger or smaller than other objects of the same kind in technical terms an Ordering Transients do not directly depend on the frequency of the tone they initiate. See also onset (audio). Onset refers to the beginning of a musical Note or other sound in which the amplitude rises from zero to an initial peak
Sonar
Transient is often used by sonar operators to enter large numbers of crit strings, referring to sudden, unnatural changes in the acoustic environment. This is usually caused by an unnaturally fast moving object. It is most often applied for military use, referring to unexpected sounds emanating from another vessel such as operating machinery, a metal hatch being slammed, or the flooding and pressurization of torpedo or vertical launch tubes. A torpedo tube is a device for launching Torpedoes in a horizontal direction A Vertical Launching System ( VLS) is a type of Missile -firing system used aboard the Submarines and surface vessels of several navies around the
