The meaning of SUPERSONIC VELOCITY is a fluid velocity relative to a body in the fluid that is greater than the local velocity of sound in the fluid.
Volume velocity definition: the movement caused by a sound wave of a unit volume of a sound-transmitting medium through a unit area per unit of time.. See examples of VOLUME VELOCITY used in a sentence.
The meaning of VELOCITY MICROPHONE is a microphone (as the ribbon microphone) whose very light and flexible diaphragm follows almost without phase lag the air movements in the sound waves that actuate it.
aThe concentration is derived from accurate measurement of the velocity of sound in the mixture, and of the mixture temperature. It is necessary to input the molecular weight and the principal specific heat ratio for the two components.[translate]...

methods to measure bullet velocity with an accuracy of 1% or better. In one method, a microphone is placed within 0.1 m of the gun muzzle and a bullet is fired at a steel target 45 m away. The bullet’s flight time is the recorded time between the muzzle blast and sound of h[...
of exact physical meaning.Based on the idea of Wyllie's time-average equation,a sea-floor sediment sound velocity forecasting model is established with the relationship of distance,time and velocity.In the model,the introduced parameter coupling coefficient stands for the impact of stacking and ...
We establish that the dispersion curves, 蠅(k), used in analytical theories, in the case of liquid metal has the meaning of a average frequency of a spectrum of collective excitations at the given k value. The application of this method to liquid cesium at various temperatures has shown ...
and excess sound velocity-impacted protective material, where the highest density of protective material is at the cladding outer surface to protect the cladding from reactor environment and any further oxidation of the zirconium, where the integrated middle volume provides structural integrity for the ...
Following the rise of virtual reality is a demand for sound field reproduction techniques that allow the user to interact and move within acoustic reproductions with six-degrees-of-freedom. To this end, a mixed-source model of near-field and far-field virtual sources has been introduced to impr...
