," Applied Acoustics 46, 1995.
Effects of vortex in acoustics have also been studied by Oosterhuis et al.,  who predicted the relationship between pressure drop and acoustic power
For operating in air, transducers for distance measurement were found to provide good acoustic power
, consistent resonant frequency, and are available at a low-price.
The safety valve noise can be predicted by Lighthill's theory of calculating the acoustic power
of steam discharge.
If the acoustic power
is more than the predetermined threshold, then the input is detected as an event.
The method can be applied to obtain an approximation of the contribution from rigid boundaries of the solid body to the total acoustic power
. Some applications of the method in basic models such as in a single model of side mirror  were carried out, but no application for the prediction of exterior wind noise in full scale production vehicle has been reported.
The acoustic power
radiated by plates in bending vibration is estimated using Statistical Energy Analysis by Rumerman .
is the total energy radiated by the ultrasonic source per unit of time; it can be calculated from acoustic intensity and the area of the radiating surface .
The intense cavitation was induced close to the probe tip for high acoustic power
and might absorb a great part of the acoustic wave energy, resulting in preventing the sound from penetrating deeply in the liquid.
Since the aim is to maximize the acoustic power
, x is chosen so that <[P.sub.inc]> = a*a and <[P.sub.refl]> = b*b.
It was rare that range of frequency and acoustic power
produced by the larynx were not immediately related to range of frequency and power received by the auditory system.
