The phrase "amplitude of the acoustic" is not entirely correct in English as it lacks clarity and specificity.
It can be used in contexts discussing sound waves or audio signals, but it would be clearer if rephrased to specify what aspect of "acoustic" is being referred to.
Example: "The amplitude of the acoustic signal was measured to determine its intensity."
Alternatives: "amplitude of the sound" or "magnitude of the acoustic wave".
The numerical simulation is used to calculate the acoustical power generated by the vortical flow at a given amplitude of the acoustic velocity field and Strouhal number.
Variable Q is proportional to the amplitude of the acoustic wave.
Open image in new window Fig. 5 Relationship between the fractures width and the amplitude of the acoustic wave.
It can be seen that the amplitude of the acoustic displacement is maximum around the defect layer.
Two types of separations were observed as a result of varying the amplitude of the acoustic field.
Thus, a priori the main expected effect of the time variability of P sub is a modulation in the amplitude of the acoustic signal [15,16].
This method is developed by combining two models: (i) a frequency-domain model for the computation of sound attenuation due to a silencer in a linear regime and (ii) a wavenumber space model for the prediction of the nonlinear time-evolution of finite amplitudes of the acoustic wave in a uniform duct of the same length as the silencer.
While articulatory tremor is expected to produce only amplitude modulations of the acoustic wave [9,24], the reported results (Figure 9) indicate that frequency modulation also happens, though with a more limited extent.
These wave fields are small amplitude perturbations of the acoustic wave equation in a linear shear flow; it is shown (in the Appendix) that the perturbations of vorticity and dilatation are coupled, and thus combine features of "acoustic" and "hydrodynamic" modes.
The peak-to-peak amplitude A of the acoustic trace obtained in response to each laser pulse was measured and presented as a histogram for 400 sequential laser pulses.
The amplitude of the fluid acoustic and electric field will decrease with the permeability increasing.
