Magnitude of vibration vis-a-vis charge per delay and total charge... Vibration and noise having a geometric attenuation with respect to distance,sometimes poses problem in estimating its magnitude from the predicted best-fit propagation equation derived from wide range of ...
Frequency content of simulated echoes at different steps of generation.... (D) Spectrum of the final echoes including pulse emission characteristics, HRTF and distance and frequency dependent atmospheric as well as geometric attenuation.
The practical formula of ground vibration attenuation induced by the parallel vehicles on a ring road... In this paper, based on the transient moving load equivalent radius, multiple non-point source within as multiple small non-point source, ground vibration amplitude for multiple small non-point attenuation stack, on the basis of considering the ground more than car parallel, will vehicle load simplified as parallel concentrated load, according to the harmonic waves equivalent radius, considering different soil types of geometric attenuation coefficient, gives a practical formulas with ring road of ground vibration attenuation caused by parallel vehicles....
