For safety purpose, the protective structures are better to be constructed in a site with small acoustic impedance and a large attenuation factor.
Another variant of the general EWSD criterion is determined by considering one more time that the direct path undergoes a large attenuation.
It is not a surprise that to get a fast rolloff, 12 dB per octave or faster, and a large attenuation in the stop-band could require a filter of more complexity.
A typical scenario which justifies the introduction of the (EWSDMP) consists in considering a direct path signal undergoing a large attenuation, while other reflection components arrive at the receiver without suffering any degradation.
There was a large attenuation of oxygen consumption (VO2) relative to BWS (p < 0.001), while there were trivial-moderate reductions in respiratory exchange ratio, minute ventilation, and respiratory frequency (p > 0.05), and small-large effects on HR and RPE (p < 0.01).
Since the spectral envelope of the OSACF of noisy observations, in comparison to the conventional two-sided conventional ACF, strongly enhances the highest power frequency bands corresponding to the spectral peaks, a large attenuation of the noise components lying outside the enhanced frequency bands would occur. .
As the frequency is increased (to Ω = 50, for example), the system response is dominated by waves of increasing type order (s= 15, 16,...,) and a column of gas bubbles has the effect of bringing a large attenuation to the shell response.
Alternatively, gene regulation data also show that, during the dormant phase, there is a large attenuation of the Mtb F0-F1-ATP synthase pump, indicating impaired ATP production during the nonreplicative state of mycobacteria [ 4].
We also functionally verified the involvement of CaMKII by our pharmacological inhibition experiments in which we showed that CaMKII-inhibition resulted in a large attenuation of acutely enhanced Ca release from the SR (decreased Ca transients and reduced SR Ca leakage).
