The shape of the resulting pressure waves
can also be quite complex.
The Shockwave C2 IVL Catheter is a proprietary tool designed to fracture problematic calcium using sonic pressure waves
in order to facilitate stent delivery, deployment and optimal expansion, thereby improving blood flow to the heart muscle.
Worse still, the blades are proven to kill bats, not by impact but simply by pressure waves
in the air turbulence caused by these blades.
The lens relies on ultrasonic pressure waves
to navigate organs.
However, according to Philippe Lognonne, a planetary seismologist at Paris Diderot University who is in charge of the NASA instrument, the noise is most probably caused by low-frequency pressure waves
from atmospheric winds on the surface of the planet.
Shockwaves are defined as pressure waves
(or transient pressure oscillations) that propagate in three dimensions and typically induce a clear increase in pressure within few nanoseconds.
The pressure waves
in the axoplasm accompanying the propagation of an action potential were recorded by Terakawa .
Pulse pressure amplification (PPA) is conventionally understood in clinical practice as the increase of pulse pressure (PP) amplitude as pressure waves
propagate distally in the systemic network.
"The stuff you hear is pressure waves
; the stuff you feel vibrating your seat is particle motion."
Therefore, the mechanism producing strong pressure waves
and knock was investigated in this study by using a supercharged, optically accessible test engine to generate a wide range of knock intensities from weak to strong knock.
Investigations of the characteristics of pressure waves
, which are generated, for example, by an electric discharge in a liquid, involve recording the total profile of the pressure wave
at a given point in the volume of the liquid.
The Shockwave Medical Coronary Lithoplasty System is a therapy designed to treat calcified coronary artery blockages with lithotripsy, sonic pressure waves
historically used to treat patients with kidney stones.
