Variations in the changes of the mean values of
compression wave velocities for gneisses diverge in a wide range ([V.sub.PR] = 1.95-5.24 km/s).

compression wave into liquid lead: (a) pressure; (b) velocity.
However, both speed values were much smaller than the estimated
compression wave speed of approximately 1500 m/s.
This relationship suggested that under the same backpressure, a higher in-cylinder pressure at EVO created a stronger
compression wave during the blow down phase.
When the
compression waves reach the metal plate, the velocity of detonation products changes from [u.sub.i] to [u.sub.m] which is equal to V.
Finally, using the data obtained, we can estimate the average velocity [V.sub.av] of the
compression wave propagating through the felt material.
Note that the strain level, at which the elastic modulus based on the
compression wave velocity is determined, is generally less than [10.sup.-4] ~ [10.sup.-3]% [21].
Simply put, what we hear is a
compression wave traveling through the air.
Using his hands to run along the strings, Close creates a longitudinal
compression wave, which is a similar sound to the vibration patterns that are produced when a finger is run around the edge of a glass, resulting in deep cello-like tones.

The site response models were constructed using different borehole profiles, shear and
compression wave velocity profiles, and the available geotechnical data of CPT and SPT.
Although information can be extracted from
compression wave (P-wave) data alone, the inclusion of shear waves (S-waves) can be used as an additional source of observations to further constrain and narrow uncertainty in the results.
