Speed up
Only if it exceeds the speed of sound while still in Earth's atmosphere. After that, there's no shockwave, just as none is produced by the GPS satellites, TV satellites, and the Moon, all of which move at several times the speed of sound.
Think of a solid and there's your answer. Wood, metals, glass... Imagine putting your head on a solid, ear down, which materials would best transport the sound to you if someone tapped the same solid but a metre away? Those are the the solids that best transmit sound.
Sound travels fastest through a nonporous solid medium, such as steel.

Light is an example of an electromagnetic (EM) wave. EM waves are transverse waves, not compressional waves. Sound waves are compressional waves, so both sound traveling through air and water would be compressional. Waves traveling along a coiled spring compress the coils together and spread them apart, so this is also an example of a compressional wave.

The speed of sound is only 768mph.
The kidneys would secrete elevated amounts of erythropoietin.

I would expect any movement of matter to cause some sound.

Actually, sound travels slower under water than underground. Sound is a vibration in molecules that we perceive as noise. Water's molecules are rather loose compared to a solid's molecules, so it would travel slower underwater compared to traveling underground.
