Compression, which is the "squeezing" together of molecules, and rarefaction, which is the expansion of the "squeezed" molecules back toward their original position, is the oscillatory behavior that causes sound waves. Individually, they are not types of sound waves, because for any wave you need both a disrupting force and a restoring force oscillating between each other.
Sound Waves
Transverse waves have crests and troughs. Longitudinal waves have compressions and rarefactions.
They are longitudinal waves. Because they form compressions & rarefactions when they move.
The vibrations of an audio speaker produce sound waves by compressions and rarefactions in air particles.
Sound disturbance is propagated by compressions and rarefactions through the air medium. Air is a material medium. If such a material medium is absent then sound waves cannot be propagated. These compressions and rarefactions confirm that the wave is of longitudinal in nature.

The vibrations caused by sound waves onto your eardrums are pressure compressions and rarefactions.

No. Those phenomena are characteristic of longitudinal waves, such as for example sound waves.
Sound waves do not propagate in a vacuum, since they are basically vibrations (compressions and rarefactions) in a medium, and in a vacuum there is no matter to vibrate.

That sounds very much like the definition of sound waves - or more precisely pressure waves, which is what sound waves are.
Rarefactions decompressions travel in the same direction, because sound are longitudinal waves.
They are the characteristics of waves ( both longitudinal and transverse waves).
