It should also be added that sound propagation in solids is audible directly. There is a mechanism known as "bone conduction", where sound propagates through the scull bones directly into the inner ear. This mechanism is responsible for the surprise when we hear our own voices recorded: they appear higher than we are accustomed to. This is because the bone conducts the lower tones better than air.
Bone conduction most definitely uses both longitudinal and transverse waves.
This mechanism is employed in hearing aids and some special equipment such as underwater communications. It was recently used with Google Glass.
So sound is most definitely not longitudinal waves only, no matter what some dumbed down teaching standards would want us to believe.
