Acoustic Propagation. Recall: Sound waves are compression waves. Sound requires a compressible medium Question: Can sound propagate in a completely incompressible medium? Can sound propagate in a vacuum?

Acoustic Propagation Recall: • Sound waves are compression waves. • Sound requires a compressible medium Question: • Can sound propagate in a completely incompressible medium? • Can sound propagate in a vacuum? • Acoustic propagation speed depends on media compressibility– the more incompressible (denser) the medium, the faster the propagation speed
