You want to look up "acoustic impedance" and read all about it. Proper matching of your different materials' acoustic impedances, in a particular order, can enhance or inhibit the transfer of energy between layers. For example, the gel that the technicians use when you have an ultrasound test (ultrasound is simply a high frequency vibration) is there to help match the acoustic impedance of the probe to that of your skin - if you've ever seen when the gel dries up, the images become very poor until more gel is added.
