Define specific acoustic impedance.
Two media have specific acoustic impedances of 
and 
. The magnitudes of the acoustic impedances may be almost equal or very different. State how these differences affect the intensity reflection coefficient at the boundary between the two media.
or 
), the intensity reflection coefficient at the boundary between the two media would be nearly equal to 1.
), the intensity reflection coefficient at the boundary between the two media would be nearly equal to zero.
