Waves can and do meet boundaries in their medium. When a wave meets a boundary, it can be reflected or transmitted. Reflection can be partial or complete. Reflection can also involve a phase flip
Actually it is refraction process and specifically indentified as total internal reflection. The condition for total reflection is that the ray has to traverse from denser medium to the rarer medium and the angle of incidence has to be more than the critical angle.
Two things: (i) it will be reflected irregularly, and will tend to disperse over a wider angle. This will create a "muffled" reflection - a sharp "pop" will become duller. (ii) there will be partial absorbtion on the surface, and partial cancellation of reflections, so the echo will be softer than from a hard, even surface.
A reflection
A reflection of the front body is known as per-formative self reflection.
In a condition of partial ruin or disrepair

Refraction and partial internal reflection occurs
The suffix for slight or partial paralysis is "-paresis". It is used to indicate a condition where there is a partial loss of movement or weakness in a specific part of the body.

It is a rare condition caused by an incomplete lesion of the spinal cord
$200 to $300 depending on condition.
it is a reflection because the sound waves does not travel to another medium that is the condition of refraction
