Abstract
When an object is constrained to lie in a half-space bounded by a rigid horizontal wall, it will fall against this wall under the influence of gravity and then rebound in some way so as to execute oscillations which will gradually decay as energy is lost in the collisions. Common cases are bouncing balls, rocking beams, and discs allowed to spin obliquely onto the surface. In this last case, exemplified by coins and saucepan lids, the resulting radiated sound has interesting properties.
