Sound is just a mechanical vibration of the particles which flows in all directions away from the source.
It can be reflected from objects or be absorbed...it depends on the type of material, and also its surface - probably a soft material with complicated surface, like wool, or cushion will absorb most of the sound, whereas a hard, compact object with a glazed surface, like glass or concrete, will reflect more.
Echolocation is actually a process- it can't hit anything. In echolocation, high frequency sound waves are sent out by an animal. When these sound waves hit an object, they bounce off of it and reflect back to the animal. The animal can gather information about the object from these sound waves such as its size, shape, and distance.
When a sound hits a flat surface it bounces back in exactly the same direction as before, in exactly the same frequency and pitch.
What happens when sound hits a thin membrane is that it vibrates the tympanic membrane. The tympanic membrane is also known as the eardrum.
It bounces back.
When all light that hits an object is absorbed by it the object appears black. Similarly we see a wight object when all light that hits the object gets reflected off it!!!!!
They are either absorbed [softsurface, e.g. wool] or refected [hard surface, e.g. metal]

generally speaking, the sound is absorbed.
It bounces back.
the velocity of the object increases until it hits the ground

the sod makes a higher pitch
Light reflects and sound just bounces off.
It bounes back where it came from
