Since sound reflects off of soft surfaces better, it can reflect off of metal, walls, wood, paper, and a bunch of more soft surfaces.

Why is the sound reflected in mountain area?
This is because sound travels in waves and rebounds off the hard mountains to reach your ears again. There are limited soft objects that absorb the sound, and therefore an echo occurs. This is the reason why you usually only hear a single echo.
How is a ball dropping to the floor and bouncing back up like an echo?
Sound waves, like physical objects, can "bounce" (if they are not absorbed by soft surfaces). The same way a ball hits the floor and uses the energy of impact to rebound, sound waves can hit the walls of a cave or empty room and return in roughly the same direction they came from.
Why do balls bounce better on hard surfaces than soft ones?
Soft surfaces absorb quite a lot of the energy (by deforming) that the ball uses to spring back up, whereas hard surfaces don't absorb that energy (because they don't deform), and so the energy is used to deform the ball, which is then converted back into kinetic energy and the ball bounces.
Why are echos produced in empty areas?
Because there is nothing to 'absorb' the sound, echo's are basically a sound reflected by it hitting a surface, if you walked into a house with nothing in it, just the walls, floorboards or concrete floor and ceilings then the sound echos because there are no soft things or cushiony things to absorb the sound and stop it reflecting.
Can soft and rough surfaces absorb sound?
The natural property of the material has that ability. Alot of objects absorb wound, for example the sides of your stereo are sound insulators. However, not all have the same or even this ability at all. As for soft and rough, they most likely won't play a factor, therefore you should look into the material of objects to possibly determine the insulation of sound.
How echo is formed?
An echo is formed by sound waves bouncing back off of solid surfaces. The greatest effect happens in small empty rooms with few or no soft furnishings. Soft furnishings absorb sound waves and so would counteract the effect.
Why are soles of shoes grooved?
To provide better traction on soft surfaces.
Why do some bikes have broad wheels?
To get better traction on soft surfaces.

Why the soles of our shoes are grooved?
To provide better traction on soft surfaces.
Why use soft tiles for the ceiling of a recording studio?
Soft surfaces may dampen the reflection of sound waves, but soft tiles are not the only way to improve the sound performance of a surface. The shape of the surface, thickness of the material, and material type are all important.

What is room flutter?
Room flutter is basically echo. Parallel surfaces of the room cause sound to bounce back and forth quickly causing the echo to quickly echo creating a flutter or slap back sound. This is usually NOT a desireable trait for a room especially if you're using the room for any kind of audio work (recording, mixing, rehearsing etc). I say usually because there are instances where you DO want a room to flutter, as when implementing an echo chamber. Remedies for this phenomina can be as simple as adding a carpet or soft furnature to full blown acoustic treatments (see auralex.com for more info on that)
What bird has a quack that doesn't echo loud enough to hear?
Duck quacks do echo.It is a scientific myth that a duck's quack does not echo. Research has shown that a duck's quack does echo, but it is hard to hear because it is difficult to distinguish the quack from the echo.There are several reasons why it is difficult to hear the echo:Echoes are produced after loud noises. Ducks quack very softly, so the reflected sound is difficult to hear.A reflecting surface is needed to hear an echo. Ducks tend not to live near reflecting surfaces such as cliff faces or buildings. An echo could be heard more readily if the duck quacked whilst flying past such as surface.
Does the Cozip Soft Polycarbonate Slim Cell Phone Case have a soft rubber type back to help it grip surfaces better?
No, but the polycarbonite shell itself is slip resistant.
Is maracas a loud sound or soft sound instrument?
SOFT
What is made from felt and why?
sound deadening, insulation, furniture feet felt is soft and filled with air so it doesn't scratch surfaces and limits heat/cold transfer and reduces sound transmission
