How does an echo occur?
Sound can bounce off hard surfaces, like light can off bright surfaces. A sound starts and the sound bounces, the sound then bounces off another wall and another and so on. When it bounces it splits into all the directions its side of the wall (if you imagine a protractor against the wall the sound will travel in all angles on that side of the wall. Every time it bounces the sound gets quieter as the energy is lost. The more hard surfaces in a room the less energy is absorbed by the surface. Therefore the reason this does not work in your house it because you may have carpets, pillows on chairs and sofa's.
What happens when light or sound is bounced off an object?
Light reflects and sound just bounces off.
What is it called when a sound wave bounces off a surface?
Reflection
How do floors absorb sound?
the sound travels when it reaches carpet it absorbs it but on tile it bounces off
How does sound produce an echo?
to produce an echo, the sound wave bounces off a surface and then comes back
What do you hear when sound bounces off a smooth surface and is heard more then once?
An echo.
Why do people often hear echoes in the mountains?
cause the sound bounces off other mountains and you hear the echoes.

How could soundwaves be focused by using reflection?
Not all sound that hits matter is absorbed. Some of it is reflected. That means sound bounces off the solid matter the way a tennis ball bounces off a wall. Sound reflected back to its source is an echo.
How do you produce an echo?
Imagine a pool of water. If you dropped a rock in the water you would cause ripples that would travel out evenly in all directions. When one of those ripples hits a wall, you can see that the ripple bounces off the wall. Sound works the same way. Sound is basically just ripples in the air (vibrations). When a sound vibration hits a wall it bounces back much like the ripples in water. * When you hit something and waves travel through the air to your ears. Sometimes sound reflects again.

Is when a sound wave bounces off an object and returns in the direction from which it came?
that isnt a question...? Perhaps the question was to be something like: "What is happening when a sound wave bounces off an object and returns in the direction from which it came?" Answer: The sound is echoing.
