An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as the original sound.But sounds are not always reflected.
Where does echo come from?

Why do some sounds not produce an echo?
For a sound to bounce back and make an echo, there has to be a lot of space between the sound source and the thing (wall or mountain) that it hits and bounces back.If there’s no big space, it won’t sound like an echo because the sound that comes back will get mixed up with the original sound.

Why do we hear echo in empty room?
Answer: Echo is heard when the sound gets reflected back. In an empty room, the sound is reflected by the walls so the echo is heard.They absorb sound instead of reflecting them and thus reduces the possibility of echo in the room.

Cover walls with thick blankets, moving pads, tapestries, or quilts. Virtually any soft material will work, though thicker ones absorb more sound than thinner materials. If you don’t mind adding an industrial look to the room, fasten sound-absorbing panels to the walls and, if necessary, the ceiling.
What surfaces produce the best echoes?
Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes. Soft, rough surfaces are good at absorbing sound. This is why rooms with carpets and curtains do not usually produce lots of echoes.

How is sound produced?
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
How is vibration produced?
When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This chain reaction movement, called sound waves, keeps going until the molecules run out of energy.
Do animals voices echo?
Nature’s own sonar system, echolocation occurs when an animal emits a sound wave that bounces off an object, returning an echo that provides information about the object’s distance and size. Over a thousand species echolocate, including most bats, all toothed whales, and small mammals.
