Consider the difference in sound between a large empty room that only has hard walls to reflect sound compared to a room with different kind of furniture and curtains or drapes. An echo occurs when sound (sound waves) reach a solid object that reflects the sound away and back to where it originated. If there is no echo than any or all of the following occurred:
- The sound waves were reflected in a different direction.
- The sound waves were absorbed when they reached a soft material that does not reflect sound well. The sound energy is converted to smaller vibration in the material which dissipate.
- The sound waves were attenuated (lessened) as they traveled through the air until it was inaudible (couldn't be heard). Some of the waves are absorbed by the ground, grass, trees or bounced away by obstructions and the rest are absorbed by air particles which gain a little energy from it.
Interestingly, the amount of air particles over water is less than over land and most people are aware that sound travels further over water.

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.

What natural disaster might a hook echo suggest is likely to occur?
The hook echo is one of the classical hallmarks of tornado-producing supercell thunderstorms as seen on a weather radar. The echo is produced by rain, hail, or even debris being wrapped around the supercell. The National Weather Service considers the presence of a hook echo as sufficient to justify issuing a tornado warning

Did echo be heard on a ho tter day?
An echo can be heard during a hotter day. In fact, soundwaves travel faster during hotter days so a person would hear the echo a lot sooner than they would on a really cold day.

What happens to echo after narcissus runs away from her?

What happens when sound gets louder?
It means that the amplitude of the soundwaves is increased, or is increasing if the sound continues to get louder.
Why is there an echo in the gym of a school?
more than likely due to the solid walls, hardwood flooring and non sound absorbing materials used in the bleachers. The lack of articles and material that would absorb sound waves provides a surface to bounce the soundwaves around creating an echo.
Why is echo only occur in mountainous areas?
Because an echo needs a solid surface for the sound to 'bounce' off.
