What is the difference between echo and reverberation?

Hi Sreedevi!

Echo and reverberation are different.

Echo:

The phenomenon of reflection of sound from a surface is called echo. For example, when you shout from a valley, you hear an echo.

Reverberation:

The phenomenon of overlapping of sound caused by multiple reflections is called reverberation. This causes the overlapping of several reflected waves. The time gap between the reflected waves is so short that these cannot be distinguished. So we hear multiple noisy sounds. For example, when we shout in a small cave, reverberation of sound occurs.

Cheers!!

Reverb is characterized as random, blended repetitions of a sound occurring within thirty milliseconds after the sound is made. This is all the sound that immediately bounces off any nearby surfaces before it gets back to your ears. So first you'll hear the original sound and then all the stuff bouncing off the walls, furniture, trees, people, giraffes and even acoustic tiling. Your brain is specially equipped to notice reverberations before your conscious perception does.

Echo is defined by distinct repetitions of a sound occurring after 30 milliseconds. This is when you can unquestionably hear a distinct... well, echo of a sound coming back to you. When you are at a big canyon or inside a gigantic room and you, of course, say "Hello!" and then a moment later you hear it again, that's echo.

  •  reverberation for example makes the music instrument sound like it is played in closed room/stadium/hall/garage
  •  you hear echo when you go to Grand Canyon or very large room and you yell "hello" and then you hear hello hello hello ello ello llo llo oo oo o o o. :)

thumbs up plz..........
