An echo is weaker than the original sound because it is produced by a sound wave which travels through the air and then hits another surface.
How does the sound of the echo differ from the original sound?
Echoes. 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.

Is echo same as reverb?
Here’s a quick explanation: An echo is a single reflection of a soundwave off a distance surface. Reverberation is the reflection of sound waves created by the superposition of such echoes. ... A reverberation can occur when a sound wave is reflected off a nearby surface.
Why echo is heard in an empty gym?
Sound will echo in an empty room because if there is nothing to stop the sound reflecting between hard surfaces, such as the walls, windows, ceiling, and floor . Since each surface is not a perfect reflector, some of the sound energy will be absorbed by the surface.

Why can an echo not be heard if you stand 10 m away from a wall and shout facing it?
Why can an echo not be heard if you stand 10 m away from a wall and shout facing it? We cannot hear the echo because the time difference between the original sound and reflected sound will be less than 1/10 th of a second . So, we are not able to distinguish between the two sounds.
How long does it take an echo to return?
If the wall is relatively flat, perpendicular to the source of the sound, and far enough away (but not too far), then you can hear the reflected waveform or echo. If the sound comes back in about 0.1 second or longer , you can readily distinguish the echo.
