There is no where for the sound wave to reflect
Sounds echo when there is nothing else to absorb the sound.
So in an empty room, there would only be the walls to absorb the sound, but walls don't absorb sound. They bounce it back. So, when you are in an empty room or a cave, nothing absorbs the sound and it is bounced back.
However, if you were to put a couch in the room, it would no longer echo, because the couch soaks up the sound.
There are more echoes in an empty room because there is less in the room to absorb the sound waves, so they bounce around in the room longer.
due to the echo. it has different wave lengths fo can not be hear clearly.
no you can't unless if you have super hearing! Because it's hard for the sound to bounce of the walls if there are things in the way like a frame which would slow it down...
I would expect to hear an echo in a gymnasium because if you think of a basketball bouncing just 1 you hear it coming right back at you.

When a sound wave is reflected, you hear an echo.

we hear an echo because its in our blood to hear things in a repeditive form but a lot quieter.

echo turns into the echo we hear today.

The gaps between the reflections are long when you hear an echo. When the reflections are very close together then you here no single echo, you hear many close reflections as a reverberation.
