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.
