Sounds seems to echo in an empty room because the sound has only six surfaces to bounce off of. When the sound waves bounce, they bounce right back to the source. However, when there is furniture, pictures, and other objects placed in a room, those surfaces contain just about every different angle, and when sound hits them, they bounce every but back to the source, hence, little to no echo.
