Because echos are created by sound waves bouncing off of walls, and people and furniture block the walls and the space for the echo to bounce back. If you throw a handball at a wall it will bounce back, but if you throw a handball in a room with a bunch of people it will hit one of these aforementioned people and they will be very unhappy, as they have a right to be.
