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.

You would expect to hear an echo in places that have hard and flat surfaces such as canyons, mountains, empty rooms, or hallways. Sound waves bounce off these surfaces and return to the listener after a slight delay, creating the echo effect.
When sound bounces off a wall, you hear an echo. The reflection of the sound waves off the wall creates a delay in the arrival of the sound to your ears, resulting in the perception of an echo. The size, shape, and distance of the wall can affect the characteristics of the echo.
It is a reflection.
When a sound wave is reflected, you may hear an echo or reverberation of the original sound. The reflected sound wave can create additional auditory cues that can affect how the sound is perceived in the environment.
A person can hear an echo of sound in locations with hard and smooth surfaces that can reflect sound waves, such as caves, mountains, canyons, or buildings with high ceilings.
we hear an echo because its in our blood to hear things in a repeditive form but a lot quieter.

Duck quacks do echo.It is a scientific myth that a duck's quack does not echo. Research has shown that a duck's quack does echo, but it is hard to hear because it is difficult to distinguish the quack from the echo.There are several reasons why it is difficult to hear the echo:Echoes are produced after loud noises. Ducks quack very softly, so the reflected sound is difficult to hear.A reflecting surface is needed to hear an echo. Ducks tend not to live near reflecting surfaces such as cliff faces or buildings. An echo could be heard more readily if the duck quacked whilst flying past such as surface.

You can go into a stuffed small room and not hear an echo unlike moving into a new big house with no furniture! there would be a big echo!
