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.

Why are multiple echoes heard in an auditorium?
Multiple echoes are heard in an auditorium due to sound reflecting off multiple surfaces, such as walls, ceilings, and floors. Each reflection creates a new sound wave that reaches the listener's ears at different times, leading to the perception of multiple echoes. Acoustic properties of the room, such as its shape and materials, can also influence the presence of echoes.

Why are the walls of Hall auditorium not so smooth?
The walls of Hall auditorium may not be smooth due to the construction materials used, such as textured paint or wall panels, to improve acoustics by reducing sound reflections. The textured surface helps to diffuse sound waves, preventing echoes and enhancing the overall acoustic quality of the space.
What are the situations which echoes can be heard?
Echoes can be heard in environments with hard and flat surfaces that reflect sound waves, such as mountains, canyons, buildings, or empty rooms. When sound waves bounce off these surfaces and return to the listener, an echo is produced.
