Sound will echo in an empty room because if there is nothing to stop the sound from reflecting between hard surfaces, such as the walls, windows, ceiling, and floor . Since each surface is not a perfect reflector, some of the sound energy will be absorbed by the surface.
Why do rooms echo when empty?
An echo is going to occur in a room when sound waves are reflected back.

Why do some rooms echo more than others?
Bathrooms and showers tend to echo based on the hard surfaces that repel the noise. Tiles, glass, and other hard material that doesn’t absorb noise often cause a frequent bounce and vibration of the voice. This creates an echo and can be heard from several rooms over.
What absorbs sound in a room?
Insulation fills the gaps between walls and the spaces between studs, absorbing noise and breaking the path of sound. To stop noise transfer between rooms use it in both interior and exterior walls.
Does opening windows reduce echo?
Does opening a window reduce echo? The window can transmit 100% of acoustic energy coming towards it. So yes, an open window will reduce echo in the room. However, one should have more sound-absorbing materials if the room has high ceilings and wooden floors.
How do I stop the echo in my high ceiling room?
Removing echoes Install acoustic tiles on the tall ceiling. One way to vastly improve the sound quality in a room that echoes because of high ceilings is to have the ceiling itself absorb some of the sound waves. Hang objects on the walls of the room. Lay carpet or rugs on the floor. Fill your room with more objects.
What is a dead room in acoustics?
DEAD ROOM. A room is said to be acoustically ‘dead’ when it contains a great deal of sound absorbing material, such that there is little or no REVERBERATION, and strong ATTENUATION of high frequencies. The extreme of this situation is the ANECHOIC CHAMBER. Sound in a dead room will be dull and lack PRESENCE.
What causes reverberation?
Reverberation is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air.
Why do we hear echo in empty hall and not in well furnished room of the same size?

Does fabric absorb echo?
Choosing materials like wood, metal, or leather can do a little to scatter sound waves but don’t do much as far as absorbing waves. Although you don’t need to avoid wood and metal entirely, the fabric upholstery is your friend when it comes to decorative sound absorption.
Do plants reduce echo in a room?
Refraction – Refraction is taking away the echoes of the sound bouncing off the hard surfaces. Plants will help to refract this noise and eliminate the echoes which are responsible for much of the added noise in your home or office.
