Because your brain receptors are very well tuned.
In an empty room, sound waves bouncing off the walls are not absorbed as much, resulting in clearer echoes. In a full room with objects and furniture, sound waves are absorbed and diffused by the objects, reducing the echo effect.
In a furnished room, the presence of furniture and other objects helps to absorb sound and reduce echoes, resulting in clearer acoustics. An empty room, on the other hand, tends to have more reverberation and sound reflections, which can make it more challenging to hear clearly.
In general, an empty room will have more echo than a furnished room. This is because the furnishings in a room can absorb sound waves, reducing reflections and echo. Items like furniture, curtains, and rugs can help dampen sound and create a more acoustically pleasing environment.
An echo is the reflection of sound waves off hard surfaces, causing them to bounce back to our ears. In an empty room, there are fewer objects to absorb or dampen the sound waves, allowing them to bounce around more easily and create an echo effect.
There is no where for the sound wave to reflect

If you are signing in an (otherwise) empty room the sound will echo around you and will possibly sound high-pitched. If you are signing in an empty room then the room isn't empty.

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!
Sound waves travel in airThey bounce off of pretty much everythingIn an empty room they bounce off walls and create a echo

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.
#!/bin/sh [ -s $1 ] && echo "not empty" [ -f $1 ] && echo "empty" echo "not a file"
we hear an echo because its in our blood to hear things in a repeditive form but a lot quieter.
