Can you prouce echo in a room?
Nothing to it. You do that every time you speak in the room. You just don't notice it, because the delay is so short. Even if you're 20 feet from a wall, the echo returns to you in only about 0.036 second, which is too soon for your hearing system to notice it. The nearest that a reflecting surface can be in order for you to notice the echo is about 60 feet away (for 0.1 sec delay). Most rooms are not that big.
An echo is heard when a person shouts in a canyon and the sound waves are?
When the sound is reflected.
What is the minimum distance to produce an echo?
Echoes are occurring all the time. During a normal conversation with others inyour home, the sounds of the voices are reflecting off of the ceilings and walls,often bouncing back and forth from several surfaces before fading away. We'renot aware of them, because the time delay between the original sound and theecho is so short.Let's estimate that the minimum delay-time that a person can notice is 0.1 (one tenth)of a second. That delay is introduced when sound is reflected from a surface that is0.05 second away (so that it takes 0.1 second to go there and come back to you),or roughly 50 to 55 feet from you.
Why does an echo occur?
Sound waves reflect from objects. This is the echo. But a smooth surface and distance is required for this to occur. Sound moves at 343 meters per second in dry air at 20 degrees so if you make a sound and hear an echo 3 seconds afterwards the structure that reflected the sound is 1029 metres away. A distant wall, cliff, etc can act like a mirror to sound. Sound travels much slower than light ( 1715 metres in 5 seconds) so you get the sound wave back after a delay.
How long does a sound take to come back as an echo?
it takes about a second or two for a sound to come back as a echo

What is sound echoes?
In audio signal processing and acoustics, an echo (plural echoes) is a reflection of sound, arriving at the listener some time after the direct sound. Typical examples are the echo produced by the bottom of a well, by a building, or by the walls of an enclosed room. A true echo is a single reflection of the sound source. The time delay is the extra distance divided by the speed of sound.">In audio signal processing and acoustics, an echo (plural echoes) is a reflection of sound, arriving at the listener some time after the direct sound.
