Echoes are occurring all the time. During a normal conversation with others in
your 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're
not aware of them, because the time delay between the original sound and the
echo 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 is
0.05 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.

What is the minimum distance of the obstacle from the source to hear an echo?
The minimum distance for an echo to be heard is approximately 17.2 meters (56.4 feet) from the source. This accounts for the time it takes for sound to travel to the obstacle and then reflect back to the source for the echo to be perceived.
How does sound produce an echo?
When sound waves hit a hard surface, such as a wall or a cliff, they bounce off that surface and return back to the listener's ears. This reflection creates the sensation of hearing the sound again after a slight delay, which is known as an echo. The distance between the source of the sound and the reflective surface, as well as the distance between the surface and the listener, determines the time delay and strength of the echo.
What wave interactions produces an echo in a canyon?
Sound waves interacting with the canyon walls can produce an echo. When a sound wave hits a wall, it reflects back towards the source creating an echo. The distance between the source of the sound and the reflecting surface determines the time delay between the original sound and the echo.
What two factors affect the clarity of an echo?
The distance between the listener and the reflecting surface, as well as the reflective properties of the surface, can affect the clarity of an echo. The further the distance and the more absorbent the surface, the less clear the echo will be.
How does loudness of an echo in echolocation affect distance?
To our knowledge, the amplitude of the echo isn't used in the determination ofthe range to the target. The amplitude depends on the size, shape, and surfacecomposition of the target, so it's not a reliable indicator of the distance. The distanceis determined primarily by measuring the time delaybefore the echo returns to thesource of the sound.
What is the minimum distance required to produce a distinct echo in meter?
17.2m
What is the minimum distance to get an echo?
Depends on the quality of the sound. The minimum distance to hear an echo will be partly based upon the observers ability to resolve different sounds (i.e. so that they can distinguish between the actual noise, and the arrival of the reflected sound - a little 100 year old lady may not be as good as a 15year old!). This will vary between observers, as their auditory reaction times vary In the perfect Physics world though: Assuming a sharp sound (like a gunshot) the minimum distance (d=vt) to hear distinct echo is 17.2m considering the speed of sound to be 344ms. In general the "minimum echo distance" is always equal to half a wavelength from the reflector.

What is echo define and explain with examples?
Echo is a delay of sound - it comes at a slower rate and appears to echo. Often distance is a major factor of echo.

Where are examples of places where you might produce a good echo?
in a cave
What is echo and its application?
echo is nothing but the reflection of sound and it is used to find the distance of certain places like mountains and buildings.
What is the minimum distance allowed near open trenches when travelling a crane and why?
The minimum distance is the depth of the excavation...
