If the echo is off of a wall or a cliff, then it's about 170 meters (186 yards)
away from you, but the echo can't tell you how high the wall or cliff is.
Conversely, if the echo is off of the ceiling, then you are in a truly huge cavern. It would be highly unlikely that there would be a ceiling 170 meters high, but it is possible. More unlikely still would be a building with a ceiling that high.
If it takes 15 seconds for an echo to be heard, the distance between you and the reflecting surface (such as a wall, cliff, or building) is approximately 2,250 meters (15 seconds multiplied by the speed of sound at sea level, which is about 343 meters per second).
To calculate the time it takes to hear an echo from a cliff 600 meters away, we first need to consider the speed of sound, which is approximately 343 meters per second in air. The total distance for the sound to travel to the cliff and back is 1,200 meters (600 meters to the cliff and 600 meters back). Therefore, the time to hear the echo is 1,200 meters divided by 343 meters per second, which is about 3.5 seconds.
we hear an echo because its in our blood to hear things in a repeditive form but a lot quieter.
echo
sound is reflected when it strikes at any medium. a distant sound becomes clear if echo or reverbation takes place. an echo happens when one hears the reflection of the original sound 0.1 seconds later. and reverbation is multiple echo, which one can hear in sikandra at agra in india

The echo you hear after shouting in a gym is caused by sound waves reflecting off the walls and bouncing back to your ears. This delay in hearing your voice is due to the time it takes for the sound waves to travel to the wall and back.
You can hear your echo in an open space because sound waves bounce off surfaces and reflect back to you, creating a delayed repetition of the original sound. The time it takes for the sound to travel to a surface and bounce back determines how far away the surface is from you.
They can't they only have an echo hearing! When they hear something like a pray the location where it's staying can echo further than a mile! That's how good they are at hearing than seeing!
