The reflecting surface must be sufficiently smooth and shaped such that the sound is reflect back and not dispersed.
Sound travels at approx 340 metres per second and the average human brain easily can distinguish sounds that are 1/2 second apart. That means the sound must travel at least 170 metres so that the reflecting surface must be half that distance away. While a greater distance will create a more distinctive echo, the strength of the returning sound fall off rapidly (at twice the square of the distance to the reflecting surface). In normal circumstances 170 metres (= approx 500 feet) is a good distance. A cave or convex reflecting surface will allow a greater distance.

How long would it take to hear an echo if a cliff is 600 meters away?
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.
Why can you not hear the echo if you stand 20 meter away and shout towards it?
You are too close to the surface from which the sound waves are reflected. As a result you brain cannot distinguish between the original sound waves and the reflexted sound waves (the echo).

What are the conditions for hearing an echo?
To hear an echo, sound must be produced and travel to a surface that reflects it back to the listener. The surface should be at least 17 meters (about 56 feet) away for the echo to be distinctly heard, allowing a delay of about 0.1 seconds. Additionally, the environment should be relatively quiet, and the sound must be loud enough to be reflected back. Factors like atmospheric conditions and the type of surface can also influence the clarity of the echo.
Where would you expect to hear an 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.

What do you hear when sound bounces off the wall?
When sound bounces off a wall, you hear an echo. The reflection of the sound waves off the wall creates a delay in the arrival of the sound to your ears, resulting in the perception of an echo. The size, shape, and distance of the wall can affect the characteristics of the echo.
