It is difficult to say how far the human ear can pick up sounds. The distance a human ear can hear varies according to the condition of the ear, the frequency of the sound, and other sounds taking place at the same time.
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.
A person can hear an echo of sound in locations with hard and smooth surfaces that can reflect sound waves, such as caves, mountains, canyons, or buildings with high ceilings.
The Grand Canyon.
The distance sound travels before you hear an echo depends on various factors such as the environment and the surfaces it reflects off. Generally, sound can travel up to approximately 17 meters (56 feet) before the echo becomes noticeable.
If a person is in front of a smooth surface from which a sound is reflected, the person would hear a sound that ====================================================== Allow me to add(: SEEMS TO COME FROM BEHIND THE SURFACE:>
An echo is heard when a person shouts in a canyon because the sound waves reflect off the canyon walls and back to the listener's ears with a slight delay. This delay is what creates the perception of an echo as we hear the original sound followed by its reflection.
the answer is c. at least 16.6 meters in front of the reflecting surface!
An echo occurs when sound waves bounce off a surface and return to your ears. You hear an echo when the time delay between the original sound and the reflected sound is long enough for your brain to perceive them separately. If you shout in one particular direction, the sound waves need to travel a sufficient distance before bouncing back to you to create that noticeable delay and produce an echo.
There is no where for the sound wave to reflect
When a sound wave is reflected, you may hear an echo or reverberation of the original sound. The reflected sound wave can create additional auditory cues that can affect how the sound is perceived in the environment.
When a sound wave is reflected, you might hear an echo. The reflected sound wave can arrive at your ear slightly after the direct sound wave, creating a delayed repetition of the original sound.
when you produce sound, and it hits a barrier, and reflect back. echo is hearing the sound again after the vanish of the original sound. you can only hear it if these two reasons are satisfied: 1) the barrier should be wide (large) enough. 2) distance between source of sound ( the observer) and the barrier is 17 meters or more. OR The easiest answer is that you hear echo by your own ears. DONE BY AHMED HUSSIEN and i thank mr. Ahmed my physics teacher... because without him i wouldn't of had these information....
