An echo occurs when sound waves reflect off a surface and return to the listener after a delay. This typically happens in large, open spaces where there are hard surfaces, such as mountains, buildings, or walls. The time it takes for the sound to return depends on the distance to the reflecting surface; a longer distance results in a longer delay. For an echo to be distinct, the delay must be at least 0.1 seconds.

A bounced sound wave is called an echo. It occurs when sound waves reflect off surfaces and return to the listener's ears after a brief delay.
An echo is an example of reflection, which occurs when a wave bounces off a boundary. In the case of sound waves, an echo is produced when sound waves reflect off a surface and return to the listener.

A returning sound is typically referred to as an echo. This occurs when sound waves bounce off surfaces and return to the listener's ears after a slight delay.
The term used to describe sounds that are reflected back to their source is "echo." An echo occurs when sound waves bounce off surfaces and return to the listener's ears after a delay.
A reflected sound waves is called an echo.
Echo-back interferes with the original signal
Reflected sound is called an echo. This occurs when sound waves bounce off surfaces and return to the listener's ears after a short delay, creating a repetitive sound effect.
An example of an echo is when you shout in a canyon and hear the sound bounce back to you. This occurs because the original sound wave reflects off the canyon walls and returns to the source.
