Eco, in this context, refers to echoes. The minimum distance between the point where a sound is produced and the reflecting surface should be sufficient to hear a distinct and clear echo. This distance depends on factors like the intensity of the sound and the acoustics of the environment.
This sound which we hear is called an echo. Echoes are heard due to the phenomenon of Reflection of sound waves. To hear the echo clearly, the reflecting object must be more than 17.2 m from the sound source for the echo to be heard by a person standing at the source.
