The reflection of sound is called echo.

echo is heard only when surfaces are far away.it is because the ears cannot distinguish between the two voices when sound is reflected from a nearby surface .This phenomenon is most commonly observed on the hills . The echo is very clear when on hills .

An echo is a sound that returns to its source like a boomerang. In order to return back in the direction of its source, a sound or light wave must either trace a path in space that is reminiscent of a parabola (like the curvilinear motion of light traveling around the sun as a consequence of the curvature of space itself due to the sun’s gravity, as predicted by General Relativity) or simply, reflect from a surface. An echo is the latter, it is a reflection of sound waves from objects in the vicinity of the source.

Yet, if an echo is merely a reflection of sound, why don’t we hear them in small rooms, where there are even more surfaces to reflect from? The answer lies in how the human brain perceives sound.
