This is known as an echo. Echoes are a natural phenomenon that occurs when sound waves bounce off a surface and return to the listener's ears, causing a delay in the perception of the sound. Echoes can occur in various environments, such as mountains, canyons, or empty rooms, where sound waves have a clear path to reflect off surfaces before reaching the listener. Echoes can be used constructively in music production and sound engineering to create a sense of space and depth in recordings.
