Reverberation and Echo 05 best difference you should know

Reverberation and Echo

Reverberation and Echo are two acoustically related phenomena involving soundwave reflection from surfaces within an enclosed space, respectively. Reverberation refers to persistently decaying sounds due to multiple reflections from surfaces throughout an enclosed area while echo is caused by sound waves striking surfaces before reaching their intended destinations. Enhancing a sense of space, echo is often found in concert halls and recording studios, often due to reflections off distant surfaces that cause it to repeat with noticeable time delays.

Conversely, resonance refers to any continuous repeating sound caused by reflection. Reverberation creates the sensation of distance and depth and is common in natural settings such as canyons or mountains.
