What do we call the lasting of sound caused by repeated reflections?
Reverberation
Reverberation refers to the lasting persistence of sound caused by multiple repeated reflections within an enclosed space.
Quality, Echo and Resonance describe different sound-related phenomena, with echo specifically being a single distinctly delayed reflection.
Hence, Reverberation is the correct answer.
