Which of the following best describes the effect of excessive reverberation in a large auditorium during a speech?
It causes spoken words to overlap and become unclear to the audience.
Reverberation is the persistence of sound in a hall after the source has stopped, caused by repeated reflections from walls, ceiling and floor.
In a large auditorium, syllables of a speech overlap with the reflections of the previous syllables, so words blur into one another and become hard to understand.
Hence, the answer is It causes spoken words to overlap and become unclear to the listener.
