DEAR STUDENT

The ceiling and the wall of an auditorium hall are fitted with sound absorbing materials like wallboard, plasterboard, or gypsum board in order to prevent the sound from bouncing of the ceiling and the wall and causing reverberation.........REVERBERATION is the phenomenon where the sound bounces and overlap or delay causing disturbance..............

reverberation is used in opera to get a good volume for the people and the singer doesnt even have to use a mic
