why do we use curved screens behind the stage of any hall and not the straight ones?

Expert Answer:

A sound board, which is a curved sound reflecting surface, is placed behind the stage. The source of sound is located at the focus of this reflecting surface. Sound waves coming from the source become parallel after reflection from the sound board and spread evenly throughout the width of the hall.
