I got this question during an interview.

My doubt is from Acoustical Design of Halls and Studios topic in chapter Acoustics and Ventilation of Construction & Building Materials

Answer 1

Right answer is (c) 100

The best I can explain: In the acoustical design of a hall or an auditorium, the angle between the side walls and the curtain line should not be more than 100 degrees. The shape of the hall is an extremely important factor in view of better audibility.
