Answer 2

In order to make the sound waves parallel and audible from a great distance, a large auditorium has a curved back.

The speaker is positioned at the center of the curved surface, and the sound becomes parallel after reflecting from the curved surface. Curved ceilings and walls allow sound to reflect and reach the intended audience.

This is due to the uniform distribution of sound throughout the hall following reflection. After bouncing off the curved surface, the sound evenly disperses throughout the entire room. In contrast, if the sound wave is reflected from a concave surface, it will converge at a point and this will prevent the sound wave from being easily activated and weakened. The parabolic reflector, also known as a highly directional microphone, is used in the design of parabolic reflectors that are used to precisely focus sound to a point.

In a parabolic reflector, the range of reflected sound waves is at its maximum. The reflected wave only concentrates at a point in a spherical sound reflector when the object is at the center of the reflector's curvature, as opposed to a parabolic reflector, which will focus the parallel waves into a point.
