because it allows only direct sound to reach the audience .they are even made up of sound proof wall with the concept of two walls and a gap between them so that the sound does not go out and disturb the other people and in another hand to much echo and reverberation makes the sound muddled and we cannot hear anything (dialogues )etc .clearly.therefore , sound absorbing materials are kept in the cinema halls.

Why are concert halls often designed as round or curved auditoriums?
hi erinSimply to improve the way travels throughout the room.The sound of music in halls (acoustics or reverberation) will be altered due to the timing of echoes within the hall and the rate at which they decay away. Echoes with a long delay are generally undesirable and confusing to the ear, so large sheets of hard material (baffle boards) are suspended within the hall and used to reflect sound (make echoes) at short delay times from the stage, rather than allowing the sound to travel as far as the walls or ceiling to create echoes at long delay times. Baffle boards may also be curved in order to disperse echoes to make them less obvious to the ear. Soft absorbent materials are used to prevent echoes from distant parts of the hall which might otherwise create echoes with long delay times. The soft furnishings of seating, carpeting and even the people in the audience will absorb sound and reduce echoes. The essential quality of a concert hall is called the "reverberation characteristic" which is a measure of the timing of the echoes and the rate at which they die away. In a concert hall, a certain amount of reverberation is desirable and pleasing to the ear, while in a recording studio reverberation is prevented as much as possible. Concert halls are regarded generally as having "lively" acoustics while recording studios are regarded as having "dead" acoustics.
