1.0 AUDITORIUM DESIGN An auditorium is designed to achieve effective projection of sound to the rear of the auditorium so that distant listeners do not suffer extreme loss of sound level caused by the inverse square law. This projection is normally achieved by having a sufficiently long reverberation time. The inverse square law is any physical law that states that a given physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. Another significant addition to this design is a high, reflective ceiling to reflect sound to the rear of the auditorium. To achieve the goal of crisp clarity of original sound for every audience member regardless of seating position, quality soundproofing for the space is crucial to ensure that every word is understood and the music is delivered with great harmony. 2.0 ACHIEVING SOUND CLARITY To achieve sound clarity, the materials needed for sound insulation should be decorative; durable; fire class “A”; capable of absorbing the reflections of sound waves; check background noise; disperse sound waves to produce greater balance; and exposure to sounds emitted from the stage. Acoustic panels used to soundproof an auditorium capture and convert unwanted background noise, reducing reverberation time to less than 2.0 seconds. This produces better speech clarity for the audience and helps balance the tones produced by the musicians. The diffusion panels used help disperse noise to provide better diffuse balance throughout the room regardless of seat position. Although the richness given by the reverberation of the auditorium is des...... middle of paper ......ght /ch26sound/ch26sound_images/ch26_images.html>Auditorium, noise control - soundproofing, accessed on 21 April 2014.< http://www.controlnoise.com/auditorium-soundproofing/>Hyperphysics – Architecture for Acoustics, accessed April 21, 2014.< http://hyperphysics.phy-astr.gsu.edu/hbase/ acoustic/arcaco.html >Multipurpose auditorium, accessed on 21 April 2014.
