Analytical Survey of Acoustical Material’s VOC Emission and its Installation in Auditorium

Abstract

Human being is a social animal and from the ancient times, gathering spaces are playing an important role in our society. Indoor and outdoor spaces were built for social gatherings like open air theatres, multipurpose halls, auditoriums, religious places like temples, Mosques, Churches etc.
Auditorium is a hall or large building used for stage performances, public assembly or speeches. In auditorium there is need to get acoustical treatment properly. Basic acoustic criteria for all types of auditoriums are the same. It should have low ambient noise level from internal & external source, appropriate reverberation time, Avoid echoes, flutter etc. To full fill these criteria appropriate acoustical material for floor, ceiling & wall is necessary. Contemporary acoustical materials, paints & adhesive use for auditorium emit some amount of VOCs (Volatile Organic Compounds). High VOC content materials decrease productivity of occupant and also cause illness. Exposure to VOCs in indoor environment can causes indoor air quality related problems. It is essential to study VOC emission of different contemporary materials and suggest appropriate materials for floor, ceiling and wall of auditorium. In this paper, Acoustical materials along with VOC emission, Absorption coefficient for different frequencies & installation techniques have studied & analyzed various types of materials and installation techniques can be used for floor, wall & ceiling of auditorium.
