The Relevance Of Acoustic Materials In Terms Of Sustainability

As the field of sustainable design grows and matures, the relevance of acoustics in architecture is paramount, generally subjected to attributes of human comfort and sustainability. With the general faith being instated into the saying, “Quality is more important than Quantity of any built space”, noise abatement is the major issues of sustainable design of built environment focussing the same; because one of the criteria for establishment of indoor and outdoor spaces of good quality is the abatement of noise pollution. Due to bad planning and fastest growth of the city, noise exposure is also rising in the developing countries. But still, acoustics are an aspect of design that has been scarcely ever discussed when the design works well, but they can be a major source of annoyance or worse when there are problems. Since, acoustic comfort is paramount in all kind of environment we live, in that, the major concerns remain to be the low cost and sustainable acoustic design which is influenced by its materials. Poor acoustical conditions can cause unhealthy environment while good acoustics increase the overall comfort level of a space. The aim of this research paper is to present the various essential aspects & attributes of sustainable materials which can be used in the acoustical treatment, with the brief description of the types of materials which absorb and reflect sound, low carbon and natural materials for acoustic treatment with varieties of low-cost materials and also methods to compare the amount of sound insulation from different materials.
