The clarity of communication in any auditorium is closely associated to the quality of acoustic treatment of that space. This quality is characterized by various parameters in acoustic designing. This research paper aims to explain the acoustical phenomenon and defects that becomes the basis of acoustical designing and material selection. The paper includes the basic guidelines and techniques for an auditorium acoustics designing, including fundamental thumb rules for selection of materials with respect to NRC values required in a space. The paper attempts to explain the NRC values that are generally considered on various surfaces of an auditorium to achieve the most efficient sound distribution in the space. Recommendations for surface finish have been conferred to achieve the required acoustical effect in an auditorium.
