The lectures will be oriented towards the students of architecture and will highlight on the evolution of acoustical science and its application in design and planning until today. The fundamentals of acoustics are an essential component while designing specific spaces small and big like recording studios, class rooms, lecture halls, auditoriums. The Architectural Acoustics course is broadly classified into three sub sections and comprises of 8 modules: After introduction to the course the lectures will be on sound physics. Lectures will include various characteristics of sound, its origin, propagation and auditory sensation and the measurement techniques. Difference in behaviour of sound in closed and open spaces and the mathematical calculations will also be covered. The primary focus of the second part is on acoustical design of spaces which includes room acoustics, understanding the phenomena of reverberation and sound absorption and finally design spaces where the primary purpose is related to achieving good sound quality. It includes small spaces like class room to lecture halls or large spaces like cinema halls and auditorium. The third subsection of the course will cover the aspects of environmental noise control - both air borne and structure borne.
