Architectural Acoustics

By Prof. Sumana Gupta , Prof. Shankha Pratim Bhattacharya   |   IIT Kharagpur
Learners enrolled: 1581
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.

INTENDED AUDIENCE: Anyone can learn from this course.
PREREQUISITES: Basic knowledge of Mathematics, Physics and Architecture. 
INDUSTRY SUPPORT:Architectural Design Firms, Acoustical consultancy companies. The design and consultancy firms can use these lecture modules as a part of the induction programme for their newly recruited graduates.

Instructor bio




Dr. Sumana Gupta is currently working as Assistant Professor in the Department of Architecture and Regional Planning at IIT Kharagpur since 2013. She completed her Master’s degree and Doctoral Degree from the same Institute in 2008 and 2012 with a special interest in transportation planning and service quality evaluation of transport related facilities. Prior to this she worked for fourteen years as a professional architect and as a Lecturer in a Government Polytechnic College in India. She completed her Bachelor degree in Architecture in 1992 from Calcutta University. During her professional exposure as an architect she was involved in Science city auditorium design and presently offers the Buliding Acoustics course to the fourth year architecture students for the last four years.




Dr. Shankha Pratim
Bhattacharya is presently an Assistant Professor in Department of Architecture and Regional Planning, Indian Institute of Technology Kharagpur. He is an Architectural Engineer by profession and having more than fifteen years of teaching experience. He did his PhD on Modeling on Building Structure under Seismic Excitation in 2011. He was Worked as Principal Developer for‘Structural System’ course under National Mission on Education through Information and Communication Technology (NMEICT) of MHRD, Govt. of India. His area of academic and research interest includes earthquake resistant building, building physics and structural systems. Presently he is offering a course on “Building Acoustics” for the undergraduate students of Indian Institute of Technology, Kharagpur. He has published more than ten technical papers in different reputed journals and international seminars.
