Report on REVA Kuvempu and Rangasthala case study

As a part of curriculum, for the subject, Building Services III (Acoustics), understanding the properties of sound and how to control it for Auditorium becomes necessary. For auditorium design, comfortable visibility and proper audibility plays the key role. To experience the function of an auditorium, based on visibility and audibility, students were taken for live case study at Kuvempu auditorium and Rangasthala, REVA University.

At Kuvempu, students observed the placement of various speakers and their function. The Arrey speakers on front covers 70% of the audience, rear speakers with time lag is to enhance the audibility for the last few rows and the feedback-speakers on the stage for the performer or speaker to get feedback on sound quality. Students also checked the angle of vision for the first row and last row seating with the screen placed on the stage. By playing music with various frequencies, students experienced the role of installation of different acoustical materials on wall and ceiling. Each materials has unique ability to absorb sound from low to high frequencies as needed based on performances.

At Rangasthala, it’s been observed that the coupling of spaces with different acoustical need is the major challenge. As Rangasthala is designed for multipurpose activities which need loud speakers, liveliness and high range of sound (dB) emission. On the other hand the classroom surrounding the Rangashala need minimal ambience noise, speech clarity and uninterrupted discussion between teachers and students. It’s been concluded that both the activities can’t be conducted simultaneously.

The live case study of two different types of auditorium will help the students in interpret the pros and cons of various factors need to be addressed while designing an auditorium
