This article presents the study of acoustics of the Deekshabhoomi, a Buddhist monument, with an imagery and external form of the Stupa in Nagpur, Maharashtra, India. It is one of the large hollow Buddhist Stupas in the world, with religious activities such as meditation, chanting, and sermons being delivered associated with it. The aim of the research was to assess the acoustical behavior of the space. The research includes in situ measurements at the monument, in an unoccupied condition. The virtual simulation models were then built which were validated with the in situ measurements in the unoccupied condition. These models were further simulated and analyzed for both occupied and unoccupied conditions. The average reverberation time of 5.6 and 9.7 s has been reported at mid-frequencies for occupied and unoccupied conditions, respectively. The article also compares other worship spaces of different religions, like structures with similar nature of the reverberant field, as less research has been done on hollow Buddhist Stupa. It explicates the acoustical condition present in the monument, and its impact on the Buddhist chanting and other religious activities.

Abstract:The heritage landscape of Burhanpur has an architectural and horticultural composition, consisting of many historic gardens, a unique water management system, a sustainable planning and design framework, the use of landscape and topography with numerous heritage components and historical monuments, temples, tombs and mosques that are locally, regionally and nationally significant. Conserving Burhanpur as an inspirational model for other sites is not only a cultural heritage objective, but it is also a crucial component of the heritage-based sustainable regeneration of the landscape, because it is directly linked to environmental integrity, economic efficiency and resources for present and future generations. Although the last decade has witnessed vigorous efforts by the municipal corporation to preserve and develop Burhanpur by designating it as one of the heritage cities of the UNESCO-Indian Heritage Cities Network (in 2006), a coherent, holistic and sustainable heritage outcome has not been achieved. This paper proposes to harness the cultural landscape as an approach for the sustainable regeneration of Burhanpur heritage and takes a holistic approach to the interpretation of the historic district and natural landscape of the city, where historic buildings are located.
