Acoustic modelling and simulation of Indian stepwells: Panna Meena ka Kund and Lahan Vav

This dataset consists of the architectural models, simulations and associated analyses used for a study of acoustic retroreflection in Indian stepwells. The concept is that the concave trihedra formed by a large number of steps form an array of retroreflectors, which concentrate reflected energy onto the source position. Simulations were performed using the finite-difference time-domain method. Most of the simulations are of two stepwells, Panna Meena ka Kund and Lahan Vav. Data is mostly using MATLAB file formats.Architectural models were made using Rhino, based on published architectural drawings. Finite-difference time-domain simulations were done using a high capacity computer, using custom-written code hosted in MATLAB. Further analysis was done in MATLAB
