Sound secrets

When you visit a building, you usually experience it visually. Modern building acoustics deals with controlling sound in buildings like concert halls and cinema theatres. The fort also has a stone chamber that gives a flutter echo, where small sounds like the snapping of fingers get amplified into loud claps. Scientists who have studied the phenomenon say that the sound ‘creeps’ along the walls by a process of reflection, where it keeps bouncing off the curvature of the walls. We don’t know about the architect of the Gol Gumbaz but the architect of St. Paul’s, Christopher Wren, supposedly never expected this effect when he designed the dome.
