The acoustics of the enclosed place make it a whispering gallery where even the smallest sound is heard across the other side of the Gumbaz. At the periphery of the dome is a circular balcony where visitors can witness the astounding whispering gallery. Any whisper, clap or sound gets echoed around 10 times. The ground level samples ring on for a staggering 25 seconds.
You can read the full story of the recording of the samples at the Audioease website.
