Abstract:
Abstract- Some ancient constructions over the world exhibit acoustic resonance chambers [1, 7]. Acoustic resonance of
Pyramids [1], Stupas [2,6,7], Cathedrals [3,4,12] and Mosques [5] have been studied and they closely resembles the Alpha,
Theta and Gamma waves of EEG spectrum [11]. Moreover, these EEG frequencies corresponds to the alert calmness that
conducive for mental composure and general well being [6, 7]. Research has also showed that these frequencies are also closer
to the Shumann resonance frequencies [9,10]. Even though, acoustic resonances are in the mechanical vibration domain the
researchers have found these vibration energies may have transformed into equivalent electromagnetic frequencies (EEG and
Shumann bandwidth) [1,6]. This conversion is mostly may have achieved in ancient resonance chambers by properly using
special quartz crystals [2,6,7] and getting them to vibrate by acoustic energies. In addition, some of these acoustic resonance
chambers also have vibrating frequencies which are octaves of 528 Hz and 432 Hz [13]. These frequencies are also known to
be healing frequencies commonly used in sound therapies [14]. Limited research has been done to understand the acoustic
resonance chambers of Hindu Temples. Two types of acoustic resonance chambers can be found in Hind Temples. The first
one is the “Moolastana” chamber and the other is the inner core (path). We have studied, and measured acoustic resonance
frequencies of inner core chamber in a Hindu Temple in Sri Lanka
