This post is about architecture and engineering and construction. I want to emphasize that. Eastern Culture has for centuries believed in beneficial aspects of meditation and chanting Mantras. The idea of chanting a Mantra such as "OOOM" repeatedly is that it vibrates/resonates your body to a frequencies that are allegedly conducive to good health, etc. If this is true... (This is not a debate on eastern philosophies) A room that could resonate with sound as well as broadcast the sounds with enough volume inside to replicate the experience might appeal to some of us silly westerners who are too lazy to meditate, or even meditate often. If you had to construct a device how would you do it? My first thoughts are personal units where a plastic encasement would enclose a person from the head down, while a chorus of Tibetan monks gave the required mantra through high volume speakers inside the case. I am thinking; neck down, so as not to damage hearing. Perhaps a understanding of anatomy and studies to show the amount of inner vibration that accompanies such chanting would be necessary. Would the device be better suspended by springs? Would the device be better made of materials that resonate such as high quality spruce like in violin construction? Would the device need to be certain dimensions to allow for various wavelengths to flow, or would the concussive force from the speakers alone be better? I know it sounds somewhat kooky, but alternative healing is becoming big business.
