There are chambers uncovered that were made by early man that have this resonance frequency. Caves that were carved out, and stone structures built specifically to resonate specific frequencies.
True story ... When I was separating/retiring from the Army I had developed high blood pressure. Doc put me on meds. I don't do meds so I researched non-pharma solutions and found binaural beats (432hz). In one week I trained my body to 'decompress' in a matter of minutes. My doc (who was awesome by the way) was skeptical but intrigued, so we did a 'micro trial' right there in his office. I lowered my BP from 188/105 to 135/80 in 3 minutes using breathing and binaural beats at 432hz. This is now something I do twice a day simply out of habit. Its easy as hell and I swear by it. It's real, and it works. 432hz and purposeful deep breathing exercises.
My wife says I'm a little obsessed with sound :) I'm always either copying sounds, or making some kind of noise :) One thing I like to do, is find the resonant frequencies of a room. If you start out with a low hum and gradually increase the frequency, you will hear the resonant frequencies; your hum is amplified by the room. I imagine that the music venues that are known to have "excellent acoustics" are probably resonant to frequencies that are most pleasing to humans. (but some rooms are too irregular or have too many things to do it, but it definitely works in a small room like a bathroom :) )

Oh. I do this too! our semi enclosed bath / shower has several resonant frequencies.
