After many years of interest of the subject of paranormal and anomalous things, I made one conclusion: it all comes down to vibration.

So when you can make the conclusion that everything is vibration, then a part of this vibration is also sound

So there is a reason behind it that you are forbidden to speak some words, like the real name of God in hebrew (Yeh'vah). In other cultures it is just the opposite, you have to say the word for enlightment, for example in hindu (hare krishna)

I have read many stories about levitation (the ability to fly or to fly objects around) which are connected to sound. A famous example from this time is Coral castle (28655 S. Dixie Hwy. corner of U.S. 1 & SW 286th St. Homestead, florida, USA). This was build by one man in some 20 years, while nobody knows how he did that. There is one theory which says that his love ,for who he build the castle, which he called 'sweet sixteen' was a reference to the number Phi (1,6.....).

Also the normal human functions have a frequency, like a heartbeat. Try to hum for yourself loudly. Then you will see that a certain hum will work on a certain part of your body.

So it is very logical to make the shift to higher aspect of the human with sound. Could it be possible that sounds can put you in a certain mindstate? I think that is proven already, given the fact that people can learn better while listening classical music. Also a brainmachine can do a lot to your state of mind.

For those reason I came to the conclusion that secret Holy sounds are one of the keys to higher consiousness, and that the cristian dogma of 'just say the name of Jesus' is actually true. This is an example how real ancient things can get through in 'modern' times. The only problem is, what is the original exact sound of these words? some examples are YHVH, KRSNA, GABRIEL, AUM.

There are people who calculated the 'cosmic sounds'. This is an example of how the sound for the day is calculated (The working of this tone would be revitalizing):

Elapsed time for a day:
1 Day = 86400 Seconds (24h x 60m x 60s).
So that is in Hertz (Hz = waves per Second):
1 : 86400 Seconds = 0,000011574 Hz
Double this frequency until you are in a frequency-range detectable by the ear (roughly 20 Hz - 20 kHz):
By doubling the frequency you are adding one octave.
0,000011574 Hz x 2²⁴ = 194,18 Hz
(2²⁴ meaning the frequency doubles 24 times, so this sound is 24 octaves up).

Note the fact that a day is not always a day, since you have siderial or solar days (siderial is measured against the stars, and since the earth moves around the sun this day is a bit shorter than the solar day, measured against the sun). When you take a day not for 24 hours, but 23 hours and 56 minutes (the siderial day) and recalculate as above, the frequency would be 217,096 Hz. The difference of 22.9 Hz is very good detectable for the human ear, so it sure is something to consider. But since this tone-theory exists for a long time now (thousands of years), it must be useful in some way for humans.

So we can ask yourself if one need to hear an exact tone. Because nature also never follows the rules of the fibonacci sequence exactly, so i suppose the right tone also differes from human to human.

There is a scientist who studies the relationship between sound and certain shapes by letting the sound work on a plate which contains sand. Beautiful nature- like patterns appear. see here. Very curious: This scientist also noticed that when the vowels of the ancient languages of Hebrew and Sanskrit were pronounced, the sand took the shape of the written symbols for these vowels, while our modern languages, on the other hand, did not generate the same result.
