(Newswire.net — March 1, 2015) — Since the International Standards Organization (ISO) promoted it in 1953, standard audio tuning was at 440Hz frequency. That means, the A note of the instrument is tuned to 440Hz and all other notes are tuned accordingly. However, researchers discovered that more perfect wave sound comes from 432Hz tuned music.
In a simple experiment, the square plate was attached to the sound generator and it vibrated differently depending on the sound frequency. The way the plate vibrates is how it emits the sound waves. When light granulated material is spread on the plate, light sand for example, the sound waves becomes visible as the sand creates different patterns. An experiment showed that 432Hz tuned sound waves actually create more beautiful and geometrically complete patterns than 440Hz tuned waves. The experiment is so simple it can be executed at home by attaching a thin metal plate to a speaker.
Does it really matter?
According to acoustic and audio engineer Trevor Cox, Professor at the University of Salford, 432Hz and 440Hz were rated with equal preference. He conducted a survey in which he asked participants which audio they preferred. He said the survey results showed that the likeness of an audio does not correspond with the 440Hz-432Hz change.
Another research study gave different results. Through the 1990’s, Japanese scientist Dr. Masaru Emoto performed a series of experiments observing the physical effect of words, prayer, music and environment on the crystalline structure of water. He exposed perfectly measured drops of water to some positive and to some negative acoustic vibrations. Basically, he sweet-talked to some of the drops and cursed the other drops.
DR. Emoto then froze the drops in a laboratory under the exact same conditions. The results were nothing short of remarkable, as the sweet-talked drops crystalized creating the beautiful symmetrical shapes, while the cursed drops gained ugly asymmetrical form, as if they didn’t develop at all.
Giving that the human body mainly consist of water, we can imagine how our surroundings affect us.
The sound does matter, we all know that. Some music we can listen to for hours and other music we become annoyed in seconds, but what about beautiful music that differs only by frequency tuned from 440Hz to 432Hz?
Composer, educator and audio researcher, Brian T. Collins, said that from his observations, “some of the harmonic overtone partials of A=432hz 12T5 appear to line up to natural patterns and also the resonance of solitons. Solitons need a specific range to form into the realm of density and span from the micro to the macro cosmos. Solitons are not only found in water mechanics, but also in the ion-acoustic breath between electrons and protons.”

“What we have called matter is energy, whose vibration has been so lowered as to be perceptible to the senses. There is no matter.” – Albert Einstein
So, do we need to retune our instruments or retune the music we listen to with audio software, it is entirely up to us. Personally, I find some music does sound more appealing retuned to 432Hz. However, I find Vivaldi’s ‘4 Seasons’ more appealing tuned to the standard 440 Hz.
The answer is, as always, somewhere in between.
