The essence of sound is the vibration of the transmission medium, and the eardrum converts it into nerve potential, thereby producing hearing in the cerebral cortex. For each pitch defined by humans, there is an objective frequency corresponding to it, which has nothing to do with the other two characteristics of sound-volume and timbre (the amplitude of vibration determines the volume, and the waveform and the medium of transmission determine the timbre).
Scientific research tells us that every cell in the body is made up of atoms. An atom is basically rotating energy that emits vibrations or fluctuations, which also become frequencies. These electromagnetic waves or frequencies can produce sound, which is measured by Hertz (Hz).
Hertz (Hertz, Hz) refers to the number of cycles per second. Usually, when tuning an instrument, the La (A) sound is used as the basic sound.
Therefore, when we say A=432 Hz, we mean that the La (A) sound wave above the center C (yellow in the figure below) vibrates 432 times per second.
If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.―― Nikola Tesla
Nikola Tesla, a universally recognized illustrious electrical engineer and inventor in human history, once emphasized that vibration and frequency are very important to humans. Although they are invisible forces, they always affect our lives, health, society and the world.
Everything in Life is Vibration―― Albert Einstein
Future Medicine will be the Medicine of Frequencies ―― Albert Einstein
The famous physicist Albert Einstein pointed out vibration and frequencies are very important to human beings. Everything including our bodies, is composed of energy that vibrates at different frequencies.
In recent years, scientists have confirmed the vibratory nature of the universe, and everything has its own specific vibration frequency. As long as people and things with similar frequencies are attracted to each other. Frequency can influence each other, this is a known fact, just like mixing ingredients with other ingredients, it will affect the flavor of the entire cuisine. The way frequency affects the real world has been proven through various experiments, such as Cymatics (Chladni’s experiment to observe resonance) and "memory of water".
Cymatics （also known as acoustic kinetics) is the process of visualizing sound through the vibration of media such as sand or water. The experiment used a metal board, sprinkled some sand on it, and played sounds of different frequencies on it. Observers could clearly see that the sounds of different frequencies made the sand form various patterns on the board. Galileo did this experiment as early as 1630, and later it was carried forward by British physicist, astronomer Robert Hooke, and German physicist, father of acoustics Ernst Chladni. By the 20th century, the anthroposophist Hans Jenny coined the term "Cymatics". Later, British acoustic engineer John Stuart Reid invented an instrument called CymaScope for research in the field of Cymatics.
Cymatics experiments proved that when sound passes through a specific medium such as water, air or sand, it can directly change the vibration frequency of a substance.
Sand changes with frequency ↑
The human body contains 70% water, and the effects of different sounds on water also happen to us, so we can change the state of vibration by the frequency of music. All emotions or thoughts expressed through sound have a certain frequency, just like a drop of water can produce big ripples in a large water area, thereby creating a larger chain reaction.
Masaru Emoto, a Japanese pseudo-scientist and author claimed that human consciousness could affect the molecular structure of water. His 2004 book The Hidden Messages in Water was a New York Times best seller, which showed the world that consciousness can crystallize water through sounds, emotions and thoughts. Although sound is invisible, its vibration can have an impact on matter.
The sound frequency is very important to our human body and health. If we deeply understand and master sound therapy scientifically, we will have better physical and psychological health and achieve greater success in real life.
