Sound Hypnosis – What is 432 Hz?

Sound Hypnosis – What is 432 Hz?featured

432 Hz is an audible sound frequency that is one quarter-tone flat of concert pitch “A”, 440 Hz. To a non-musical ear, it just sounds like quite a high tone, but there is far more to the 432 Hz frequency than it’s musical qualities. It was a fundamental aspect of pre-pharmaceutical healing, and is making a come-back in modern sound hypnosis. Understanding the importance of the 432 Hz frequency does not require any musical training or a “musical ear”. This frequency was important to many ancient cultures including Sumerian, Indian, Tibetan, Egyptian, and Greek.

What is 432 Hz and why is it important?

Just as there are irritating and even harmful sound frequencies, there is a system of frequencies that is harmonious with the human body, and the system survives despite the best efforts of the Chinese annihilation, in modern Tibet. Don’t be put off by the chakras, they are not mysterious. Chakras are the Vedic (ancient Indian) descriptions of collections of nerves or ganglia in the body. We dismiss at our peril the observations of Vedic medicine, that interferences or irregularities in the body’s electro-magnetic field indicate the risk of illness, and are most easily discernible in the ganglia and the brain, where nerve endings are more dense than in the extremities. 432 Hz is the frequency of the Crown Chakra’s electro-magnetic field, and the “A” of the Vedic tonal system. (Vedic knowledge travelled to Tibet with the spread of Buddhism in the 8th centuary CE.) Using the Tibetan / Vedic tonal system for the chakras, we can produce the correct frequencies for the healthy electro-magnetic field of each chakra, as a sound. Tibetan singing bowels are handmade for this express purpose, but modern software can be equally efficient and highly accurate. When the sounds are produced by speakers, headphones, or acoustic instruments, each of the body’s principle nerve centres including the brain vibrate in sympathetic resonance with the correct frequencies and return to a healthy electro-magnetic state, preventing problems before they can escalate into illness.

If the same notes are based on the concert pitch A at 440 Hz, the range of frequencies does not match the healthy electro-magnetic fields of the chakras, and does not have the same effect on the body.

How sound vibrations effect the body

Electromagnets are used both to record sound (microphone) and produce sound (speakers) using the principle of resonance – sound waves cause an object or body in the near vicinity to vibrate. This can easily be observed by standing close to a bass speaker and feeling the vibration in your body. On a more refined level is the related principle of sympathetic resonance, which occurs when a sound frequency exactly matches the resonant frequency of an object or body in the near vicinity. Quite a famous example is the ability of a powerful singer to shatter glass by singing the exact note at which the glass resonates (578 Hz to 1202 Hz, depending on the glass). Sympathetic resonance is also responsible for the beautiful ethereal sounds produced by many musical instruments such as the Indian sitar.

When the resonant frequency of a chakra is produced as a sound, the electro-magnetic field generated by nerve activity in the ganglia of that chakra resonates sympathetically with the sound frequency being produced, and the nervous system returns to a healthy state.


How sound hypnosis works

The brain is part of the nervous system and very much effected by sound vibration. (Light is also vibration – but we’ll come back to that.) Back in 1839, scientist W.H. Dove made two significant breakthroughs in psychoacoustics:

  1. Binaural Beats – Hearing specially prepared sound frequencies with headphones, one to each ear, and one slightly higher than the other, the brain perceives a “binaural beat” that results from the two sounds.
  2. The Frequency-Following Response (FFR) – The brain can easily “follow” the binaural beat, causing the neural firing rate to match the binaural beat, and this results in the brain functioning at the rate of the binaural beat.


The brain states: Delta 1-3Hz; Theta 4-8Hz; Alpha 9-14Hz; Beta 15-30Hz

The 8Hz frequency is your brain’s a natural dream state and will encourage relaxation and creativity.


Binaural beats have become misunderstood due to misrepresentation and incorrect production, to the point where Apple and Google saw fit to denounce binaural beats as a “gimmick” in their recent joint venture Digipil, despite claiming W.H. Dove’s work as the scientific basis for their sound hypnosis tracks. The fulcrum of the issue is that binaural beats can cause the frequency-following response in the brain. They might and they might not – if the conditions are right, they do; and if the conditions are wrong, they do not. In this way, binaural beats are not considered to be a form of sympathetic resonance, but occur on a more subtle level, where personal choice can change the outcome.

To create the right conditions, the person must have a good reason to follow the frequency, and the frequency must be a pleasant one to follow! For this reason, I offer psychoacoustic (sound hypnosis) sessions that use the 432 Hz chakra frequencies. Before going into hypnosis we discuss the reason for treatment and the best solution for you, and this will provide ample reason to follow the sound and allow the feeling of relaxation to occur. After all: hypnosis can occur, only if one allows it. In addition to using the exact frequencies of the chakras in ascending or descending sequence (I have produced one soundtrack of each) I have also layered binaural beats and isochronic pulses into the soundtracks, which are set to activate the Alpha state that corresponds to each chakra, so that each shift in frequency explores a slightly different level of Alpha, the dream state. The soundtrack is played during your hypnosis session through speakers in the reclining chair at a comfortable volume that allows you to hear my voice, so that I can assist you in rehearsing your solution and becoming familiar with it. (The binaural beats become effective in your personal hypnosis soundtrack which you will use at home, with earphones.)

Everything in life is vibration - Einstein


If we struggle to accept that “everything in life is vibration”, that is because our education system teaches historical science, not modern science. However, think of the human body as an aspect of “everything”, and how the body is effected by vibration. There is nothing “new age” about this: consider the most annoying sounds you can think of: hammer drill, toddler tantrum, car alarm – these are extremely irritating – why? They are nothing but vibrations! What about the most beautiful music that you can imagine – there may even be no words in that music, it has no literal meaning for you, but it has an extremely positive emotional and physical effect – beautiful sounds are very relaxing. Why? Because our bodies are extremely sensitive to vibrations. Sound is perceived by two of the body’s five senses – hearing, and touch. Not only the ear, but also the nervous system perceives sound, mostly unconsciously, but low frequency bass is very noticeable in the sternum or stomach. This means that the body is vibrating to every sound that we hear, albeit at a level below our perception.

“Progress” is a two-edged sword, and one of the most rewarding aspects of my work is knowing how lost we have become in the last 200 years and looking back into the golden ages for inspiration, and then using the amazing technology that I love about the last 200 years, to reproduce these ancient methods of healing – but the best part of my work is getting to test all of it on myself! I use my own personal hypnosis soundtrack every day, and sometimes I even sleep with it on, and it just keeps me relaxed, focussed, motivated, and ready for anything!
