Molecular Frequency of H₂O Water

The Molecule of Life - Application in Vibrational Sound Therapy

---

Water makes up 70% of our body, which is about 50 liters in an adult.
At Naturasounds, we have calculated its molecular resonance frequency at 107.40 Hz, based on its molar mass (18.015268 g/mol) and the Einstein-Planck equation (E = hf = mc²).
This frequency is the foundation of our therapeutic tuning forks dedicated to water.

How is the frequency of H2O water calculated?

The formula used is based on the simplified Einstein-Planck equation:

Molecular mass × 2.98095104304559 = Frequency (in THz)

For water (H2O, molecular mass 18.015268 Da):

• 18.015268 × 2.98095104304559 = 53.716 THz
• After transposing 72 octaves into the audible range: 107.40 Hz (precisely 107.398746 Hz)

This frequency of 107.40 Hz is what we call the fundamental frequency of water.

The harmonic series of water: from 26.85 Hz to 1718.48 Hz

Starting from this fundamental, water possesses a complete harmonic series:

429.62 Hz and 432 Hz: what is the difference?

These are two different frequencies, often confused:

• 432 Hz: historical tuning, sometimes called the "frequency of nature," used by some composers and musicians since the Baroque era.
• 429.62 Hz: the second octave of our calculated water frequency (107.40 Hz), obtained mathematically from its molecular mass.

The gap between the two is only 2.38 Hz (approximately -9 cents) — imperceptible to the ear, but significant in our precision calculations.

In practice:

• For sound therapy targeting bodily water: we recommend 107.40 Hz or 429.62 Hz.
• For music: 432 Hz remains an excellent choice, widely documented and used. Renaud Ruhlmann discusses it in his work, as he has written several articles and conducted research since 2016 on the subject of 432 Hz. Hence this refined frequency of 429.62 Hz, which he was able to produce in collaboration with Prof. Marc Henry in late 2019.

What does science say about frequencies and water?

What is scientifically established:

• The frequency calculation using the Einstein-Planck equation is mathematically correct.
• Mechanical vibrations have a demonstrated effect on tissues (a principle used in vibrational physical therapy).
• The human body's water composition (approximately 70%) is an established physiological fact.
• Near-infrared spectroscopy studies have shown that certain sound frequencies (432 Hz, 440 Hz) can temporarily modify the molecular organization of water.

What remains debated or unvalidated:

• The theory of "water memory" or "structured water" is a subject of scientific debate: some chemists point out that water's molecular structures reorganize in a few picoseconds.
• The effects felt when using a tuning fork (relaxation, sense of well-being) have not been subject to double-blind clinical trials to date.

We prefer to present this approach as a complementary practice for well-being and relaxation, to be explored in addition to — never as a replacement for — appropriate medical follow-up.

How to use the H2O tuning fork?

Simple use for relaxation:

1. Activate the tuning fork by striking it gently against a soft surface.
2. Bring it near your ear or place it gently on your sternum or hands.
3. Let the vibration continue until it fades naturally (15-20 seconds).
4. Repeat during a 10 to 15-minute session, in a setting of relaxation or meditation.

Suggested frequency of use: 2 to 3 times per week, depending on how you feel.

Frequently Asked Questions

Is the H2O tuning fork a medical device? No. It is a tool for well-being and relaxation. It does not replace medical advice or treatment.

What is the difference between the 107.40 Hz and 432 Hz tuning forks? The 107.40 Hz is calculated mathematically from the molecular mass of water. The 432 Hz is a historical musical tuning fork. Both belong to related vibratory families.

Can the H2O tuning fork be used in music? It is designed for therapeutic and relaxation use rather than musical tuning, but there is nothing to stop you from exploring it for creative purposes.

In summary

The 107.40 Hz H2O tuning fork is based on a rigorous calculation derived from the molecular mass of water via the Einstein-Planck equation. It is a sound therapy and well-being tool, to be integrated as a complementary practice into a relaxation routine — with transparency regarding what science confirms and what remains, to this day, clinically unproven.
