The Positive Impact of Sound on the Body

What we consider “sound” is actually vibrations in the air or other mediums such as water. These vibrations create waves which are then perceived by our auditory receptors and various mechanoreceptors in the skin. These receptors carry information to the brain through electrical signals, which can have numerous effects on the brain and body. This article will focus on the positive impact of sound on the body.

Important Frequencies

With the help of electroencephalography (EEG), which was developed by Hans Berger in the early 1900s, we were able to discover that the brain has its own frequencies as well. In fact, there are five different kinds of waves that the brain emits during different stages of consciousness, focus, and relaxation:

Gamma: >40 Hz. Present during times of unusually high-level information processing and while gaining insight.
Beta: 14-40 Hz. Present during times of moderately sustained focus and while using reasoning abilities and logic.
Alpha: 7.5-14 Hz. Present when you are relaxed and your mind can rest/wander.
Theta: 4-7.5 Hz. Present during light meditation, REM sleep (dreams), and very deep relaxation.
Delta: 0.5-4 Hz. Present during deep, dreamless sleep and in very deep and sustained meditation.

The human body also has its own frequency. Several studies show that the body’s average resonant frequency is right around 10 Hz, with some research showing that it may be closer to 12 Hz.

Thanks to the thousands of lightning storms that rage around the planet at all times, the Earth has a “repeating atmospheric heartbeat,” known as the Schumann Resonance. This is an extremely low-frequency wave (ELF) that remains around 10 Hz and can go as low as ~8 Hz.

An Overview of Frequency

Sound waves with different frequencies (measured in Hz) emit different pitches. This characteristic of the wave helps us differentiate between different sounds. Higher frequency waves translate into higher-pitched sounds, and lower frequency waves translate into lower-pitched sounds.

As stated by The Physics Classroom, “all objects have a natural frequency or set off frequencies at which they vibrate.” This extends to all matter, as everything in the universe is constantly vibrating, and each object’s unique properties determine its range of frequencies. This principle applies to people as well. For example, one study found that the standing human body’s resonant frequency (natural frequency) is between 9 and 16 Hz.

For reference, the Earth’s resonant frequency, also called the Schumann resonance, is about 8 Hz, and the frequency of the brain when relaxed, meditative, or daydreaming (Alpha waves) is around 8 to 13 Hz. Theta brainwaves, associated with deep meditation, internal awareness, and the time between sleep and wakefulness, are 4 to 8 Hz.

Why Does Frequency Matter?

There is evidence that interference from electromagnetic fields may have several adverse effects on our health and well-being.

This includes both natural electromagnetic fields, which have been proven through studying circadian rhythms to affect human beings, as well as artificially made electromagnetic fields produced by the electric grid, technology, telecommunication, etc.

This is especially true for people that work closely with electromagnetic radiation for a long period of time. Long-term exposure may cause psychological changes, genetic effects, and reduced immune function.

The Earth, the human body, and the relaxed brain all display very similar frequencies一at least they’re supposed to. This is why it’s important to bring the mind and the body back to ~10 Hz as often as possible. Realigning yourself and harmonizing your body and brain with the resonant frequency of the Earth can help you stay healthy both mentally and physically.

Using Meditation To Achieve Harmony

The good news is that the brain often cannot tell the difference between reality, visualization, and dreams. This is why you might blush or notice an elevated heart rate when you remember (or imagine) an embarrassing or shameful moment, and why you can wake up from a dream laughing or crying as if you had truly experienced the events created by your sleeping mind.

This is what makes meditation and visualization such powerful tools. Meditation, mindfulness, breathing exercises, and visualization can lead to brainwaves of a lower frequency, which helps us realign ourselves with both our bodies and the Earth. This is a great way to battle stress, calm the body and the brain, and bring yourself back into harmony.

Getting Started With Meditation

There are many different ways to meditate, and there are some easy tips and tricks that you can put into practice today to help improve your experience, such as breathwork and brain training.

The goal is to quiet the mind, bring yourself back to the present moment, and intentionally alter the state of your brainwaves. This can provide a break from the stressors of daily life and help you gain more control over your own mind. In terms of aligning frequencies, consistent meditation practice may also help you maintain good health and well-being in the long run.

Tech-assisted meditation can also be beneficial to people who wish to enhance their meditation practice. Vibroacoustic therapy mixes vibration and sound and is based on the above principles about how different frequencies have different effects on human health and wellness. InHarmony’s products use vibroacoustic technology to help you reach a deeper meditative state and stay in it for longer. This allows you to get the most you possibly can out of your meditation practice.

In Review

Everything in the universe is in constant movement and all matter has its own frequency. The various electromagnetic fields on Earth can have adverse effects on our physical and mental health, especially over time. Meditation, mindfulness, and visualization can help bring our brains and bodies back into alignment with the resonant frequency of the Earth.

The best way of doing this is by being consistent in your meditation and mindfulness practice and continuing to learn about how you can elevate your experience.

How Frequencies Affect Us

So, why does this matter? Frequencies have an effect on our bodies and our minds. Several studies have proven that external auditory stimuli such as music and tones can alter brainwaves, thus having a positive (or negative) effect on physical and mental health. Music has even been shown to have a physiological impact on the human body and can affect things such as heart rate, respiration, and blood pressure.

How Sound Impacts Us

For thousands of years, people have used sound as both a form of art and a form of medicine. For example, ancient Greeks and Egyptians used music as a therapeutic for helping the sick, and Hindu and Buddhist faiths have used tones and chants such as “Om”, or “Aum”, to deepen their meditation and expand their spirituality.

Since long before the physics of sound was understood or the physiological effects discovered, music was used to energize and inspire warriors and soldiers in battle, lull children to sleep, and everything in between.

Music therapy is used in the modern world to help with a wide range of psychological and chronic ailments, though this field is still being investigated.

A significant factor contributing to music’s positive effect on the body is the release of dopamine that occurs while listening. When you hear a song that you enjoy, the chemical dopamine is released, bringing feelings of pleasure and satisfaction. Dopamine also helps regulate a number of important systems such as digestion, sleep and the circadian rhythm, memory consolidation, motor function, mood and emotional regulation, and more.

Are Some Sounds “Better” Than Others?

There are claims by many casual music listeners, creators, and scientists that music created at the frequency of 432 Hz is beneficial for reducing stress and increasing focus and relaxation, among other benefits. This also happens to be the frequency at which “Om” vibrates when chanted.

Binaural beats are another example of frequencies at work. This form of sound therapy consists of two different tonal frequencies being played in each ear, causing the brain to perceive a third frequency.

For example, a tone being played at 410 Hz in the left ear and 420 Hz in the right ear will result in a binaural beat of 10 Hz. Proponents of this strategy claim that different binaural beats can help reduce stress, increase focus, and improve mediation and sleep, among other benefits. Studies into the effectiveness and possible clinical applications of this kind of sound therapy are ongoing.


In Review

Sound can be a profoundly helpful tool when it comes to improving relaxation and mood, and music may even have positive effects on physical health in some situations. Humans have used tones and music for millennia to heal physical and mental ailments, grow their spirituality, and celebrate the beauty of sound. It is proven that sounds and frequencies affect the brain, and many modern applications for music and vibrational therapy applications are still being researched.
