What are sound frequencies?

Sound Frequency refers to the number of oscillations of sound waves per second, measured in hertz (Hz).

Different frequencies of sound have different effects on the body, and can be used in sound frequency therapy to target specific areas of the body and stimulate the body's own healing mechanisms.

How it Affects the Body

  • Low-frequency sound waves may be used to help reduce inflammation, while higher-frequency sound waves may be used to help stimulate the body's natural production of endorphins, which can help to relieve pain.
  • Higher-frequency sound waves may be used to help stimulate the body's natural production of endorphins, which can help to relieve pain.

Sound Frequency Therapy

  • Sound frequency therapy is a form of holistic medicine that is used to promote healing and alleviate pain.
  • It is clinically and scientifically proven method of non-invasive support.

How It Works

Imagine that your body is like a big musical instrument, and each part of your body makes a different sound. Just like how a guitar has different strings that make different notes when you pluck them.

Now, when you listen to music, it's like someone is playing different notes on your body. Some notes make you feel happy, like when you hear your favorite song, and some notes make you feel calm like when you listen to lullabies. These are called "good notes" and "relaxing notes".

And just like how you can play different songs on a guitar, different frequencies can make different things happen in your body. Some frequencies can make you feel calm and happy, and some can make you feel awake and focused.

Sound therapy is like someone playing "good notes" or "relaxing notes" on your body to make you feel better. And if you're feeling sad or not feeling well, these "good notes" can make you feel better, just like how your favorite song makes you happy!

Scientific Studies

Vibroacoustic therapy (VAT) shows promise as a safe, noninvasive approach to relieve temporomandibular joint (TMJ) pain.

Low-frequency vibrations used in VAT may help reduce inflammation, improve circulation, and promote muscle relaxation, though larger clinical trials are still needed.

effects on the body

Synchronicity & Balance

The Principle of Entertainment states that when two systems that are oscillating at different frequencies are brought into close proximity, they will tend to synchronize their oscillations.

This can happen naturally in the body, as different systems such as the brain, heart, and breath tend to oscillate at different frequencies. When exposed to sound frequencies that match these natural oscillations, the body can become more synchronized and balanced.

Production of Serotonin & Dopamine

Another way that frequencies affect the body is through their ability to stimulate or inhibit the production of certain neurochemicals.

For example, exposure to low-frequency sound waves has been found to increase the production of serotonin, a neurochemical associated with feelings of well-being and happiness. Similarly, exposure to high-frequency sound waves has been found to increase the production of dopamine, a neurochemical associated with motivation and pleasure.

Relaxation & Stress Relief

Certain frequencies can also affect the body by vibrating it at specific frequencies.

Some frequencies, such as those in the alpha and theta ranges, have been found to stimulate healing. This is the case with some forms of sound therapy, such as Vibrational sound therapy or Gongs therapy, which promotes relaxation, reducing stress, and helping to clear blockages in the body's energy pathways.

Alertness & Concentration

Other frequencies, such as those in the beta range, can stimulate alertness and concentration.
