How can the RELAX and SLEEP Tones be beneficial if they are below the range of human hearing?

What human beings perceive as sounds are actually mechanical vibrations that can travel through liquids, solids or the air. Vibrations within the range of 20 and 20,000 cycles per second (Hertz) physically resonate the human ear drum and are interpreted by the brain as sounds or tones. While sound waves below 20 Hertz are no longer perceptible by the average person, they still exist and continue to pass through the area.

Electroencephalography - the recording of electrical activity along the scalp produced by the firing of neurons within the brain - has revealed the frequency ranges associated with different states of brain activity as follows:

Frequency Range
40 Hz and higher
Focus & Perception
13 Hz to 40 Hz
Alert & Active
7 Hz to 13 Hz
Wakeful Relaxation
4 Hz to 7 Hz
Dreaming & Meditation
4 Hz and below
Deep Dreamless Sleep

Just as musical tuning forks resonate spontaneously when exposed to harmonic frequencies, the human body senses and resonates in response to the waveforms produced by the RELAX and SLEEP Mood Tone Generators.

  • At 4.0 cycles per second, the SLEEP Tone encourages the listener to float in a natural state between dreaming (Theta) and deep, dreamless sleep (Delta).
  • At 7.83 cycles per second, the RELAX Tone is found at the quiet end of wakeful relaxation (Alpha).

As such, the BETAR Tones may be perceived as a soothing hum or not at all. But the body and brain will recognize these tones and, through the principle of entrainment, seek to find a state of resonance with the external tone. In this way, the brain may pleasantly and easily fall into rhythm with the BETAR Tone, producing a comfortable shift in mood and brain activity state in the process.

How are the BETAR Mood Tones generated and emitted without a speaker?

The BETAR Mood-O-Matic Mood Tones are generated electronically using solid state technology. These electronic signals are then delivered to BETAR USA's exclusive dual-spin coil antenna - our version of the bifilar coil first patented by the father of modern electricity - Nikola Tesla - in 1894. The result is a low frequency wave that will not interfere with normal conversations or activities.

What is the effective range of a Mood Tone Generator?

  • Mini Mood-O-Matic: 10 feet (3 meters)
  • Micro Mood-O-Matic 3 feet (1 meter)

However, because the signal fades as the distance between the device and the user increases, keep the unit close by for maximum benefit.

What is Schumann Earth Resonance and the Earth Tone?

Just as musical tuning forks resonate when exposed to harmonic frequencies, the naturally-occurring electromagnetic and atmospheric activity of our planet resonates in harmony with a family of frequencies that are defined by the distance between the Earth’s surface and the ionosphere - the conducting plasma layer of the atmosphere that stretches from 40 miles to 950 miles above the ground. These Earth resonance frequencies range from 7.83 to 59.9 cycles per second (hertz).

The were first documented observations of global electromagnetic resonance were recorded by Nikola Tesla in 1899. They were first predicted mathematically by the German physicist W. O. Schumann in 1952, then located experimentally by Professor Schumann and a colleague in 1954. For his contribution, the Earth Resonances were named for Professor Schumann.

The Earth Resonance Frequencies have been present throughout the history of the world. It should be no surprise that this planetary hum would have a special relationship with the life forms that live upon it.

Do BETAR Mood-O-Matic Mood Tone Generators block unwanted frequencies, signals or "electro-smog"?

Modern life subjects us to constant bombardment by high energy frequencies that can impact our personal energy and affect our brainwave states. Just as brainwave entrainment can allow the brain to migrate toward a relaxing tone, the human brain can also migrate toward high energy tones that can produce a state of over-stimulation. For example, fluorescent lighting flickers on and off at the rate of 60 cycles per second in the United States - twice the speed of a projector in a movie theater. People who work under high intensity lighting often have a difficult time relaxing at the end of the work day.

The BETAR Mood-O-Matic Mood Tone Generators cannot block these external frequencies, however they can provide the dominant stimulus needed to allow the brain to remain centered in a positive state of relaxation or to remain asleep. This is analogous to the person who plays soothing classical music in his or her home in order to drown out the noise coming from the busy street outside. The noise outside is still present, but the listener is focused on the relaxing music being played inside the house.

Can BETAR USA provide the correct power supply for my country?

We are extremely proud to have shipped BETAR Mood-O-Matic Mood Tone Generators to every part of the world, including Italy, Japan, Russia and Australia, and many other nations. Each Mood-O-Matic is supplied with a switching power supply that will detect and adapt to electrical power between 100-240 volts AC, at 50 or 60 Hz. However, the plug on this power supply will only work with North American wall sockets. International clients will have to locate and utilize the correct socket/plug adapter.

Alternatively, some global customers may wish to consider purchasing the appropriate power supplies locally, where this common configuration should be readily available in any electronics store or online:

  • 9 volts of direct current (DC) power at 500 milliamps
  • inside-positive tip
  • 5.5 mm external sleeve
  • 2.1 mm internal sleeve
3.5 mm "Atari" tip plug 3.5 mm "Atari" tip plug

Any international customer who wishes to purchase the correct power supply in their home country will have the option of receiving a $10.00 credit against the price of each Mood-O-Matic device purchased.

What is the expected battery life for the Micro Mood-O-Matic?

A new battery should provide 60 to 90 hours of continuous use. We recommend the use of rechargable batteries.
