Heinrich Wilhelm Dove was a physicist and a meteorologist in Liegnitz in the Kingdom of Prussia – a defunct German Kingdom that existed from the 18th century to the 20th century and occupied territory in many of present-day countries – who was born in 1803.
In 1839, he is credited for discovering binaural beats; a technique in which, when two slightly different frequencies are played in each ear, a perception of interference beats is produced at the same rate as would be created physically.
For binaural beats to work, stereo headphones or earphones must be used.
This is to enable the two frequencies to be delivered together without interfering outside the ear.
If they did, as would happen with loud speakers, it would then become monaural beats.
Brain entrainment is altering your brain waves and stimulating the brain into entering specific moods; mostly of relaxation.
Although binaural beats use sound, other entrainment techniques may use light or electromagnetic waves.
Besides binaural beats, other entrainment methods include:
• Monaural beats – Just like binaural beats, they involve two tones with the same intensity.
These tones are however mixed at source and the single tone resulting from it is made to pulse on and off in desired patterns.
• Isochronic tones – They have a pulsating tone that is achieved from turning on and off.
They employ a distinct and clean wave form that efficiently harmonizes with the brain.
They are often used with monaural and binaural beats. Isochronic tones are considered the most effective of sound entrainment.
• Sound and light Entrainment – As the name suggests, this is an audio-visual form of entrainment.
The light strobes in time with the beats which makes this a very powerful method. Its effects kick in almost immediately.
• Electromagnetic Entrainment – This method uses small, pulsing electromagnetic waves and is extremely fast-acting.
In 1973, Dr. Gerald Oster researched and presented a paper in the Scientific American. The paper was titled “Auditory Beats in the Brain”.
In the paper, he discussed how the brain interprets frequency signals to produce binaural effect.
This paper led to more research in the field of brain entrainment to what we have today.
Using binaural beats for lucid dreaming
Lucid dreaming involves having a dream and being aware at the same time. This means that you are aware of the fact that you are having a dream.
Brainwaves are known to have specific frequencies such as the gamma, beta, alpha, theta and delta waves.
Binaural beats can be set to work on any of those frequencies but the best frequency for lucid dreaming is the theta frequency.
This is between the 4Hz and 8Hz range.
To achieve lucid dreams using binaural beats, follow the following steps:
1) Since this works differently for different people, it is advisable to have a paper to note down what works for you. This is to have an easier time if you decide to try again.
2) You need to successfully perform either the Wake Initiated Lucid Dreams (WILD) or the Wake Back To Bed Method (WBTB).
3) Get sleep first. Ideally around 6 hours and then wake up as this is where you are most likely to experience lucid dreams.
4) Relax and play your chosen binaural beats. Remember to use stereo headphones.
