The purpose of Brainwave Entrainment is tuning the brain to frequencies (beta, alpha, theta, delta, gamma) that are associated with certain states of consciousness. Think of different mental activities such as
- 'to sleep’,
- 'concentration and focus’,
- 'unwind' and
- in 'meditative state of consciousness'.
Our brains are an incredibly complex network of neural processes and the activities in our brains can be measured as brain waves. By measuring the brain waves, we see that the brain constantly adapts to what our senses perceive and how we process that information. The brain waves tell us in what state of mind someone is and the mental activities that go with it.
Meditate better with Brainwave Entrainment
What you see here is a measurement of a number of minutes where the red line is especially noticeable; Delta - the thinking. Slightly restless in the beginning. Then the occasional peak where you see more space between Delta and Alpha and at the end everything is restless again. The peaks are moments when I opened my eyes for a moment and looked at the measurement.
Synchronize the brain waves
Because our brains continuously adapt to the most dominant signals they receive through the senses, they can also be stimulated. Through the conscious use of 'binaural' and 'monaural' rhythm and isochronical tones, or Brainwave Entrainment, we can control the brainwaves, as it were. The synchronization of both hemispheres of the brain - Hemispheric Synchronization - is a desired end result from Brainwave Entrainment. It is a state of consciousness in which both hemispheres show the same patterns and activity. It is often said that people with better synchronization are happier, emotionally stable and less susceptible to mental illness. This is especially seen in people who regularly meditate and say they are happy with their lives.
The frequency bands of the brain waves
A distinction is made between different bandwidths of consciousness and their associated frequencies. We speak of frequencies about Hertz, which corresponds to 1 wave or vibration per second.
Beta - 12 to 30Hz
The brain waves in the Beta bandwidth belong to our normal waking consciousness. These are associated alertness, logical thinking, problem solving, concentration and other active mental activities. You are also in this state of consciousness during sports and in conversation with other people.
The higher levels of Beta can be the result of stress, excitement or restlessness. Even though you have to be in a Beta consciousness to perform your normal daily activities, many people are in the higher stress related frequencies.
Alpha - 7 to 12 Hz
The Alpha brain waves are slower in frequency compared to Beta and therefore naturally provide a more relaxed consciousness. The state of consciousness is common in people who are naturally calm and relaxed. It is as if you are daydreaming or when you close your eyes to meditate. This frequency promotes imagination, memory, concentration, creativity and reduces stress, which benefits learning.
Meditation causes an increase in Alpha frequencies in the brain and the ability to retain this in everyday things. In children, more Alpha is generally seen than in adults.
Theta - 4 to 7Hz
Theta brain waves are reflected in deep relaxation and meditation, light sleep and / or the brake sleep where you dream. It is also where the subconscious mind is active and you are able to come to deep insights and intuition. It is in this consciousness that we come to higher universal insights that can change our lives.
It sounds contradictory, but the lower the brain waves, the easier one learns. Theta is the consciousness where visualisations, inspiration and creativity are powerful. Meditation and yoga is often praised as beneficial because it generates these theta frequencies in the brain. Many people also get paranormal experiences due to a higher sensitivity during theta.
Delta - 0.5 to 4Hz
Brainwaves in the bandwidth of Delta have the highest amplitude and are observed in deep sleep. These frequencies form an opening to mystical experiences and the collective subconscious. Of course we all know the healing effect that comes from a good night's sleep, which is associated with these frequencies.
Experienced yogis who are able to get into deep meditation can be able to come into contact with their subconscious. This is attributed to things like self-healing, higher insights and wisdom about many aspects of life and our existence.
