Receptive Sound Therapy uses auditory stimuli to help make positive changes in a persons mood, attitude, and actions. By positively influencing thoughts and feelings, it aims to improve their general life quality. As opposed to psychological stimulus, which uses a sound or a piece of music that has an existing association to a place, person, thought or experience to trigger a memory-based reaction, a neurological response is initiated by the properties of a sound itself and not by any pre–existing associations.

One way to achieve a neurological response is via Brainwave Entrainment, which involves synchronising brainwaves to an external stimulus. There are a number of techniques that can do this, but let’s examine one called “Binaural Beats”. It is an effective tool for influencing both cognitive and physiological processes – such as memory, creativity or pain management. Binaural Beats can speed-up or slow-down brainwaves to influence everything from relaxation, sleep, focus, and general well-being. In neurophysiology, the effect of Binaural Beats has been examined extensively and the influence they can have on our brains has been thoroughly documented.

How Do Binaural Beats Work?

Binaural Beats are responsible for a psychoacoustic phenomenon that occurs in the brain when the right and left ears are exposed to sine waves at a constant amplitude with a slight difference in frequency for each ear. For example, if a sine wave at 430 Hz is played in the left ear, and at the same time a sine wave at 440 Hz is played to the right ear (preferably over headphones), then the listener will perceive a pulsating tone of 10 Hz. The pulse produced in the head corresponds to the difference between the two frequencies.

Neurophysiological Research

There have been studies that have investigated the effect of Binaural Beats on the human organism – both on cognitive processes, e.g. creativity, memory, and physical aspects, such as pain. In the following page, we will take a look at some of this neurophysiological research.

Memory Performance

A study by Prof. T. Ortis investigated the effect of Binaural Beats on memory performance. As part of the experiment, twenty subjects were asked to remember incoherent words and then recite them back from memory. During the study, which was conducted over a 15-day period, they were stimulated with various acoustic signals: Binaural Beats of 5Hz and 13Hz and white noise, respectively. The results showed a significant positive effect as for those exposed twice a day to 15 minutes of 5Hz Binaural Beats.

Boost Creativity

At Leiden University in the Netherlands, an experiment explored the connection between Binaural Beats and creativity. In the study, 24 subjects performed 3 experiments per day: In the first, they were stimulated with a Binaural Beat using an Alpha frequency of 10 Hz, in the second with a Binaural Beat using a Gamma frequency of 40 Hz and in the third with a non-binaural, constant tone of 340Hz as a control situation.

The order of the three experiments was varied from participant to participant. At the beginning of the experiment, the participants were stimulated with one of the three sound sources, and then, while the audio signal was on, given various tasks requiring creative thinking.

In one part of the experiment, divergent thinking was examined. Tasks were set, e.g. to enumerate as many uses of a household item as possible in a given period of time. The second part of the task involved the study of convergent thinking. Participants were given the task of finding a word that can be linked to the three others, such as combining“super” with ’market’, ‘star’ and ‘hero’. The study found that stimulation with Binaural Beats, regardless of frequency, positively affects divergent thinking. On the other hand, the third non-binaural sound had no effect whatsoever on convergent thinking.

Reduce Anxiety

The prospect of surgery often leaves patients with a sense of anxiety. This can be explained by the feared loss of control, the unfamiliar environment, and the perceived risk of the procedure. Dr. Padmanabhan and his colleagues investigated the influence of Binaural Beats on the feelings of anxiety experienced before an upcoming operation. The study was conducted at the Sunderland Royal Hospital over a 6-month period with a total of 108 patients who were awaiting surgery under general anaesthesia.
About 45-60 minutes before surgery, participants were asked to complete a questionnaire to help them understand their subjective anxiety. Thereafter, each participant had one of the following randomly-triggered actions:

 

  • A Binaural Beat embedded in a soundtrack was played to them
  • A soundtrack without a Binaural Beat was played to them, or
  • No audio file was played to them (the Participants were allowed to read or watch TV, for example).

Participants were then asked to complete the same questionnaire again. The result was a significant reduction in the level of anxiety for those who had listened to Binaural Beats.

Reduce Pain

A study by Dr. Donna D. Zampi investigated whether Binaural Beats can be used effectively to relieve chronic pain. To this end, 36 patients who were suffering from various types of chronic pain were divided into two groups. One group listened to Binaural Beats at 6Hz for 20 minutes on 14 consecutive days, while the other group listened to a non-binaural tone of 300Hz as placebo. Subsequently, the groups were changed for the next 14 days. As a result, it could be proven that the perceived pain could be significantly lowered by listening to Binaural Beats.

Can Binaural Beats be Measured?

A number of studies have proven that listening to Binaural Beats can influence brainwaves and that the brain will synchronize to the frequency given by the Binaural Beats. This can be measured when a large number of neurons in the brain, send small electro-chemical signals to each other. This activity can be detected and visualized on an electroencephalogram (EEG). The voltage fluctuations on the surface of the head are measured and show the electrical activity of the brain as brainwaves.

Conclusion

It is safe to say, it is scientifically proven that Binaural Beats can positively influence various cognitive and physical processes, such as memory, creativity, fear or pain. Many listeners perceive Binaural Beats to be more pleasant when they are embedded in music as opposed to listening to pure sine waves.

SonicTonic provides both options.

Brainwave entrainment is a good example of technology positively affecting biology to intentionally synchronize our brainwave frequencies with an external stimulus. In our case, this stimulus is sound. We use Brainwave Entrainment to align thought patterns for different purposes. For example, to improve sleep, feel less stressed and calm or be more focused. There are various technologies available such as Binaural Beats or Isochronic Tones, that are each described in detail in the Knowledge Pyramid on www.sonictonic.io. This article will tell you about the different types of brainwaves and what they do.

 

What is Brainwave Entrainment?

Brainwave entrainment is the synchronization of the two hemispheres in the brain. Therefore, brainwave entrainment is also referred to as hemispheric synchronization. Using technical methods, it is possible to influence and reconcile the brain waves. Sound waves for instance are nothing more than vibrations of air. These little waves pulsate in a certain rhythmical pattern, that is being adopted by the brain waves. Like stomping your foot to a beat that is being played.
If you are very tense and need to concentrate, your brain will work in the gamma frequency range at 40 Hz (40 cycles per second). The dreamless deep sleep phase takes place in the delta frequency band – your brain waves then oscillate between 0.1 and 4 Hz.
By specifically influencing the brainwaves, you can control the individual activities in the brain itself. These states can be initiated entirely without the aid of technical means. For example, if you want to relax, or go to bed: if you live well, you will come to sleep without any aids.

 

How does Brainwave technology work?

Stimulation of the brain waves causes certain states of consciousness. The brain is consciously directed to the appropriate work mode in which it works best.
It can be proven that brain waves can be influenced if you provide the brain with opportunities that it understands. Since the brain waves move in the frequency range between 0.1 and 40 Hz, it just needs these frequency bands to address the brain directly. Problem: Human hearing perceives sounds that range from 20 Hz to 20,000 Hz. Outside this frequency range we cannot hear any frequencies. Brainwave technology, however, knows ways to circumvent this.

 

Firstly, it is important to know that humans display five different types of electrical patterns or “brainwaves” across the cortex. All brainwave entrainment increases the growth of new neural pathways, and improves the communication between the right and left hemispheres.

From high to low frequency, the brainwaves are:

Gamma 31 Hz -100 Hz, Beta 14 Hz -30 Hz, Alpha 9 Hz-13 Hz, Theta 4 Hz -8 Hz, and Delta 0 Hz – 4 Hz. The brainwaves can be observed with an EEG (“electroencephalograph”) – a tool that makes brainwave patterns visible.

Each brainwave has a specific purpose and allows for optimal mental functioning. Our brain’s ability to become flexible and to transition through the various brainwave frequencies plays a large role in how successful we are at managing stress, focusing on tasks, or getting a good night’s sleep.

If one of the five types of brainwaves is either overproduced or under produced in our brain, it can cause us problems. For this reason, it is important to understand that there is no single brainwave that is “better” or more “optimal” than the other. They all have their purpose at different times. By exposing ourselves to specific frequencies, we can influence the way we think and feel. Let’s take a look at the individual frequencies.

 

____________________________________________________

 

  • Delta Waves |(0 Hz to 4 Hz) (Slowest)

 

These are the slowest recorded brain waves in human beings. They are found most often in infants as well as young children. As we age, we tend to produce less delta even during deep sleep. They are associated with the deepest levels of relaxation and restorative, healing sleep. They have also been found to be involved in unconscious bodily functions such as regulating heart beat and digestion. Adequate production of delta waves helps us feel completely rejuvenated after we wake up from a good night’s sleep. If there is abnormal delta activity, an individual may experience learning disabilities or have difficulties maintaining conscious awareness (such as in cases of brain injuries).

 

Lack of Delta Waves can cause: Inability to rejuvenate body, inability to revitalise the brain, poor sleep

 

____________________________________________________

 

  • Theta Waves |4 Hz to 8 Hz (Slow)

 

Theta is the best state for memorisation and creativity. In the Theta state the brain activity has slowed below Alpha (at approximately 4-8 Hz) and an even greater connection occurs between the conscious and unconscious mind. It is here that intuition and spontaneity happen, and creative problem solving can be well-utilized. The Theta state is often suspected to be the resource of great artists and thinkers. If you need to memorise a lot of information – history, formulas, etc., Theta may be your best bet. Theta waves are connected to us experiencing and feeling deep and raw emotions. Too much theta activity may make people prone to bouts of depression and may make them “highly suggestible” based on the fact that they are in a deeply relaxed, semi-hypnotic state. Theta waves can help us to improve our intuition, creativity, and makes us feel more natural. They are also involved in restorative sleep and daydreaming. As long as Theta isn’t produced in excess during our waking hours, it is a very helpful brain wave range.

 

Lack of Theta Waves can cause: Anxiety, poor emotional awareness, stress

 

____________________________________________________

 

  • Alpha | 9 Hz to 13 Hz (Moderate)

 

The Alpha state occurs when brain activity slows just below the normal waking state of Beta (14-30 Hz). In Alpha, the mind and body are relaxed but a level of focus is easily maintained. Modern brain science has shown that only 1 of 6 of our brain’s processing methods happen on the conscious level, so there is certainly a benefit in engaging the deeper parts of the brain, while taking in information. This frequency range bridges the gap between our conscious thinking and subconscious mind. In other words, alpha is the frequency range between beta and theta. It helps us calm down when necessary and promotes feelings of deep relaxation. If we become stressed, a phenomenon called “alpha blocking” may occur which involves excessive beta activity and very little alpha. Essentially the beta waves “block” out the production of alpha because we become too aroused. There is also a greater link between the conscious and subconscious mind in Alpha, meaning that while one is consciously learning, their brain is also unconsciously processing what one is learning.

 

Lack of Alpha Waves can cause: Anxiety, high stress, insomnia, OCD

 

____________________________________________________

 

  • Beta 14 Hz to 30 Hz (High)

 

These are known as high frequency low amplitude brain waves that are commonly observed while we are awake. They are involved in conscious thought, logical thinking, and tend to have a stimulating affect. Having the right amount of beta waves allows us to focus and complete school or work-based tasks easily. Having too much beta may lead to us experiencing excessive stress and/or anxiety. The higher beta frequencies are associated with high levels of arousal. When you drink caffeine or have another stimulant, your beta activity will naturally increase. Think of these as being very fast brain waves that most people exhibit throughout the day in order to complete conscious tasks such as: critical thinking, writing, reading, and socialization.

 

Lack of Beta Waves can cause: ADHD, daydreaming, depression, poor cognition

 

____________________________________________________

 

  • Gamma | 31 Hz to 100 Hz (Highest)

 

There is also great value in producing Gamma waves, as these, more than the other brainwaves, have been directly linked to increased IQ, enhanced cognitive function, and improved memory. If you need to learn something new, I would recommend Alpha, as the relaxed yet focused mental state will make it much easier to stay interested and process clearly. It also wouldn’t’t be a bad idea to listen to some Gamma brainwave entrainment audios on a semi-regular basis when one is not actually studying to help boost IQ and cognitive functioning. Gamma waves are involved in higher processing tasks as well as cognitive functioning. Gamma waves are important for learning, memory and information processing. It is thought that the 40 Hz gamma wave is important for the binding of our senses in regards to perception and are involved in learning new material. It has been found that individuals who are mentally challenged and have learning disabilities tend to have lower gamma activity than average.

 

Lack of Gamma Waves can cause: ADHD, depression, learning disabilities

 

 

 

 

 

 

 

Autosuggestion trains the subconscious mind to influence the way a person thinks, perceives and believes. As well as implementing the power of positive thinking, it builds on such techniques as Progressive Muscle Relaxation, Autogenic Training, Active Imagination and other tried and tested psychological methods.

Emile Coué (1857-1926) was a French pharmacist and pioneer of autosuggestion. Coué who, after reading the writings on hypnosis from the “School of Nancy” (A. Liébeaut and H. Bernheim), developed a very simple method of self-hypnosis. Every day before falling asleep and after waking up, the patient should repeat 20-30 times the now famous sentence: “Every day, in every way, I’m getting better and better.

Autosuggestion uses positive affirmations to replace negative thoughts, opinions or beliefs with good and healthy ones. For this technique to properly take effect, the recipient must first achieve an altered state of consciousness. The reason for this is that, when we are in our normal waking state, the new thoughts or ideas have to get past our critical minds, which isn’t that easy. When the idea that we want to suggest, contradicts a belief or opinion that we have previously held to be true, we immediately activate and reinforce the original thought we wanted to avoid, which is not going to give us the effect we want.

Under The Radar

“Unconscious” is the keyword; Positive affirmations, such as Coué’s aforementioned line, enter our minds under the radar. They by-pass our critical mind and create new beliefs.  It is the same thing when we are dealing with stress: in the waking state of consciousness, we tell ourselves to relax and it just doesn’t work. The more we will ourselves to relax, the more we just get tense. But when we hear new ideas or suggestions, communicated in a slow, monotonous voice, or embedded in relaxing music, they are more inclined reach our subconscious mind, and our critical minds will be distracted. The words influence us, and the effect is that we relax.

The reason that the Coué method of autosuggestion is so effective in making positive mental changes, is because it does not involve willpower. Attempting to use willpower inevitably leads to the strengthening of exactly those existing ideas, that we want to avoid.

So whether you want to reduce stress, relax or change some unwanted or disturbing mental patterns, autosuggestion will help you to switch off your critical minds in order to achieve the mental state you desire.  For best results, you should make it a habit and integrate the program into your daily routine!
