Sience

Any reasonable person would be sceptical of big claims and big promises.

Here at spryfuel® we inform you what is scientifically proven and what is not - but in the second case this does not necessarily mean that it does not work.

As new scientific discoveries are constantly being made in the field of neuroacoustics and biofrequencies, we are able to quickly update, improve and refine our methodology. Over the past 10 years, we have made hundreds of adjustments, improvements and updates to ensure our materials use the most accurate and up-to-date technology.

Maybe you've never heard of Brainwave Entrainment? But this scientific field is not new. In fact, it's been around for almost a century and has been proven in laboratories.

Interest in research with auditory stimuli continues to grow, opening the door to a better understanding of how to influence neural and physiological functions in the body. Below you will find a small selection of studies with clinical relevance:

spryfuel® frequency medicine is based on hundreds of studies that prove the effectiveness of brainwave entrainment technology. Here you will find a selection of the more than 100 scientific studies on which our methodology is based. If we were to add the studies for mindfulness and meditation, we would have at least 1000 more studies proving that mental training is an extremely effective tool.

We encourage you to do your own thorough analysis of this research and bring any inconsistencies, suggestions or questions to our attention.

Brain frequencies

Brain waves are generated by the electrical activity of the brain. They can be measured with an electroencephalogram (EEG). There are several recognised types of brainwaves. Each type is associated with a frequency range and a mental state. The five most common types are listed in order from highest to lowest frequency:

  • Gamma (32–100 Hz): High concentration, turbo learning, ranscendental thinking and problem-solving ability
  • Beta (15–20 Hz): Active mind, focus, clarity, energy or a normal waking state.
  • Alpha (8–13 Hz): Relaxation, calm and restful mind, light meditation, reflection
  • Theta (4–8 Hz): State of tiredness or daydreaming, meditation, trance, lucid dreaming
  • Delta (1–4 Hz): Deep sleep, dreaming, collective unconsciousness

Body frequencies

But we don't stop at brainwave frequencies and go one important step further. We offer a huge range of exclusive frequency programmes for the body, which can be applied by sound. Many of these target specific problems, pains and organs.

  • Lambda (100-200 Hz) – Hyper gamma range, mindfulness, holistic perception
  • Epsilon (0,1-0,5 Hz) – Mindfulness, holistic perception (correlates with lambda)
  • Solfeggio (175 Hz – 963 Hz) – Spirituality, Body & Mind Effects
  • Dr. Rife Frequenzen (0-10.000 Hz) – Physical Self-Regulation & Self-Healing
  • Dr. Clark Frequenzen  – Physical Self-Regulation & Self-Healing
  • Ontogenetische Frequenzen according to Nogier - organ-specific regulation
  • Planetare Frequenzen – Fundamental vibrations of the planets
  • Schumann Frequenz – Basic stability of the organism

Complex sound design with the latest technology

We use many different techniques to produce our auditory frequency medicine. We focus on the latest discoveries and scientific research, and combine classic, tried and tested techniques with the most promising new frequency and modulation techniques to create new and unique brain entrainment programmes that you can only get from us.

Binaural Beats Studies

15 Hz improve the cognitive network in mental exhaustion

The aim of this August 2022 study by Wang, Lu, He, Sun, Feng and Zhu was to investigate the effectiveness of binaural beats in combating mental fatigue. Subjects underwent a psychomotor vigilance task (PVT) and were assessed with a 3-min resting electroencephalogram (EEG). This was followed by a 20-minute mental fatigue task while one group listened to binaural beats at 15 Hz, another listened to binaural beats at 40 Hz, yet another listened to relaxation music, and the fourth group listened to a pure tone at 240 Hz. After the fatiguing task, the subjects were again assessed with different scales, a PVT task and a 3-minute resting EEG.

The results of this study show that listening to 15 Hz binaural beats is a proven intervention for mental fatigue that can help maintain working memory function, improve the topological structure of the brain and mitigate the decline in brain function that occurs with mental fatigue. Therefore, these results are of great scientific and practical value.


Stronger focus of attention

In 2017, a study by Barone, Colzato, Hommel and Sellaro demonstrated that binaural beats have an impact on attention span. A group of adults listened to binaural beats with the gamma frequency of 40 Hz for 3 minutes before and during a global-local task. Another control group was given a constant tone of 340 Hz to listen to.

The study showed that the group with the binaural beats in the gamma range of 40 Hz had a significantly faster reaction time because they reduced the focus of attention. The 40 Hz group needed a reaction time of 36ms for the task, while the control group needed 57ms.


Better memory

In a 2019 study, Trusted Source, led by Garcia-Argibay, Santed and Reales, investigated how binaural beats affect memory in 32 participants. Participants listened to binaural beats that were either in the beta or theta range, which are associated with an active mind and sleep or fatigue.

Afterwards, participants were asked to complete memory tasks. It was found that people exposed to beta binaural beats recalled more words correctly than those exposed to theta binaural beats.


Better deep sleep

In a 2018 study, Trusted Source, led by Jirakittayakorn and Wongsawat, investigated how low-frequency binaural beats affect sleep in 24 participants. The beats used were in the delta range associated with deep sleep.

It was found that the duration of deep sleep was longer in the participants who listened to binaural beats than in those who did not. In addition, these participants spent less time in light sleep than those who did not listen to the beats.


Increase creativity

In 2013, a study was made by Bolders and Hommel on creativity in connection with binaural beats. The subjects each heard one group of alpha frequencies of 10 Hz, another group of gamma frequencies of 40 Hz and a control group of 340 Hz. The subjects had to complete one divergent thinking task and one convergent thinking task to assess creativity. They were also given a PANAS-S mood questionnaire to complete. Since dopamine is associated with creativity, dopamine levels in the striatum were estimated using spontaneous eye blink rates (EBRs).

The results showed that binaural beats, regardless of frequency, can influence divergent thinking.


Increase capacity of working memory

A 2015 study investigated the effect of binaural beats on working memory capacity. A study was done in the alpha wave range, as it was assumed that brainwave activity in the alpha range is generally associated with many cognitive functions and the improvement of working memory. There were two groups for the study: One group listened to binaural beats with ocean noise and the other group listened to ocean noise only.

Working memory capacity was measured at the beginning and after listening to the binaural beats using the OSPAN method. The study proved that only the participants in the binaural beat group showed a significant improvement in working memory.

Further studies on binaural beats

Monaural Beats Studies

In a 2017 study, Trusted Source investigated the effect of monaural beats on anxiety and cognition in 25 participants. The beats were in the theta, alpha or gamma range. Participants rated their mood and performed memory and alertness tasks after listening to the beats for 5 minutes.

The researchers found that monaural beats had no significant effect on memory or alertness. However, a significant effect on anxiety was observed in those who listened to one of the monaural beats compared to a control group.

Brainwave entrainment studies

A 2008 review by Trusted Source examined the results of 20 studies on brain wave entrainment. The studies assessed the effectiveness of Brain Wave Entrainment on the outcomes of

    Cognition and memory
    Mood
    Stress
    Pain
    Behaviour

Although the results of the individual studies varied, the authors concluded that overall the available evidence suggests that brainwave entrainment may be an effective therapy. Further research is needed to substantiate this.


Alzheimer's

Since abnormalities in brain wave patterns can be detected in brain disorders and diseases, such as Alzheimer's, researchers have hypothesised that their restoration could have a preventive and therapeutic effect in diseases.

To confirm this hypothesis, researchers (H. F. Iaccarino et al., 2016) conducted a study in which they successfully exposed mice to a 40 Hz gamma wave flash. These then showed increased microglial (immune defence) activity, a reduction in amyloid beta and tau plaques in the cortex, and an improvement in cognitive performance.

In a continuing study from 2021, researchers had Alzheimer's patients apply visual and auditory stimuli at 40 Hz for one hour daily for 6-9 months.

After 6 months, compared to the placebo group, participants showed 84% slowing of functional decline (ADCS-ADL score), 83% decline in cognitive decline and memory loss (MMSE score), and 61% decline in brain atrophy and brain volume loss. This is a fabulous result!


Therapy for insomnia - Insomnia

Brainwave entrainment using external sensory stimuli is very useful to treat insomnia.

In this 2020 study, auditory, visual and haptic stimuli are used to improve the overall sleep quality of people with insomnia. Two audio signals with different frequencies were delivered to the left and right ear. The result is a binaural beat signal in the delta band. Visual signals are also given to the two eyes through an eye mask to prevent light from the outside from entering. An automated system has been developed to apply pressure to HT-7 with time and pressure control. This therapy is self-administered by the TEST group (diagnosed with insomnia) for a short period of time at regular intervals. Brain signals are recorded before and after therapy to understand the influence of AVE. Subjects who have not been diagnosed with insomnia (CONTROLLERS) will also have their sleep patterns assessed to compare baseline.

Analysis of the power spectrum of these signals shows that the average delta signal power increases by 10% and converges with the CONTROLs. The test responses are also statistically evaluated using Cohen's d-value. The results show that sleep quality improved significantly with this therapy. The subjects with insomnia who were not taking oral medication also responded better, as their rhythmic changes almost matched those of the control subjects and the duration of REM states increased significantly.
