Yet, given that we do not have a generally accepted definition of what brainwave entrainment in response to binaural beat stimulation actually is, the question of operationalization is not settled in principle. This points to a need for a comprehensive theoretical and methodological debate about the definition of brainwave entrainment which should result in an alignment with respect to EEG measures to assess entrainment effects. Binaural beats, when tuned to an adequate frequency, are theorized to encourage the brain to gradually transition from a more alert, higher-frequency state into a slower, more relaxed one. Some small studies have supported this theory, while others have found evidence that the changes in brainwave patterns may also trigger hormonal changes—including increased levels of melatonin and DHEA and decreased cortisol levels. People who use binaural beats may report feeling more relaxed, seeing improvements in mood and motivation, experiencing increased focus and lower anxiety, and sleeping better.
Alpha waves are a type of brain wave that typically occur when the brain is in a relaxed yet alert state. These waves are associated with increased focus and concentration, making them an important factor in cognitive functioning. When our brains produce alpha waves, we are more likely to be able to block out distractions and maintain our attention on a specific task.
Do Binaural Beats 9Hz-12Hz Stimulate Alpha Waves?
In view of this, the need for a systematic analysis and integration of the current state of research becomes evident—even more so in consideration of the fact that binaural beat stimulation is regularly used in applied contexts [1, 31, 34–46]. However, there is inconclusive research supporting binaural beat as a stand-alone medical treatment tool. Binaural beat therapy can’t be used in place of conventional therapy, but it could be used as a complementary strategy if discussed with a doctor. Research shows that binary beats are good for mental health as it’s linked to encouraging positive feelings. Some people who listened to binaural beats experienced short bursts of anxiety, anger, and confusion that lasted for a short time. Some studies have linked binaural beats to increased feelings of depression.
While still a controversial subject, a controlled placebo study done in the 90s with EEGs has shown “an increase of EEG alpha power, correlating with intense euphoria, was found after smoking marihuana“. Dreaming (REM sleep), deep meditation, increased production of catecholamines (vital for learning and memory). After the neurofeedback training session ended, the researchers asked subjects to perform two additional tasks that involve attention, and found that the enhanced attention persisted.
There has been some research suggesting that binaural beats in the frequency range of 9Hz to 12Hz may indeed stimulate the production of alpha waves in the brain. This means that listening to binaural beats within this frequency range could potentially help individuals enhance their focus and concentration levels.
A healthcare professional can provide an accurate diagnosis and a personalized treatment plan based on an individual’s specific needs and goals. The effectiveness of accessing the subconscious mind depends on individual preferences and the specific goals of the practice. Some individuals may find success with alpha or theta states, while others may prefer delta states. It’s essential to experiment with different techniques and frequencies to find what resonates best with you. High gamma waves indicate the ‘fight or flight’ state, one of stress and anxiety.
While more research is needed to fully understand the relationship between binaural beats and alpha waves, there is some evidence to suggest that they may have a positive impact on cognitive performance. So, if you’re looking to boost your focus, incorporating binaural beats into your routine could be worth exploring.
With alpha brain wave work and other psychological techniques, you may develop your ability to tap into the power of your brain now and in the future. Daydreaming can produce alpha brain waves, but how do you make yourself daydream? You might sit calmly with your eyes closed and allow your thoughts to wander. If you begin to daydream, try letting it happen without shaking yourself out of it. Brain waves are electrical impulses that can flow from neuron to neuron within your brain. Neurons are the brain cells that typically send and receive electrical and chemical signals.
Neurofeedback is a type of biofeedback where you respond in real time to the electrical activity in your brain and try to adjust it. When you’re sleeping more lightly or when you’re extremely relaxed, your brain may produce more theta waves. Brain waves are measured by frequency, which is cycles per second, or hertz (Hz), and they range from very slow to very fast. Alpha waves fit in the middle of the spectrum, between theta waves and beta waves. Interestingly, a 2009 study suggests that your brain may produce even more alpha waves in the posterior part of your brain when you meditate. Your brain isn’t totally at rest, but it’s not attempting to tackle anything big that requires concentration.
