Binaural Beats Therapy: Benefits & How they work ?

Binaural beat therapy is an emerging form of sound wave therapy. It makes use of the fact that the right and left ear each receive a slightly different frequency tone, yet the brain perceives these as a single tone.

This type of therapy is recommend  for the treatment of anxiety, stress  related disorders. This treatment is usually available in the form of audio recordings that a person listens to on stereo headphones.(Not Mono cuz one have to listen with both the ears , WHY !? CHECK BELOW )

NOTE : 

Binaural beat therapy is not part of standard care for any condition. Doctors consider this treatment to be semi-experimental.

How do binaural beats work?

According to a 2015 literature review, the tones should be at frequencies lower than 1,000 hertz (Hz) for the brain to detect the binaural beat. The binaural beat that a person perceives is the frequency difference between the waves entering the left and right ear.

For example, if the left ear registers a tone at 124 Hz and the right ear registers one at 114 Hz, the binaural beat is 10 Hz — the difference between the two frequencies.

 2018 study suggest that listening to binaural beats for a recommended period can affect a person’s subsequent behaviour and sleep cycles.

Patterns :

The study authors explain that there are five different categories of frequency pattern:

• Delta pattern: Binaural beats in the delta pattern operate at a frequency of 0.5–4 Hz with links to a dreamless sleep. In the study, people who received a delta pattern frequency during sleep entered a deeper stage of sleep, according to electroencephalogram (EEG) brain scan results.

• Theta pattern: Practitioners set binaural beats in the theta pattern to a frequency of 4–7 Hz. Theta patterns contribute to improved meditation, creativity, and sleep in the rapid eye movement (REM) phase.

• Alpha pattern: Binaural beats in the alpha pattern are at a frequency of 7–13 Hz and may encourage relaxation.

• Beta pattern: Binaural beats in the beta pattern are at a frequency of 13–30 Hz. This frequency range may help promote concentration and alertness. However, it can also increase anxiety at the higher end of the range.

• Gamma pattern: This frequency pattern accounts for a range of 30–50 Hz. The study authors suggest that these frequencies promote maintenance of arousal while a person is awake.

Benefits

The purpose of using binaural beats therapy may differ among individuals. Some people may need help decreasing their anxiety, while others might want to increase their concentration or deepen their level of meditation.

Binaural beat therapy suggest that the potential benefits include:

• reduced stress and anxiety
• increased focus, concentration, and motivation
• improved confidence
• better long term memory after exposure to beta pattern frequencies, according to a 2019 study
• deeper meditation
• enhanced psychomotor performance and mood

However, a 2017 study that measured the effects of binaural beat therapy using EEG monitoring found that binaural beat therapy does not affect brain activity or emotional stimulation. The researchers also monitored heart rate and skin conductance as indicators of emotional arousal.

How to use Binaural Beats  ⇩ :

To listen to binaural beats, a person will need a pair of stereo headphones and an MP3 player or another music system.(You will get playlists of Binaural Beats in YouTube , Spotify or any music streaming app in the play store )


People should follow the instructions from the producer of the beat carefully. Those who do not see any reduction in anxiety might benefit from trying a different producer, type of sound, or frequency.
It is important to avoid using binaural beats therapy while undertaking tasks that require alertness and full attention, such as driving.
