If you search the Net for “binaural beats” you’ll promptly discover there’s a whole industry built upon the idea that listening to binaural beats may produce all sorts of desired effects in your brain.
It may alter your mood, help you abide by a diet or quit smoking, get you pumped up for a contest, calm you down, put you to sleep, heighten your memory, act as an aphrodisiac, heal headaches, and even balance your chakra.
Walking into any spa, massage centre, beauty centre and the likes, the first thing one would notice is the tranquil and quiet surroundings that are only “broken” by the equally intoxication tranquil sounding light music in the background.
Similar yet different to this is the binaural beats. The underlying reason for using this type of music is similar and so is the intended goal. Binaural beats are sounds that are supposed to stimulate the brain in specific ways. These sounds have been claimed to help induce relaxation, meditation, creativity and other desirable mental states.
The way the brain is affected depends on the varying frequencies of each tone. Each ear listens to these tones at different frequencies.
This may sound strange, but that is the basis of binaural beats. The right ear my listen to a tone of 300Hz while the left ear listens to the same sounds but at a different tone of 310Hz.
In order for the phenomenon to work the low frequency pulsations in the amplitude and sound localization of the sound must be presented separately, ideally using head phones.
Also the frequencies of the tones must be below 1000Hz for the beating to be noticeable. Also the difference between the two frequencies must be small, otherwise the two tone sounds would clash and come out sounding separately, and thus the binaural effects are lost.
Binaural beats have created much interest to those in the neurophysiological world where there is always an ongoing research investigating the sense of hearing. Binaural beats reportedly influence the brain in more stubble ways to reduce anxiety and provide other health benefits too.
Behind The Beats
Upon hearing these binaural beat the brain the processes these sounds through both spatial perception and stereo auditory recognition and then creating the responses and activations of the various points in the brain.
These activations then bring to the fore front of the brain, into the thought process the different feelings, sensations and perceptions in specific areas. Below are a few example of what one can expect to gain from the different binaural beat waves:
Gamma waves – should ideally be at the 40Hz level. When tuned to this the brain in then expected to be able simulate higher mental activity, which includes better perception, better problem solving features, better control of fear and consciousness.
Beta waves – range frequency should be between 13 – 39 Hz in order for the binaural beat to stimulate the desired results. These results are noted as an active, busy, or anxious thinking coupled with active concentration levels, arousal, cognition, and paranoia. Not altogether desirable but may have some purpose.
Alpha waves – are kept between 7 – 13 Hz in order to ensure optimum levels of relaxation while being in a fully conscious state, pre sleep and pre wake modes of drowsiness. REM sleep phase and also dream like states.
Theta waves – normally adjusted to 4 – 7 Hz which is ideal the deep meditative and relaxed levels need to be reached or achieved. It is ideal for NREM sleep patterns.
Delta waves – tunes to 4 Hz to create the natural inner self relaxed state to encourage deep dreamless sleep and loss of body awareness. This of course is ideal when an individual is seeking complete disconnection from the awareness state.
