Once they had generated audio files based on the signals , the team asked hundreds of native English speakers to listen to the output sentences and identify the words from a set of 10, 25 or 50 choices.
The listeners transcribed 43 per cent of the trials perfectly when they had 25 words to choose from, and 21 per cent perfectly when they had 50 choices. One listener provided a perfect transcription for 82 sentences with the smaller word list and 60 with the larger. The team also asked one person to mimic speech by moving their mouth without making any sounds.
The system did not work as well as it did with spoken words, but they were still able to decode some intelligible speech from the mimed words. Turning the brainwave frequency into sound consists of modulating the carrier at a frequency equal to the brainwave. In other words, you will add some motion to the carrier that will be synchronized to the brainwave frequency of interest.
The carrier is the medium. The modulation is the information to be carried to the brain. Putting the carrier into motion is achieved through the modulators, described next.
We are providing four different modulation schemes. You can use them separately, or mix them to your liking. Used on its own, it creates the so called isochronic tones, or monaural beats. Isochronic tones produce strong beats, and are recommended when you work with a single loudspeaker. These carriers are detuned by an amount equal to the modulation rate. This detuning creates faint beating inside your head.
Compared to amplitude modulation, the beating is much weaker, and is best audible with a low carrier frequency. Since the beating is a sort of illusion created in your brain, people find binaural beats to be very effective though they aren't much audible.
For this to work, you need to use two speakers — left and right channels — or headphones. This modulation scheme is the one used to produce the so-called bilateral beats.
Frequency modulation is seldom used in brainwave entrainment programs, though it probably produces the most pronounced audible effect. Like amplitude modulation, it works fine when you have only one speaker on hand.
Rest assured, you don't need to understand how each modulator works. You can tweak the sliders to your liking, without much understanding of what you're doing. What is important is to hear the brainwave frequency modulating the carrier frequency. Brainwave Entrainment The brainwave entrainment - or brainwave synchronization - refers to the capacity of the brain to naturally synchronize its brainwave frequencies with the rhythm of a periodic external stimulus, such as the sounds this website produces.
Does it effectively work? It is hard to tell. It is a very popular technique though. If it didn't work at all, there wouldn't be such keen interest around brainwave entrainment, and binaural beats in particular. Some people even call these 'digital drugs'! As a scientist, I make a point of not making any false claim on this website. To the question, "Does Brainwave entrainment effectively work?
That feedback spawned the creation of this site, Brainaural - a more efficient version of what is offered at myNoise. So, it could be that brainwave entrainment indeed works as advertised. Or, it could be a placebo, but then, a powerful one. Placebo is scientifically proven to an extremely high degree. By increasing specific brain waves e. Motivation : If you want to increase your neurological and psychological motivation, this software has some tools to help.
You may find that certain entrainment sessions help you feel more motivated. Relaxation : For those who just want to relax, Neuro Programmer comes with built-in sessions to help you wind down after a long day at the office. One of the most practical uses for this software is to increase your natural capacity to just relax. Sleep deeper : While sleep quantity can be beneficial, one overlooked aspect of sleep is quality.
Individuals that have a difficult time staying asleep throughout the night e. While no brain wave is superior than the others, overabundance of beta waves may continue to keep you stimulated.
Targeted brainwave changes : If you get a QEEG assessment and determine deficiencies or abnormalities in your brain wave activity, you can use this software to make tweaks. For example, if the neurologist determined that you had inadequate beta activity, you could use this software to boost your beta waves. While many people like using brainwave entrainment products e. Holosync , this product is less costly and can be used for activities outside of meditation.
These courses are seriously flawed in that they assume everyone should go through the same progressions and be entrained the same. Since everyone is different and not everyone needs to entrain theta waves, Neuro Programmer allows you to find the session that best suits you as an individual. Plus you are not limited to just binaural beats as you would be with other entrainment programs.
I have been using the Neuro Programmer software for years with some successes and some straight up bizarre perceptual experiences. When I first tested the software in , I thought that it was nothing more than a sham. However, I took the developers up on the trial period and noticed that certain frequencies helped my chronic insomnia.
I began entraining alpha waves at night before bed to help me transition from a stressed-out beta state to a hypnagogic state to enhance my sleep quality. I also have found entrainment to be effective for relaxation and exploring altered states of consciousness. Not all of my experiments with this software were pleasant, in fact I vividly recall entraining a certain set of slow frequencies in and feeling perceptually amiss.
Fortunately time heals all wounds and brain waves and I eventually recovered from my altered state to homeostasis. He experimented with some high beta frequencies and ended up feeling extreme anxiety to the point that he felt uncomfortable in social situations and this dude is a social butterfly.
His experience was like mine in that it took awhile before he recovered from the adverse reaction to the entrainment. I believe that Neuro Programmer played a pivotal role in helping me overcome PTSD as well as adrenaline addiction by reducing my arousal. Once I figured out what frequencies worked best for my brain, I stuck to those and kept noticing that my mental arousal continued to decline.
Eventually my autonomic nervous system caught up to my neurological relaxation and began reducing sympathetic activity and increasing parasympathetic activity. I continue to tinker with Neuro Programmer on occasion, and am glad that this technology exists. You can be as skeptical as you want to be, I was highly skeptical when I tested this product. Brainwave entrainment may not work for everyone and certain people may respond better to specific frequencies than others.
This product is not intended to replace, treat, or cure any medical condition. However, some people have found certain entrainment sessions to be an effective adjunct option. In these anecdotal cases, it is important to consider the possibility of a placebo effect.
There may be some concern for those without fully developed brains e. Women who are pregnant are advised to avoid using the software, as are all individuals under the age of Anyone that has experienced seizures or is prone to seizures should avoid using the software as it may trigger seizures via alterations in electrical activity. The developers are so confident in their product, that they give you access to the full smorgasbord of features before you even consider making a purchase.
I prefer the advanced version, but the basic version is still impressive. This software could theoretically be used for the rest of your life to benefit your brain and mental performance. Do yourself the favor and at least check it out. Note : Only available for Windows operating systems. I have a Linux computer without OS. Does that mean I will never be able to use this kind of Neuro Programmer? Many thanks for sharing this link. I am planning to buy a copy of the music they are selling.
So, she is left with this condition and what are we to do? I found your articles very informative esp. How can I learn more about it? Necessary cookies are absolutely essential for the website to function properly.
