40 hz sound therapy

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.

Advocates of this type of therapy currently recommend it for the treatment of anxietystressand related disorders. This self-help treatment is usually available in the form of audio recordings that a person listens to on stereo headphones. However, research is inconclusive about the clinical benefits of binaural beat therapy, and a doctor does not oversee its delivery.

Therefore, it is best not to replace traditional treatments for stress and anxiety with this type of intervention. Binaural beat therapy is not part of standard care for any condition. Doctors consider this treatment to be semi-experimental. In this article, we explain binaural beats and look at current research to assess their effectiveness. We also clarify how to use them.

According to a literature reviewthe tones should be at frequencies lower than 1, 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 Hz and the right ear registers one at Hz, the binaural beat is 10 Hz — the difference between the two frequencies.

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. However, a 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. To listen to binaural beats, a person will need a pair of stereo headphones and an MP3 player or another music system. As the leading authorities in psychiatric treatment have no recommendations for binaural beats, it is usually the producer of the tape that makes the suggestions for use.

People should follow the instructions 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. Early research from suggested that binaural beat therapy may yield some benefit for people with mild anxiety. However, the authors stated that it warranted further study only as a therapeutic measure to support conventional treatments for anxiety.

Despite this, other researchers have continued to investigate this therapy. A study involving more than participants who were due to receive general anesthesia for a day procedure reported a decrease in preoperative anxiety after exposure to a delta wave binaural beat.Could an hour's exposure every day to a specifically calibrated flickering light and droning sound help clear your brain of the toxic proteins that cause Alzheimer's disease?

An intriguing new MIT study raises this possibility after successful mouse experiments showed marked neurological improvements through simple visual and auditory stimulation.

These gamma oscillations can range anywhere from 25 to Hertz, but there has long been a hypothesis that 40 Hz is the magic frequency for optimal brain functioning.

Using optogenetic technology the researchers specifically stimulated individual neurons in an animal's hippocampus, discovering dramatic reductions in both amyloid and tau proteins after just one hour of stimulation at 40 Hz. Fascinatingly, the researchers then discovered similar effects could be generated in the mouse brain through simple external exposure to a light flickering at 40 Hz.

In a newly published study the MIT team explored the effects of adding sound stimuli to the treatment. The results reveal similar effects, with an hour's exposure to 40 Hz tones per day significantly reducing amyloid build-up in both the auditory cortex and hippocampus of mouse brains. When we combine visual and auditory stimulation for a week, we see the engagement of the prefrontal cortex and a very dramatic reduction of amyloid. The dual visual and auditory treatment proved much more effective than each stimulation by itself.

The broader neurological effects of this combined treatment demonstrated enhanced microglia activity in the prefrontal cortex.

This suggests the body's innate immune response was heightened by the external stimulation. The exciting results are not without significant limitations. A large amount of the beneficial effects from the stimulation treatment noticeably faded one week after the treatments had been stopped, meaning there may not be any long-term benefits from the stimulation.

It is also unclear exactly why 40 Hz is the perfect frequency to generate these effects, so further study is needed to uncover the molecular mechanisms behind this particular phenomenon.

Underlying all these limitations is of course the fact that the research so far has only been established in mouse models. The entire field of Alzheimer's research is filled with studies that proved promising in animal models, yet could never be replicated in humans. The research team has already conducted safety tests in humans for the combined visual and auditory treatment, with enrollments underway for a larger trial targeting early-stage Alzheimer's patients. It conceivably will take years to ascertain how effective this technique is in slowing, or reversing, Alzheimer's symptoms in humans, but it is undeniably a fascinating hypothetical treatment.

They'd be exposed to it many hours per day, whole year, no problem if the effect fades in a week. You'll never see it as it might actually cure a disease. Did you ever notice how the medicals and drug dealers stopped curing disease with Jonas Salk curing Polio?Joel, thnx for this link. I have heard that once a cure is found for ALZit wouldnt be long before a cure for PD s available and visa versa.

Hi, My GP suggested I research the 40HZ sound waves because of the apparent affect in our brains, causing more activity.

Unfortunately, I found nothing that specifically pertained to PD. However, I will keep looking, since new methods etc, are being developed every day. Ruth, plz keep us posted on what you find.


I am doing an unscientific i. Just finished the logistical part of it, good to go starting today or tomorrow. Plan is 1 hour per day. Anyway, will provide more feedback on this going forward if anyone is interested. I did not see any significant scientific study supporting either light or sound as an agent for neuroprotection the Holy Grail.

And then there was the article that seemed to be based on the premise that much of Parkinsons was caused by toxins.

Bottom line: All very interesting. Neither light nor sound Tx seem to have any significant side effects unless you have trouble with modern rock music!

I have spent a small fortune on Rx drugs, to no avail. I have been doing the infrared helmet since May and I believe it may be helping my sleep, although I cannot say for sure. Until the cause of PD can be identified, I dont think we will have an effective treatment for all of us. That is why I have donated my brain to PD research so that others may benefit in the future from what may be learned. It is the only way to tell scams from valid therapy options, from those treatment possibilities that are too early to tell.

Andrew L. Has anyone found any indication that one part of the light spectrum might be preferable to the rest?

Hi Joel; am personally unaware of the benefit of one part of the light spectrum vs.We've developed affordable, precisely-tuned 40Hz devices for those trying to promote gamma brain waves through entrainment. We currently offer both a 40Hz light kit and 40Hz audio device.

Our products are assembled and calibrated in the United States. Available for purchase today! Right out of the box, you, a loved one or friend will enjoy the potential benefits of gamma 40Hz therapy. Current research suggests that exposure to a light or sound at 40Hz 40 times per second promotes gamma brain wave activity through the entrainment phenomenon.

This research indicates that the increase in gamma brain waves could be used as an alternative therapy for many hard-to-treat brain diseases. One of the most promising areas of interest is the use of waves to activate critical cleaning cells in the brain that could lessen beta amyloid.

Far be it from me to take away from all these worthwhile applications, but last week, I got a message from Dennis Tuffin of Devon, Englanddescribing a new use for my generator which may very well trump everything else:.

I have been following up on some research which my daughters had done about the treatment of Alzheimers by using a 40Hz flickering light source or alternatively a 40Hz sound source. There is sparse info on the net about these experiments though there is a recent piece about it. So I have continued to use your tone generator using a 40Hz sine wave for about an hour each day.

I found it necessary to connect external speakers to my laptop in order to pick up such a low note and to run it at a level of between decibels so that she hears it wherever she is in the room.

Dementia sufferers get very fidgety! So now 7 weeks on the improvement in her awareness has continued to the point where she is starting to be able to put a few words together and to respond to questions neither of which she has been able to do for nearly a year. Her odd physical habits have not been changed so far but she is definitely walking better and not shuffling her feet as she used to.

The setup used by Dennis. The black box on the left is the external speaker. To date I have not gone public on this and only close family have known but by the end of another week when it will be 8 weeks since we started I think I would like to spread the word and hopefully prompt a few professionals to do more proper research. Dennis, the reader from the UK who piqued my interest in this subject, used a pure 40 Hz tone. According to this AlterNet article later reprinted by The Salona pure tone was used in the preliminary safety study done by Cognito in early On the other hand, it appears that the most recently published MIT study used series of clicks despite previous reports rather than a tone.

The New York Times quotes Dr. However, in response to my inquiry, another co-author of the paper, Ho-Jun Suk, said that 40 Hz pure tones were not used because mice cannot hear tones of such a low frequency. It would be very interesting to know what sort of tones are being used in the now ongoing human trials.

The New York Times and the Boston Globe published articles about the MIT mice study, including links to audio samples of the stimuli that were used by the researchers. Unfortunately, I have discovered that neither sample represents accurately the audio waves that were played to the mice. The clicks in the published samples are smeared in time closer to 2 ms and are not pure 10 kHz tones.

Ho-Jun Suk has confirmed that they do not match the source signal. If you are thinking about using clicks rather than pure tones, I would not recommend using 10 kHz clicks because human ears are not very sensitive to that range of the spectrum.

Something like 3 kHz where human hearing works the best would probably be more sensible. Getting a 40 Hz tone is easy — you can use my frequency generator.

Please note I do not take responsibility for the purity of the produced tone, as it is generated by your Web browser — though I think it should be fine. By the way, I am also not a doctor and I am not giving medical advice or offering any medical product here. You will need decent speakers. If you try anyway, you will either hear nothing, or you will hear mostly — or only — distortion.

What is distortion? A bookshelf speaker photo: D. Bookshelf speakers will do 40 Hz, but their output at that frequency will be significantly reduced, so you will need to turn up the volume significantly, and they will produce easily audible distortion. Because the ear is more sensitive to high frequencies, the distortion may be subjectively louder than the fundamental 40 Hz tone, and may make the sound harder to tolerate, thus limiting the volume and possibly the therapeutic effect.

The best solution is a high-quality subwoofer. This will give you as pure a tone as you can get. For the maximum boost, put the speaker s on the floor, in a 3-way corner between two walls and the floor — that way, it will be adjacent to three surfaces.

How important is sound quality? Dennis seems to have had great results with cheap computer speakers. It is not known to what extent the therapeutic effect depends on volume or the presence of distortion.Skip to main content. Listen Now.

A recent study found that sitting down patients in a chair with built-in speakers and subjecting them to sound stimulation at 40 hertz had "promising" results in terms of increasing their cognition, clarity and alertness. The research, which was undertaken by researchers from the University of Toronto, Wilfrid Laurier University and the Baycrest Centre hospital in Toronto, studied the effects on 18 participants with different stages of the disease six mild, six moderate and six severe after six sessions of treatment.

They also received a second round of treatment through visual stimulation on DVDs, also across six sessions. They found that the 40 Hz stimulation had the strongest impact on patients with mild or moderate Alzheimer's disease. While the study's sample size is small, Lee Bartel, one of the authors of the study says the findings are encouraging. Bartel said the study saw some of the participants with mild Alzheimer's return to being "normal again," and those in moderate condition see their symptoms be downgraded to mild.

Amy Clements-Cortes, another one of the authors and senior music therapist at Baycrest, was also hopeful about the study's findings. Bartel said he came up with the premise of the study after seeing research from the s that Alzheimer sufferers have a lower frequency pattern at which neurons interact in the central nervous system.

In healthy people, the pattern, or gamma frequency, generally hovers around 40 Hz. Bartel compared it to the need for wireless telephones to function at the same frequency in order to communicate. Bartel said the sound-stimulation treatment at 40 Hz leads to an "increased" frequency, which allows "parts of the brain to talk to each other again.

Bartel said the body's cells proceed to relay the frequency to the sensory-motor and auditory cortices to "reregulate" the brain. Despite the treatment being relatively non-invasive, there are some risks, according to the authors.

Bartel said the magnets in the chair's built-in speakers could pose problems for people with pacemakers. The vibrations could also be dangerous for people with blood clots or strokes. The authors also don't recommend the treatment for pregnant women. While Bartel admits the treatment is likely not the "cure for Alzheimer's," he and Clements-Cortes said it could be a "relatively inexpensive" way for people to treat themselves at home.

The University of Toronto is also hosting a showcase for the study, and other breakthroughs that combine music and science, at an event on May 3.
