Updated 6 October 2019
Sound healing is not new. Tibetan Singing Bowls, chanting, humming, lullabies — they’re all forms of sound that have been used throughout history for soothing, healing, or meditation. I’ve had a Tibetan Singing Bowl for almost two decades now. I meditate with it and use it to reduce anxiety during a panic attack. Unfortunately, the Singing Bowl doesn’t reduce the pain or duration of a migraine, whether it is with aura or without, nor does the Singing Bowl reduce the excruciating pain of atypical trigeminal neuralgia, from which I’ve suffered for the last two years. Because my medical massage therapist had actually used a Sound Vitality Infratonic sound wave device on some of my childhood injuries to reduce recurrent inflammation and pain, I decided to use that specific device on my head in the summer of 2018 after a three-month migraine showed no sign of ending.
My therapist was afraid to use her Infratonic device on my head: I have hemiplegic migraine that can cause seizures, and my therapist feared that the sound waves might trigger a migraine-induced seizure. In June 2018, she let me borrow her Infratonic 8000 (an older version) to use at home, cautioning me to make sure I was lying down in bed before using it on the migraine pain so that, if the sound waves did trigger a seizure, I would already be in a safe environment.
When I first put the Infratonic 8000 on my head, directly over the migraine pain, the pain increased slightly. Almost immediately, however, the pain changed in a way that’s difficult to describe. Before I’d even removed the Infratonic 8000 from my head to change its settings, the pain began to reduce in intensity. (I wrote an article detailing the treatment of that particular migraine, and another with placement suggestions for anyone else treating migraine pain with Infratonic sound wave devices.) Using the Infratonic 8000 never triggered a migraine-seizure, and because the Infratonic 8000 so noticeably reduced the pain, I started researching the science behind the sound wave device as well as how I could acquire an Infratonic of my own.
How The Chi Institute (formerly, Sound Vitality) Sound Devices Work
The Chi Institute (formerly, Sound Vitality) makes no claims that their sound wave devices heal you. Instead, their devices reduce pain and inflammation with infrasonic sound waves (varying from 8-800 Hz or cycles per second, which is below the threshold of most humans’ ability to hear), allowing your own body to begin to heal itself. The patented Infratonic is 501(k) listed by the FDA as medical massage device, though it doesn’t really “massage” your tissue. The earlier units, which plug in, vibrate a bit, but it’s not actual massage. The Infratonic 9 does not vibrate.
The newest version of the Infratonic sound wave device is a dramatic improvement over the earlier devices, which were rather large and cumbersome, and which needed to be plugged in to operate. To use the Infratonic 8000, you had to literally be within a foot or two of the device’s base. The Infratonic 8000 is no longer available for sale because the company now offers a new version: the Infratonic 9, or I-9 for short. Not only is the Infratonic 9 smaller than the previous versions of The Chi Institute’s devices, it is portable and rechargeable. The I-9 is approximately 3.5″ wide, 6.5″ long, and slightly over 1.5″ deep. It weighs 14 ounces (i.e., much less than the hardcover Lord of the Rings in one volume). The I-9 comes with its own non-padded, vinyl carrying case and AC adapter/charger.
I was delighted to learn that you do not have to have a medical massage license to purchase The Chi Institute’s Infratonic 9. You do not need your physician’s recommendation or a prescription to buy one, and you most certainly do not need the permission of an insurance company to buy the I-9 to treat your own pain.
After using the Infratonic 8000 periodically for a few years in my medical massage therapist’s office, using the Infratonic 8000 daily for a month to reduce the pain of an intractable migraine, and using the Infratonic 9 virtually 24 hours a day for the last 7 months, I can now comfortably review both the product and the company.

How to Operate the Infratonic
There are three sound wave settings on the I-9 for reducing pain and promoting healing, on the right side of the On/Off button, operated by the Signal button after you turn the I-9 on. Each setting has its own frequency of sound waves.
- Balance (which some medical massage therapists call “body”): soundwaves at 8-17 Hz
- Acute (which some call “body and mind”): soundwaves at 8-50 Hz
- Deep Calm (which some call “spirit”): soundwaves 8-800 Hz
To the left of the On / Off button is the Timer button: the I-9 has two pre-set timers, for 10 or 20 minutes each, which also operate with an electronic alarm (which sounds just like the device when you turn it on). The timed settings, with or without alarm, shut the device off automatically after designated 10 or 20 minutes.
To run the device on any setting — Balance, Acute, or Deep Calm — continuously, press the Timer button until all the lights on the left side of the control panel are off. The device will run continuously until you manually turn it off with the On / Off button in the center bottom.
The I-9 has a rechargeable battery (life expectancy = 3 years) and a plug-in adapter/charger. It took 45 minutes to charge it the first time (their site says it takes 90 minutes). You can safely use the I-9 while it is charging, but don’t put it under a pillow when it’s plugged in and charging as the I-9 gets hot to the touch when plugged in and under a pillow. Sound Vitality estimates 60-65 hours of continuous usage from one battery charge: I’ve gotten as much as 2.5 days of continuous use before the unit alerted me, with a noise and the battery light, that it needed to be recharged.
The Battery light in the center of the control panel only operates when it needs to be charged, in which case it will glow red, or when it is charging, also red. The Battery light turns green when it is fully charged and goes off when you unplug the unit.
The sound waves are emitted from the underside of the I-9, which looks like the grill of a fan. No air comes out. The I-9 has a patented Chaos system that makes the sound waves come out in a “chaotic pattern” so that your brain and body cells cannot accustom themselves to the sound waves. If your cells can find the pattern, they can replicate it, which allows the damaged cells to remain damaged.
If you hold the I-9 to your ear, you might hear the sound of the Chaos-mechanism whirring slightly, but you have to have exceptional hearing, i.e., beyond the usual human range, to hear the sound waves themselves. Horses and dogs can hear the sound waves. I think my cats can, too. I hear something beyond the Chaos mechanism on both the Acute and Deep Calm settings, but most people hear no sound when they put the I-9 up to their ear.
You can place the Infratonic directly on bare skin: it will not burn you or heat up. You do not need any gels or lotions for the sound waves to pass through your tissue and bone; further, I wouldn’t advise putting the I-9 on top of gels or lotions since those might damage the machine by getting inside. You do not have to take breaks from using the I-9: I’ve used it the entire 9 months that I’ve had the migraine that is being triggered by the trigeminal neuralgia, including when I sleep, and I’ve been using the I-9 specifically for the atypical trigeminal neuralgia for over six months, 24 hours a day, 7 days a week (during the day, I wear it in a headband-sleeve that I made for the device; at night, I put it under my pillow).
What’s In the Box
• the Infrantonic 9
• a non-padded, vinyl, zippered carrying case
• plug-in adapter for recharging the battery
• a handbook of testimonials from customers
For such an expensive device, the carrying case is pretty cheap and flimsy. It is not padded in any way. To carry the fully charged Infratonic device with me in my purse or backpack, I put it into a sturdier, fully lined, padded leather pouch.
Since the AC-adapter/charger doesn’t have retractable prongs and doesn’t fit in either the original carrying case nor in my leather pouch, I’d put the Infratonic 9 in my padded, suede, iPad-mini case if I were traveling, if only because that case has a separate zipped outer compartment where I could safely store the adapter/charger.
The adapter could have been improved by having retractable prongs, but it would have been even better to have a USB adapter and a separate plug (with retractable prongs). A USB-adapter/charger cord would easily fit into the vinyl carrying case that comes with the device as well as into the smaller leather case I have. A USB-adapter/charger would not scratch the I-9 itself as the attached-plug charger could if it were forced into a case with the device. This type of adapter/charger would also allow the device to be charged at home and at work, for instance, without requiring you to carry around the bulky plug.
Warranty and Customer Service
The Infratonic 9 has a 30-day Unconditional Return Guarantee and 1-Year Warranty on Parts & Labor from The Chi Institute itself. Mine behaved strangely the first few days: it kept sounding the alarm and shutting itself off randomly. The Chi Institute paid my return shipping, replaced the circuit board and battery, and shipped the repaired I-9 to me, all free of charge. After it was returned to me, I used it over 6 months, virtually continuously, and it worked perfectly. Until it began misbehaving again: shutting itself off randomly, only without its customary warning beep.
At the end of the seventh month of constant usage, the light indicating that the battery needed to be charged on my I-9 began coming on in less than 24 hours — far shorter than the 48-60 hour charge time I’d been used to — and the unit began turning off and on and off again, by itself, but without the customary warning beeps. When I contacted Sound Vitality’s customer service about buying a new battery, they informed me that the battery should last 3 years. They talked me through some trouble-shooting tips to reset the device, and mailed me a replacement battery free-of-charge. After the trouble-shooting, which I was easily able to do myself, the device stopped randomly turning itself on and off. Once I installed the replacement battery, the device returned to its original 48-60 hours of operation before needing to be charged.
Update: My original device began behaving erratically, once again, in April 2019, less than a year after purchase, and still within the warranty period. The device kept turning itself off randomly but without the usual accompanying warning beep. It was also taking about 8 hours to charge, despite the newly installed battery. Sound Vitality sent me a demo device as well as a new plug, along with a shipping label to return my defective unit. As of this date, The Chi Institute has decided to keep the defective unit while I will keep the demo unit, which is performing marvelously and is greatly reducing my pain. I am beginning to have a few hours each day completely pain-free: there is still pressure in my head and face along the middle and upper branches of the trigeminal nerve, but I consider pressure-only an great improvement in the chronic pain.
The Chi Institute has very good customer service, and someone is available to answer questions by phone or online chat to help you with your device.
The Chi Institute Sources of Infratonic Information
If you have questions about the I-9 itself, the customer service department at The Chi Institute is happy to answer you via online chat or by phone at their toll-free number. They have a former website at Chi Institute, which has several articles on the 30-year history of the Infratonic, on how infrasonic sound waves work healing injured horses, on how the Infratonic reduces pain and cellular trauma, and how the Infratonic device accelerates recovery. The Hospital Protocol pages lists some of the types of injuries and tissue damage for which the Infratonic may be used. The Chi Institute also has testimonials on its site about the type of conditions the Infratonic machines have been used to treat.
Their older website has some diagrams about using the Infratonic (all versions), but I actually found it more effective when I just put the Infratonic (whether the older 8000 model or the latest model I-9) on the pain itself, as well as on any areas that might be contributing to the pain. The Infratonic Therapy User’s Guide for the I-9 is 110 pages of testimonials from customers who have used it on themselves or their animals, for injuries, surgeries, etc. You can read the entire guide online.
The Chi Institutte (formerly, Sound Vitality) has a video on the I-9 settings and timer, a brief video tip on using the I-9 for sleep, a very brief video mentioning the I-9 for headache and migraine, and a 48-minute webinar on treating various injuries and illnesses with the I-9, but there are no detailed instructions on how to specifically use the I-9 to treat specific injuries beyond “put it where it hurts” and “chase the pain.“
I had to figure out where to use the Infratonic for migraine pain myself. That’s why I wrote my first I-9 article: I would have loved to have found such a detailed article when I was researching ways to reduce migraine pain with sound waves, and I wanted to share what worked (and what didn’t) with others suffering from migraine.
Final Evaluation of The Chi Institute’s
Infratonic 9 Sound Wave Device
My main purpose in using the Infratonic 9 sound wave device is to reduce and eliminate chronic and acute (sometimes excruciating) pain: the I-9 scores extremely high in that area. It reduces both chronic and acute pain almost immediately. I have been using The Chi Institute’s Infratonic sound wave devices continuously since Jun 2018, for migraine without aura, hemiplegic migraine, and atypical trigeminal neuralgia. Since August 2018, I have been using the Infratonic 9 constantly for the atypical trigeminal neuralgia. I even made a pocket for the device out of a sport’s headband, and I pin the device-in-the-pocket to another sports headband, and wear the I-9 all day long, over the area of the damaged trigeminal nerve. At night, I sleep with the I-9 under my pillow, vent side turned upward.
The I-9 reduces the duration of hemiplegic migraine attacks and enables me to use less pain medication (though I still have to stay in bed). After 3 months of continuous usage, the Infratonic sound wave devices enabled me to differentiate the migraine without aura that was being triggered by the atypical trigeminal neuralgia, the hemiplegic migraine attacks, and the unremitting pain of the atypical trigeminal neuralgia. The I-9 also has reduced the frequency and the excruciating lightning-bolt pain of the trigeminal neuralgia. For the last week, I have had several days when I was relatively pain-free for several hours at a time: when I tried not wearing the I-9 a couple mornings this past week, I had severe pressure in my face from the atypical trigeminal neuralgia and some excruciating breakthrough pain, but nothing I couldn’t handle with several aspirin, herbal supplements, and brief usage of the I-9.
The Infratonic 9 has given me hope that I will one day be pain-free.
Having used the Infratonic 8000, which is most decidedly not portable, the newer I-9 scores high with its portability and light weight. Considering the fact that I’ve been able to actually get out of bed regularly the last few months, despite continuing pain, by literally wearing the I-9 (in the headband-sleeve, attached to another sports headband worn around my forehead), the smaller size, lighter weight, and portability of this newer device rate very high.
The I-9 was relatively easy for me to use, but I may be more familiar with all types of electronic devices than some people. Considering the fact that there are I-9 videos which demonstrate how to actually use the I-9, there are obviously some people who don’t understand its working mechanism. Sound Vitality would do well to have an instruction sheet on the device’s basic operation, especially if they wish to have people who are not medical massage therapists using the device on themselves.
More important than even a padded carrying case that would hold both the device and its adapter/charger, Sound Vitality needs to provide an owner’s manual that instructs us in how to treat chronic or acute pain with the I-9 sound wave device. Because I have been going to medical massage therapists for over two decades, and because I have purchased many medical textbooks to help me learn how to treat my own chronic pain, I was a little more informed about treatment areas for the pain of migraine and atypical trigeminal neuralgia than other consumers may be. However, I had to basically teach myself how to treat the damaged areas with the Infratonic 9. Some treatment areas reduced the pain, some didn’t have any effect on the pain (though, at least, treatment on these areas did not increase the pain). I would have greatly appreciated having an owner’s manual that gave me some rudimentary advice about I-9 placement (such as in my first article on the Infratonic 9).

Purchasing an Infratonic 9
I first had experience with an Infratonic 8000 in my medical massage therapist’s office, who told me that she had first used one on herself at the office of another medical massage therapist before she purchased an Infratonic for her office.
I realize that this is a rather expensive unit, and if I hadn’t used it in my medical massage therapist’s office for a recurring injury and its pain, I would have hesitated even longer about buying my own. My research into sound healing and The Chi Institute’s 30-day money-back guarantee convinced me to purchase my own I-9, and I was saving the money to buy it when I learned that The Chi Institute allows you to make a purchase via PayPal Installment.
You do not need a physician’s prescription or a medical massage license to purchase an Infratonic 9. I am not aware of any insurance companies’ covering the cost of the device, although you can purchase an I-9 with the funds in a Health Savings Account (HSA) if you have one.
If you have any questions about using the Infratonic 9 for pain relief, please feel free to ask me in Comments to this post, on Twitter or on Facebook, or in an email via the Contact page. I’ll do my best to help you figure out how to use the Infratonic 9 to help you reduce your pain.

Infratonic 9 *
My Infratonic 9 was purchased directly from The Chi Institute (formerly, Sound Vitality). I have not received any sort of compensation for this review, nor have I received any compensation for any of my other articles about my experience treating migraine and atypical trigeminal neuralgia with the Infratonic 9. I did all the research on sound healing, ultrasound, infrasound, and Chi-sound machines myself, both before and after my Infratonic 9 was purchased. When I had some questions about the frequencies of the sound waves, I contacted Sound Vitality, and their Director told me the specific ranges of the sound waves, as well as why the Chaos mechanism was added to disrupt those sound waves for healing purposes. I learned everything else from my own research and my own experience with the Infratonic 8000 and the Infratonic 9, and that includes all the suggested placements for pain relief and treatment in the Related Posts (below).
The Infratonic 9 by The Chi Institute can be purchased directly from their site. After you have the item in your cart, you can choose Pay with PayPal if you wish to pay in installments. You will then be taken to PayPal’s site, where PayPal handles all the financial information and installment arrangements. Otherwise, you pay with a credit or debit card.
The Infratonic 9 it is also sold by The Chi Institute through Amazon, which lists the same device three different times (all at the same price): for sports injuries recovery, abdominal pain relief, and menstrual cramps relief. They are all the same device, though the photos make the device look slightly different, If you buy the Infratonic 9 from Amazon, The Chi Institute will be sending your device. This is the I-9 that I use for the pain of migraine and atypical trigeminal neuralgia.
