Acoustic Meridian Intelligence Devices

Each of the AMI devices, invented by Dr. Mandara Cromwell, provide frequencies that restore balance to the body with quick and easy-to-use thirty-minute channels. The design of the devices and Acoustic Meridian Intelligence concept are based on the idea that specific healing frequencies can travel the meridian pathways of the body. The AMI devices use ancient healing techniques, (as referenced in Chinese medicine and Ayurveda), combined with advanced sound technology, applying sound trans-dermally to the body through the feet or hands.

The AMI instruments can be easily implemented into existing professional healthcare practices—such as integrative medicine, chiropractic, acupuncture and massage therapy—along with health spas and fitness training facilities.

Sound therapy can be used in times of health to increase vitality and functionality– or in times of health challenges to assist the body in its healing process. The AMI devices have channels to support all aspects of health.


Mandara Cromwell, DCM,  inventor of the AMI devices, further evolved the frequency research of British osteopath, Dr. Peter Guy Manners, taking the concept of applying sound trans-dermally to a whole new level. The AMI devices emit frequencies bi-laterally, sending the healing messages throughout the human form within minutes. This innovative design replaced the need for an applicator, which could only apply one set of frequencies at a time to one area of the body .

Dr. Cromwell’s study of Ayurveda and Chinese medicine expanded the concept of frequency healing to include all the aspects of the human form—physical, etheric, mental, emotional and spiritual. Therapeutic sound has proven to have a positive impact on all areas of life, with the use of the AMI concept and devices.

These revelations in the sound healing arena have changed the definition of health and raised the possibility that we are not destined to decline. With highly focused healing frequencies, we can reach and sustain optimum health.

The AMI 500

The AMI 500 therapeutic sound instrument is a highly effective, handheld device for use in the super-oxygenation of the cells, improved dental health, clearing of the body’s toxins and generating vital energy for women and men. By applying the device using our new “Three Point System,” an energy grid is created in the body, which continues long after the sound session is complete. The three specific device placements for each channel access the body’s own messaging system for optimum results.

Success with AMI Devices

These thermal images are from a pilot study. Participants engaged in a six-week Cymatherapy protocol using the AMI 750 in one 30-minute session per day. The scans show the results of the participant’s reduction in inflammation in the torso, oral cavity and underarm area.

What health and wellness benefits do the AMI Devices offer?

We can introduce you to a world of sound possibilities found in the AMI devices for comprehensive health. Let’s hear from some of our private owners and health practitioners who are experiencing vibrant health:

What People Are Saying About the AMI 850

“I know a lot of people who are having a hard time sleeping. It seems like all the stress from the last couple of years has taken a toll on everyone. I could not believe the deep sleep I was able to experience after one session on the new Sound Sleep Channel on the AMI 850!” David in NY, NY

“I have been hearing from a lot of my patients that they are experiencing memory loss. I know that this can be caused by long-term stress, which many have experienced the last several years. I was part of an early study on the AMI 850 Keys To Health channels and have been thrilled at the results of the Memory and Focus channel for my patients. It brings both a calming influence and mental clarity.”  Dr. H in Augusta, GA

“For a long time, I had been experiencing low energy. It didn’t seem to matter how much I slept or if I was eating the right food. I decided to try Channel 10 of the new Keys To Health for Metabolism. After one week of using the channel at home, I began to feel like myself again. By week two, I had enough energy for the things I really enjoy doing—even after a full day’s work.” Sarah in Atlanta, GA

What People Are Saying About the AMI 500

“I felt my body responding to the movement of the AMI 500 device from point to point. It was easy to learn to use and has truly revived my energy and my mood. Totally remarkable! I look  forward to every session.” Martha from Newark, NJ

“This is the first time I have ever seen an energy healing tool that has a specific channel to increase male vitality. I have never felt better—with energy to spare. The AMI 500 makes it really easy to take care of myself.” Keith from Denver, CO

“I’m so glad there is a channel to help the lymph system. I know our health depends on helping the body release the toxicity levels we experience on a daily basis. It is amazing what the AMI 500 can do in just thirty-minutes. My brain fog is finally lifting.” Mary from Scottsdale, AZ

The AMI 750 was nominated for the Thomas Edison Award for Innovation in the Field of Science and Medicine.

The history of Cyma Technologies has always included manufacturing state-of-the-art sound therapy devices which use the original codes researched by Dr. Manners and other scientists. Our ongoing evolution of sound therapy programs and devices will always include the most fully researched combinations of these original sound healing frequencies.

Pictured below on the left is the Cyma 1000, the first device Mandara Cromwell brought to the United States when she was beginning her own Cymatherapy research. This was similar to a device used by Dr. Manners in the early research of the original cymatic therapy.

On the right, is the AMI 1000 Acoustic Meridian Intelligence device which was Dr. Cromwell’s further evolution of the Cyma 1000. Used extensively for the equine population due to the applicator which makes it easy to apply the frequencies to horses. The device requires extensive training and is available to healthcare professionals.
