One of the most interesting aspects of the Double Coil Technology (DCT) is the range of experiences people report when sitting within the field or using one of the feedback devices.
These observations include changes in the perception of music and sound, increased visual clarity, physical sensations, relaxation, and changes in awareness.
The Field Effect
The Double Coil Technology was discovered by accident while experimenting with electromagnetic fields. The field device had been wired incorrectly, causing the magnetic fields from the coils to cancel each other out. At the time, we happened to be listening to music.
Almost immediately, something seemed different.
The music appeared more melodic, the ambience increased, and the soundstage seemed noticeably larger. Switching the coils on and off appeared to change our experience of the music.
This became one of the most commonly reported effects of the DCT field.
My own experience was one of becoming immersed in the music. Individual instruments seemed easier to distinguish, while at the same time the overall musical experience became richer and more expansive.
Another interesting observation occurred when a guitar string was plucked. With the machine switched on, the note appeared to sustain for longer.
We also began receiving reports of changes in visual perception.
One participant described the experience:
“My experience today with the machine was interesting. I did it with headphones and it was not a piece of music as usual, but a song from YouTube. With the machine off I listened to the song as always and also watched it because it had a video.
Then when I turned on the machine it was very clear to understand word by word of the song and when I watched the video I was able to observe every detail no matter how insignificant.
I definitely feel that consciousness is intensely awakened.
We verified that DCT sound tests could be carried out with headphones, additionally an interesting discovery was made in that objects in a video had more clarity.”
This also demonstrated that the DCT sound experiments could be carried out using headphones rather than conventional speakers.
The Feedback Coil
Similar changes in the perception of music have been reported when using the feedback coil.
Physical sensations are also commonly experienced.
A recurring observation is tingling in the hands or feet, depending upon whether the device is connected to foot plates or handheld electrodes. Some people describe a mild sensation similar to static electricity.
More pronounced physical responses have occasionally been reported, including shaking of the body.
The following testimonials illustrate some of the wider experiences people have described.
Testimonial — S.v.D.
“I’ve tried it out just now (for about 10 minutes), and I’d like to share my observations so far:
To start, the area in my chest/lungs instantly felt more spacious – like there’s more room to breathe. Also, my breath feels richer when I use the Dongle.
My mind also feels more spacious! Using the Dongle has a really calming effect on my thoughts. It’s not like I’m thinking less, it feels more like my ‘mind space’ increases in size, making the ‘room my thoughts occupy’ relatively (much) smaller (if that makes sense). Overall, it makes my mind clear and calm.
Moreover, this effect is very noticeable in my perception of sound. A noisey area for me can be very overwhelming. This feels to me like all those sounds combine together in a big wave of nonsensical noise, leading to sensory overwhelm. Using the Dongle however, it feels like my mind has more room to ‘hold’ all these different sounds, maintaining a clear overview of what I’m hearing without drowning in all the noise.
So overall, I experience more spaciousness (in a variety of ways) when I use the Dongle”

“I’ve updated the machine with pure copper plates (99.99%) and this feels quite different than the aluminium foil that I’ve used previously. The feeling/sensation is more electrical in nature ……
…. During my first session I felt the enegy moving through my body and the places of some previous injuries were highlighted to my awareness. Then I felt a pleasant current of energy, electrical in nature and also strong activation of the crown chakra. It also enhanced hearing of the Sound current, which I usually hear in a meditation on Light and Sound. After the session I felt relaxed and refreshed with a greater sense of calmness.”
Testimonial — A.H. and G.H.
“We used to coil before bedtime and experienced a better nights sleep.”
Concluding Notes
The accumulated experiences indicate that the Double Coil Technology produces effects that people can perceive in a variety of ways.
Some experiences appear repeatedly — particularly changes in the perception of sound, increased spaciousness or clarity, physical sensations, and relaxation — while others are more individual.
These observations make the DCT an intriguing area for further exploration. Because the machines are relatively inexpensive to construct, the next stage is to investigate these effects more systematically and develop clear protocols for their use.
