Our headband uses auditory (acoustic) simulation. But we are VERY different from elemind.

If you look at the research behind elemind, it is clear they designed a study to show a positive result. Somnee, less so, but it is only a single paper.

It's interesting to me you used "sound waves" to describe acoustic stimulation, which is exactly NOT what we are doing, or how auditory stimulation work (in our case).

A "slow wave" aka delta waves is the measure of the synchronous firing of neurons which is the hallmark of deep sleep and the foundation of health. It is the activity of the brain pumping the glymphatic system, which is clearing metabolic waste, and is linked to immune function, hormone response, parasympathetic response, and more.

Our EEG headband is detecting these slow-waves (the firing of neurons), and when we detect this brain activity, at a precise point in this synchronous firing, we interrupt the brain, with a brief pulse of sound. In response to this interruption, the brain goes "hey, this is vital to my health, don't mess with me right now", and increases the synchronous firing of neurons, both in that slow wave, as well as following up with another slow-wave after, sometimes 2, even 3, rarely 4 (but it is person dependent).

A slow-wave only lasts for 0.8-1.2 seconds, so this timing is very precise, and we can see the change in brain activity immediately. We stimulate in a 5 on/ 5 off protocol, so we can see the change in brain activity within seconds. We are not comparing different nights, as we know sleep is different across nights. The response is very consistent.

If you read the research from elemind and somnee, they sound very similar, with a huge red flag. They both say "we stimulate near the peak of an alpha wave, and then you fall asleep". There is no measure of a change in the brain activity. Just alpha wave, stimulation, sleep.

I can go on and on about all the red flags, but you can read about elemind here - https://neurotechnology.substack.com/p/avoiding-neurotechs-t...

I found the Somnee headband unbearably uncomfortable, and it didn't do anything for me.

You mention acoustic stimulation as "sound waves" and that's where I wanted to clarify the whole "listen to a 120hz sound and it will improve XYZ".

As far as I am aware, all of this sound waves stuff and interacting with brain waves at certain frequencies is nonsense. A brain wave is a human construct for how we visualize the electrical activity of the brain, just like an EKG is a visualization of electrical activity of the heart.

You'd never say "we're interacting with your heart wave at this frequency", right?

I have many bug-bears with the industry as a whole, and it is a bit terrifying to me that I'm working in this space surrounded by so much nonsense.

We don't fund studies. The scientific principles of what we are doing has been known for about 10 years now. But it is difficult to do, and Philips have a TON of patents around this space - they fund a lot of the research.

However, we support researchers who are already looking into this space because we have the best technology (well, waiting to be proven but we have advanced beyond the protocols of Philips and Dreem).

I hope that helps understand where we're at, and maybe how we differ. I'm happy to answer any more questions.
