Interesting project. Here's a thought which I've always had in the back of my mind, ever since I saw something similar in an episode of Buck Rogers (70s-80s)! Many people struggle with falling asleep due to persistent beta waves; natural theta predominance is needed but often delayed. Imagine an "INEXPENSIVE" smart sleep mask that facilitates sleep onset by inducing brain wave transitions from beta (wakeful, high-frequency) to alpha (8-13 Hz, relaxed) and then theta (4-8 Hz, stage 1 light sleep) via non-invasive stimulation. A solution could be a comfortable eye mask with integrated headphones (unintrusive) and EEG sensors. It could use binaural beats or similar audio stimulation to "inject" alpha/theta frequencies externally, guiding the brain to a tipping point for abrupt sleep onset. Sensors would detect current waves; app-controlled audio ramps from alpha-inducing beats to theta, ensuring natural predominance. If it could be designed, it could accelerate sleep transition, improve quality, non-pharmacological.
So are the brain waves the cause or the effect?
Are beta waves a sign that my mind is racing and wide awake, or are they the reason?
Don't know but as AI advances, questions like that may get easier to answer.
What’s your proposed mechanism for how audio waves would induce brain waves?
That's a toughie, but if it were me and I had the energy, I'd start by looking at the following patents:

No idea about audio frequencies close to hearing, but I'm pretty sure it's common to manipulate the brain with ultrasonic frequencies these days.
Yeah, I'm sure that technology has existed for decades. Common folks just not allowed to know about it. It's "for our own good!" sarcastically speaking :(
