I have had sleepless nights myself.
That is where the sound-making started.
This article is not an explainer.
It is a production note about a track I actually made.
The subject is the one I am most attached to among everything I have published:
“174Hz + 396Hz + 432Hz | Triple Solfeggio Sleep Stack + Delta Binaural + Brown Noise” (6 hours 12 minutes).
Why those three. What was hard.
I will write down what worked and what did not.
Why I layered 174, 396 and 432Hz
When I build a sound for sleep, I start from the low end.
The reason is simple: the higher the frequency, the more it stings the ear.
It defeats the purpose if a sound meant for sleeping tires your ears out.
So for anything aimed at deep sleep, I design from the bottom up.
The three have different characters.
- 174Hz — the lowest foundation. The direction the body sinks toward
- 396Hz — the letting-go layer. For putting down the tension of the day
- 432Hz — the layer that wraps everything softly. Without it the whole thing turns rigid
On top of that I layer delta binaural beats and brown noise.
I chose brown noise because white noise carries a hissy high end that catches the ear.
Something browner, with a thicker low end, suits the night better.
Let me be honest here.
There is no proven medical effect for these frequencies.
I did not layer them “because they work.” I layered them because, after searching, this was the combination that felt good to my own ears.
Struggle 1: Keeping high frequencies soft without losing them
This is where most of the time went.
As you go higher, there is always a band that starts to hurt.
But if you simply cut the highs, the sound dies and turns into a muffled lump.
“Soft, and yet the frequency is genuinely present.”
Reaching that state is the hardest part.
In my process, I check by ear every time whether anything is stinging around 2–5kHz.
When layering, I avoid putting multiple sounds in the same band.
Give each one its own space and they stay audible without raising the volume.
Thickness, and gentleness. Holding both is the goal.
Struggle 2: The loop seam
Long-form tracks have a problem you cannot avoid.
The break where it loops.
Six or eight hours is obviously not played in one take.
A repeat happens somewhere.
If that joint clicks, or the phase shifts and the sound thins out,
someone who was drifting off wakes up right there.
The sound must not break. For sleep material this may matter more than fidelity itself.
Struggle 3: Stray noise
Unintended sounds creep in while working.
Small artifacts from processing,
grit born from reverb turning muddy,
fine beating where layered tones interfere.
You do not notice them at normal volume in daylight, but at night, in a quiet room, at low volume, they are audible.
That is exactly how sleep tracks get listened to. So I listen again, and again.
Honestly, this is still not fully solved. I have noticed problems after publishing and rebuilt tracks.
The difficulty of recreating a singing bowl
Another ongoing pursuit is the sound of the singing bowl.
What makes it hard is that you cannot reach that resonance by simply adding harmonics.
A real bowl has metal vibrating in complex ways, beating against itself as it decays.
Stack perfect integer harmonics and it comes out too clean — which reads as fake.
Break it up too much and it is just muddy.
I am still working out that balance.
Without change, no one can keep listening
The other thing I keep in mind is change.
When the same sound continues unchanged, people either get bored or, oddly, tense up.
So I bring in several frequencies and slowly shifting layers, aiming for a state where
“something is always changing, just below the level you would notice.”
Accents are placed far away.
Anything sounding right at your ear becomes a sound that interrupts sleep.
What can and cannot be said about this track
What I can say
- It is designed around the low end so it does not sting the ears
- It is adjusted to flow for hours without breaking
- I made it for myself, for nights when I could not sleep
What I cannot say
- I cannot say this sound will make you sleep
- I cannot say the frequencies themselves have medical effects
- How it feels varies from person to person
Sound may be one part of an environment that helps sleep. Beyond that, I will honestly write “I do not know.”
Listen for yourself
At the volume of something sounding far away, on a night you cannot sleep.
That, I think, is the right way to hear this one.
I will keep leaving records like this for the things I make.
Including the parts that did not go well.
