Hello. I'm new here. I've been reading through this sub for a bit and I'm curious how many people here actually use sound as part of their biohacking experiments. Something that's bothered me for quite some time is how quickly everything gets grouped under "relaxing music." A Spotify sleep playlist, pink noise, a binaural beat, an isochronic pulse and a generated session built around a particular frequency/rhythm are not really the same experiment.

Even if they all sound relaxing. I've been testing short audio sessions and looking at the physiological response before/after rather than just asking "did I like it?"

Sometimes the session that feels nicest isn't necessarily the one producing the more interesting change. And sometimes a session seems to do very little because the starting state was already completely different. I'm curious how others here test sound.

Do you go purely by how you feel afterwards, or are you measuring anything alongside it?

Built a 10-hour AC brown noise track — here's what I learned about why AC sounds work differently than fan sounds

The main difference is the mechanical character. A fan has a consistent rotational frequency. An AC has more irregular low-frequency content — compressor cycles, airflow variations — which is closer to brown noise in character.
I built a track that tries to replicate this: brown noise as the base, AC hum on top, low room tone, and a steady ambient frequency underneath. Black screen format, 10 hours.

Curious if anyone here has noticed a difference between fan and AC sounds for sleep.

Hey everyone 🤍

I made a new ASMR video for anyone who's had a stressful or exhausting week. I wanted it to feel like someone is actually taking care of you and helping you release the tension from your back and shoulders.

It uses slow hand movements, gentle massage sounds and wooden massage tools.

Hope it helps someone relax tonight. 💤

Synthesizer frequencies processed to bring out those golden waves of warm tones for relaxation, meditation, healing and enjoyment.

About the synthesis, I used Native instruments Absynth 5 for its amazing control over hz incrimentation.

I use 2 or 3 oscillators that are routed each to their own LFO with the duty to diminish the vol gently over a specified time and to do so over again in cycles.

Other functions for each were given to the LFOs, depending on what suited each OSC best.

The result gives an audible sense of movement and direction.

Korshamn, about 35 km east of central Stockholm, Sweden, on the edge of the Stockholm Archipelago. This spot faces Nämdöfjärden, where the more sheltered inner archipelago begins to open up toward the Baltic Sea. To get to this spot, you actually have to walk through a huge fenced grazing area where cows roam freely. One of my favorite places!
