1 Hz Delta Pulse (12 Hours) – BLACK SCREEN • Deep Sleep, Calm, Zone Out

Sink into the 1 Hz Delta Pulse and let everything slow to a crawl.
This video plays a continuous 1 Hz low-frequency signal for 12 hours on a completely black screen – no music, no melody, no visuals. Just an ultra-slow infrasonic pulse running quietly in the background.

In EEG research, around 1 Hz sits deep inside the delta brainwave range (roughly 0.5–4 Hz), often studied in connection with very slow brain activity and deep sleep. This audio is an external sound wave, not a brainwave, and it does not claim to change your EEG or provide any medical or psychological effect – it’s simply a very low-frequency signal plus a dark screen.

You can use this 1 Hz track for:

A barely-there ambient layer while you rest, meditate or zone out

Experimental ultra-low-frequency testing for your audio setup (if it can even reach 1 Hz)

A dark, distraction-free background for sleep or deep relaxation routines

Personal sound experiments with slow infrasonic pulses

What’s inside:

Duration: 12 hours (12:00:00) continuous playback

Audio: single 1 Hz low-frequency tone / pulse at a constant level

Visual: full black screen – no motion, no flashing, OLED-friendly

How to listen (important):

Start at VERY low volume – ultra-low frequencies can stress speakers if pushed too hard.

Increase slowly until you reach a comfortable level; never drive your system at the limit.

Avoid listening at high volume for long periods – protect your ears and your gear.

Do not use headphones at high levels, and never while driving or operating machinery.

If this 1 Hz delta pulse fits your sleep, chill or sound-experiment sessions, add it to your playlist and return whenever you want to drop back into the extreme low end.
