12 Hours of Deep Black Noise for Sleep

12 hours of Deep Black Noise - the darkest, lowest, most enveloping sound in the noise spectrum. Engineered for listeners who want the closest possible experience to absolute silence, without silence itself.

Deep Black Noise takes standard black noise further, filtering out nearly all mid-range and pushing the remaining sound into sub-bass and ultra-low frequencies - the kind you feel more than hear. Listeners often compare it to the rumble inside an airplane cabin or the deep hum of a ship's engine room felt through the hull. It's the auditory equivalent of weighted blanket therapy.

This deep black noise sleep sound is ideal for: severe insomnia and sleep onset difficulties; sound sensitivity, misophonia, and hyperacusis; tinnitus masking (especially high-frequency tinnitus); trauma-informed and anxiety-disrupted sleep; blocking neighbor sounds, HVAC hum, and low-frequency traffic; deep meditation and breathwork; and listeners who've outgrown white or brown noise and want the deepest, most enveloping option in the spectrum.

Trusted by over 1,000,000 listeners worldwide, weekly episodes feature sleep sounds created to mask disruptive noise, calm the nervous system, and promote deep relaxation.

Our library includes a wide variety of sleep sounds such as white noise, brown noise, pink noise, green noise, black noise, nature soundscapes, and more. All episodes feature smooth, consistent audio and no sudden changes that could disrupt your rest.

Sweet dreams 😴
