About this listen

This 90-minutes black noise audio provides a deep, minimal sound environment with very low perceived intensity.

Black noise is commonly used to reduce sensory overload, block intrusive background sounds, and support deep relaxation and sleep.


The added 136.1 Hz frequency is softly integrated into the noise. It is not intended to be heard as a tone, but felt subtly as a calming vibration beneath the noise layer.


Ideal for deep sleep, stress relief, meditation, sensory reset, tinnitus masking, and ASMR background listening.


Use headphones or speakers at a low, comfortable volume. Disable bass boost or audio enhancements for the cleanest experience.
