깊은 브라운 노이즈

Brown noise with the highs filtered away, leaving an even lower, muffled rumble with almost no hiss. For listeners who want the deepest possible background.

수면、깊은 이완、소음 차폐

Synthesized by Sleep Island as a seamless 3-minute loop.

The web player loops the current preview audio. Choose a timer from 15 minutes to 2 hours, or keep it looping; timed playback fades out gently. The timer sets your listening session, not the original track length.
