บราวน์นอยส์

Brown noise concentrates its energy in the low end, a deep, rumbling sound like distant surf or an airplane cabin. Free to play online, looping seamlessly.

Sleep、Focus、Noise Masking

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.
