174 Hz Deep Sleep Frequency, Black Screen, 8 Hours, Soft Tone

Eight hours of a soft, steady 174 Hz tone, layered with a gentle 87 Hz undertone and a soft, warm background hum, on a dark black screen for sleep, rest and quiet evenings. The black screen won't light up your room, so you can leave it playing all night. The sound fades in gently at the start and fades out at the end. Use it for falling asleep, a calm night's rest, winding down after a long day, or a quiet evening at home. Play it at a low, comfortable volume. Prefer a soft glow?
