Noises to relax to.

White noise contains all frequencies at equal intensity. Pink noise emphasizes lower frequencies and sounds more balanced to the human ear. Brown noise (red noise) focuses on the lowest frequencies, sounds like a deep rumble, and works well for sleep.

Most people use noise for 30–60 minute sessions while sleeping or working. You can safely use it throughout the night or for extended focus sessions. Take breaks if you feel habituated.

Yes. Brown and pink noise are particularly popular for sleep because they mask disruptive sounds without being too stimulating. Many people find they fall asleep faster with a consistent noise background.

Keep it comfortable: loud enough to mask ambient sounds, but not so loud that it becomes distracting. Night Safe mode automatically limits loudness and softens bright-spectrum noises.

No. Unlike binaural beats, noise does not require stereo separation and works perfectly fine through speakers or regular headphones.

Night Safe limits the maximum volume and gently reduces bright-spectrum noises (white, blue, violet) to prevent sudden loud spikes at night. It is ideal for use while sleeping.

Yes. Many people play noise as a background layer while listening to binaural beats or music. Keep the noise at a lower volume so it does not mask the other audio.

Noise is random audio energy across frequencies used for masking and background calm. Isochronic tones are evenly spaced pulses designed specifically for brainwave entrainment. They serve different purposes.
