White Noise (Equal Energy)

Has equal energy across all audible frequencies (20Hz to 20,000Hz). Sounds like a steady radio static or fan. Great for blocking out sharp sudden office noises.

Pink Noise (-3dB / Octave)

Dampens higher frequencies to mirror organic nature sounds like steady rainfall, rustling leaves, and wind. Proven to enhance slow-wave sleep and memory retention.

Brown Noise (-6dB / Octave)

Features heavy, deep bass resonance resembling distant thunder, ocean surf, or low airplane rumble. Highly recommended for ADHD focus and deep relaxation.
