16 SOUNDS, ONE TAP Tap a tile and play instantly. Built-in sounds include: • White — balanced, full-spectrum hiss • Pink — softer, deeper, like steady rainfall • Brown — warm, low rumble, like distant surf • Grey — tuned to equal-loudness, the way your ears actually hear • Infra — deep sub-bass rumble • Ultra — bright high-frequency air • Focus — shaped to mask nearby speech • Lull — warm mid resonance for winding down • Eight precise band-limited tones — 60 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz and 8 kHz — for targeted masking and sound therapy
