The noise is continuous, natural, and always unique. 7 SOUND TYPES - Brown Noise — deep, rumbling, perfect for sleep - Pink Noise — balanced and warm - White Noise — classic, even coverage - Rain — gentle rainfall - Wind — soft breeze - Ocean — rolling waves - Cafe — ambient coffee shop chatter MIX YOUR OWN BLEND Layer any combination of sounds and adjust individual volumes to create your perfect mix.
