Pink noise, as a music/utility genre, consists of long-form recordings of 1/f noise whose power decreases by ~3 dB per octave, yielding roughly equal energy per octave. Compared with white noise, it sounds smoother and less hissy, with a deeper, more natural tonal balance that many listeners find easier on the ears over extended periods. As a streaming category it functions primarily as "purpose-built audio" for sleep, focus, tinnitus masking, privacy, and mindfulness. Releases are typically hours long, loopable, and minimally varying, sometimes subtly modulated to prevent ear fatigue. Producers may leave the signal pure or blend it gently with environmental textures (e.g., light rain or fan hum) while avoiding melody and rhythm so the sound remains non-distracting.
