White noise (as a listening genre) consists of broadband, non-periodic sound with equal energy per frequency, presented as long-form recordings or streams for masking, sleep, focus, and relaxation. While the signal-processing concept dates to early 20th‑century acoustics and radio, the musical/consumer genre emerged with dedicated LPs and tape releases that marketed neutral, steady noise as a functional audio environment. In modern platforms it spans continuous single-tone textures (true white), filtered variants (pink, brown, blue), and blended layers (HVAC hum, fan, airliner cabin), typically delivered as hours-long tracks without discernable musical form. Listeners use it to mask environmental sound, aid sleep hygiene, increase concentration, or create an anonymous, calming sonic bed that doesn’t demand attention.
