Brown noise is like white noise but has a lower, deeper quality. It gained a fervent following over the summer, picking up speed in online ADHD communities, where people made videos of their reactions to hearing it for the first time. Many said it allowed their brains to feel calm, freed from an internal monologue.” (I’m in the market for sounds that can free me from external monologues…)
