Brown Noise for Focus, Study & ADHD | 10 Hours Black Screen

10 hours of brown noise on a black screen, for focus, studying and sleep. FOR PARENTS — PLEASE READ Keep the volume well below 50 dB, about as quiet as a soft conversation, and put the speaker at least 7 feet (2 m) from the cot — never inside it. If you cannot comfortably talk over it from that distance, it is too loud. Use the lowest volume that works. Consider switching it off once your baby is asleep rather than running it all night. Phone and tablet speakers can be louder than a dedicated sound machine at the same slider position, so check with a decibel-meter app rather than trusting the slider. Guidance from the American Academy of Pediatrics and Hugh et al., Pediatrics, 2014. No talking, no music, no interruptions. The screen stays black so it will not light up a dark room. Use it for: deep focus · studying · ADHD focus · falling asleep · tinnitus relief This sound was generated with sound-synthesis software. Nothing is copied from other videos.
