ICU White Noise Machine provides 3-sound settings and 6-light modes with 3-brightness levels to set the mood for restful sleep, concentration, or relaxation. This multi-function white noise machine generates sounds to mask annoying noises that can interfere with falling asleep or staying asleep. During the day these same sounds can help drown out distracting noise for better concentration and facilitate a calming space for yoga and meditation. This white noise machine is compact and lightweight, perfect for your bedside table, or desk, and can travel with you wherever you need to relax. Before use, remove the protective clear film that covers the top of the machine.
