What is pink noise, and how is it different from white noise? Pink noise contains a mix of sound frequencies, but the lower frequencies are more prominent. This gives it a softer, deeper sound that can feel less sharp than white noise. For some families, pink noise can help create a steady sleep environment by softening sudden household sounds during naps or bedtime. The Nodiee Sleep Assist Smart PRO includes pink noise, white noise, brown noise and other calming sounds, so you can try different options and see what suits your bub’s routine best. Keep the machine at least 1 metre away from bub’s sleep space and use a safe, comfortable volume. Which sound works best in your home? #babysleep #pinknoise #whitenoise #sleepmachine
