Pink noise sounds deeper and softer than traditional white noise because it places more emphasis on lower frequencies. That steady background sound can help soften sudden household noises, like doors closing, footsteps or conversations, which may otherwise interrupt bub’s sleep environment. The Nodiee Smart PRO includes pink noise among its 34 soothing sounds, making it easy to find the sound that best suits your baby sleep routine. Keep the volume at a safe, comfortable level and place the machine at least one metre from bub’s place of rest. Click the link in bio to shop.
