Pink Noise Sound Machine (12 Hours)

Download our Mobile App! iOS | Android --- Our tried and true Pink Noise, beloved by 10's of millions of people around the world! Pink Noise is a combination of White Noise and Brown Noise. They are overlaid on top of one another to gain the benefits of both the higher frequencies typically used more for sound cancellation, and the lower frequencies which tend to be more soothing for sensitive ears. Its soothing, calming, constant tones are wonderful for helping adults and babies alike to fall and stay asleep, for study, for meditation, for managing anxiety, or for any other activities where you want to block out the world and focus solely on the task at hand. It also has incredible sound masking properties for use in distracting and noisy environments! *If you have been enjoying this Sound Machine up until now, don't fret that you see this new episode published with a more recent date! It's the same exact Sound Machine that you and millions of others have been 💤 to for years. I just republished it so that it would be at the top of the feed and remain more visible for new folks just finding the podcast! 🗣️
