White Noise is incredibly effective at canceling out sounds you don’t want to hear…period. There is a heavier emphasis on high-end frequencies that can counteract incoming sounds and drown out the most insistent of external interruptions. My White Noise listeners may be my most passionately addicted 😄. People use this Sound Machine for all sorts of applications, but it’s the gold standard when it comes to sound cancellation. Its 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.
