Just a distraction
After reading all the rave reviews, I thought this would be the solution to living in the apartment below two young children who are constantly running on their hardwood floors above me.  This machine does NOT block the sound.  It masks it a bit by giving the mind something else to focus on, but I can definitely still hear the noise.  I am very disappointed in this product.  It doesn't block outside noise either--I could still hear the leaf blowers loud and clear.
