Doesn't block all noise
It does an ok job, I have to run a fan at the same time and that does the trick for us. I still hear my husband snoring (ughhh) but i do not hear noise from the street, such as cars or firetrucks passing by. I used to use the fan alone and that didn't cut it so adding the sound machine has helped but I was hoping I would no longer need the fan. It will do for now. Not the best for me.
