Sometimes my whooshing gets so bad that I'd rather be deaf. This also helps with pain at times!!!!
( I have several family members who are deaf and I know what I am saying, I also know how bad it sounds but that whooshing is soooooo aggravating sometimes.) 
I have learned to listen to binaural beats on those days. Find some soft hard phones and do not turn it up too loud either. 
 What binaural beats are: it send two different sound frequencies through the headphones at the same time. so in one ear you would have say 30Hz and in the other ear you would have 80Hz. Your ears change that pulsation to the difference of the frequencies. if that makes any sense???!!! It really does help. 
It can help for relaxation or pain or focus. All i've ever used it for is pain and the whooshing, it has always helped.

I think I may have posted this in the wrong place.... sorry y'all!!!

I use my blackberry playing music to distract me from external sounds that drive me nuts.  it helps me calm down.  any pleasing sound to distract you ought to work.  I'm sorry your whooshing is that bad.  I just have ringing.  when I can hear it, it calms me down because it means it's quiet enough for me to hear it.  putting in earplugs works better than xanax for me, because I am so auditory hypersensitive.

I love music, I listen to music a lot. I listen with headphones when I am trying to concentrate on just about anything lol! I get distracted very easily, never use to but man now it's like I have adhd or something. Music is my healer, different genres for different moods.
