Its a machine i got at Brookstone. It plays diff sounds to help u sleep. One is called "white noise". I also have it as an app on phone for wen i travel

Absolutely. I've had it from the start and have always understood it's a symptom of MS. Mine can be really distracting but I guess most of the time I'm able to ignore it.

I also have non stop ringing in my ears. My doc says there is nothing that can be done about it. The one thing that does help me is a white noise machine when i sleep. Somehow it kinda cancels the ringing out for awhile

Mine sounds like several Crickets. Its not annoying and comes and goes.

Yes I have had that and now I feel my hearing is oversensitive loud noises bother me a lot more than before.
