We do this all the time. Those that live next to a busy railway line or under the flight path at an airport hardly notice the very same sounds that their visitors find intolerable. Live with a dripping tap long enough and it becomes unnoticed. Accept that those tinnitus sounds are there to stay. Understand that they will not cause any physical harm. Turn attention towards that which is positive. Those sounds will then move to the back of consciousness. They are going to be here but we do have the option to not hear.
