I had h in one ear last Sept lasting for 3 months.... It can go away! Listen to rain sounds every day for about 20 mins a day, it's apparently rich for the brain. Mine went as fast as it came on. The ear with h in felt open, like no ear drum in there shielding me from sound. So I do believe it can go. Don't be too regimented in protecting from sound unless it's sound that you have to raise your voice to be heard. Wish my t would go the same way as that came on too! :-(
