Noise induced tinnitus which is what I believe you have, will usually improve with time. It can take up to 2 years for a person to fully habituate to their tinnitus and it can happen sooner. What is of vital importance is that you try not to do anything that will cause it to increase. The danger is, your tinnitus will most probably improve in the weeks and months ahead. After a while you will get so used to it you may not even hear it. Then, you might make the mistake that so many people have done with this type of tinnitus which is noise induced. They return to using headphones or go to places where loud music is playing, then they find the tinnitus returns with a vengeance and is a lot louder than before.
If you listen to my advice and follow it the chances are you will make a full recovery and your tinnitus will reduce to very low levels or in some cases completely go. Now, the advice: Please do not use headphones or a headset even at low volume. If you have to use them in class, keep the volume as low as possible and if you can don't use earbuds.
A member of this forum had completely habituated to her tinnitus for 6 years. Her tinnitus was originally caused by headphones. She was able to go to work and was enjoying life to the full. Last year just before Christmas as it is now, she contacted me, saying she returned to using headphones after 6 years. She kept the volume low, and within one week, the tinnitus returned and was much louder. The last I heard she is unable to work because of the distress of the tinnitus.
Be careful that is all I'm saying to you. If you go out to clubs or concerts then use Noise reducing earplugs. Keep in mind, even wearing earplugs you are not completely safe. If the sound is too loud it will pass through your head and be transferred to your inner ear by bone conduction and spike the tinnitus. This can make it increase to a louder and permanent level. I am not saying you must stay in and not go out and enjoy yourself, but you need to be careful of loud sounds and headphones. If you follow my advice I don't think you will have any problems and you will get better and be able to do everything that you want to within reason.
Best of luck, please read my posts in the links that I have sent you.
