Ringing Ears

I am a 19 year old male who attended a concert on dec 19 which was fri night. Once I got to the concert I realized i had forgotten my ear plugs and it was too late to head back and get them. The concert was extremely loud and I knew i was going to pay with ringing ears. I have only been to one other concert where my ears rang but it went after about a day. The day after the concert the ringing was still pretty persistent but my hearing was not muffled. The second day the ringing had went down a lot and my hearing is 100%. I was having a pretty positive attitude after the first day thinking that upon waking up on the third day that all would be good. But when I woke up I still had very faint ringing in both ears. I have not had any pain in my ears and all of my hearing is completely there and normal. Will this ringing eventually die out? Is it taking longer because of how loud the show was and how long it was as well ( I was there for 4 hours)? I dont notice the ringing when doing everyday activity. I only do when I am sleeping or in a very very quiet room. I am hoping that this will eventually fade out but I am seeking some good advice.

Again, the ringing has become very very faint after two days but is still noticeable when sleeping or in quiet areas. Thanks again!
