I don't have any sources but if I remember correctly, some people on Tinnitus Talk said so. In my own experience it is so as well, although it is difficult to empirically trace a direct link between the two. Health experts typically claim that if you experience tinnitus symptoms after a loud event such as a concert, it indicates that your hearing has been damaged on some level. Ergo, I 'd figure if you experience a worsening of your tinnitus symptoms after exposure to sound, even though that sound might be quieter than dB thresholds commonly marked as 'dangerous', it is an indication that that sound has been too loud for your ears, in one way or another. Not an expert by any means, but this is just my 2cts.
In my opinion, things only start to improve over time if you take measures the prevent aggravating your hearing. Just continuing your life as usual and hoping it will go away will probably not work.
