I agree with the advice AnthonyMcDonald has given you.
Since you have had tinnitus for many years and it has now increased, you need to be very careful not to make it worse. The truth of the matter is, loud sound and noise induced tinnitus, which is what you have, do not go well together. Some people believe wearing earplugs will prevent this type of tinnitus from getting worse from external sounds but unfortunately, this is not the case.
If external sound is loud enough it will pass through the head and transfer to the inner ear by bone conduction which can spike the tinnitus. If you are fortunate the spike might be temporary and the tinnitus will reduce to its previous baseline level.
However, the spike could increase the tinnitus to a new permanent level - in addition to this there is the risk of developing variable tinnitus. This condition mostly affects people that already have noise induced tinnitus and habituated to it for a year or more and suddenly the tinnitus has spiked. The spike or series of them are usually caused by further noise exposure that has irritated the auditory system. Listening to audio through headphones, earbuds or headsets even at low volume can cause it too.
Please be aware variable tinnitus is usually a more severe form of noise induced tinnitus and can be especially difficult to habituate to. Sorry to sound so sobering but you need to be very careful about what you're doing regarding exposure to loud sounds.

A person with tinnitus that wears earplugs while asleep is not a good idea for many reasons. Please go to my started threads and read the following post where more is explained about this: New to Tinnitus, What to Do?

I wish you well,
