My psychologist specialized in hearing issues just adviced to stop avoidance behaviour and there is no reason to avoid loud places if I use hearing protection. This maybe works best for people who don't have reactive T that doesn't get louder after loud noise
For me going to loud places means more messed up hearing despite of earplugs: muffled hearing, everything sounds quieter like my hearing is worse for even weeks, reactive T reacts, hyperacusis symptoms get somewhat worse for a moment etc.
