In the past 20 years since I developed mild T I have gone to many clubs and concerts (not terribly loud ones mind you) using 22 dB silicone ear plugs. 15 years ago went to some dance clubs (~90-95 dB ?) nearly every weekend each summer for a few years. 10 years ago attended concerts (~100 dB ?) a couple of times each summer. I never perceived any spikes in T all this time. Of course I've had one recently, though an ENT says it is unlikely related to my time in a loud place with protection.
A cautious approach might involve the following: Take a good look at tables which show loudness for different noise sources like chain saw, concerts, etc. Get an idea of typical dB levels. Perhaps buy a good noise meter and carry it with you along with some really good ear plugs, say over 30 dB attenuation. After you've recovered from this spike, and assuming you do, start with very brief exposures with the hearing protection and see how it goes. There are always risks, so the safest approach is to avoid any place with noise level greater than say 75 dB.
Just my 2 cents...
