I attended aDoobie Bros Concert a few months back in Nashville. I forgot my foam buds, so put tissue in my ears. I measured a SPL of 106 db! They played great, but way too loud.
Unfortunately, this is all too common and sad from an avid concertgoer's perspective. I love the musical attack of a live event, but some of the shows I've been to are just stupidly loud. I took one of my kids to an outdoor concert event in downtown Boston where the artist included Julien Baker (younger artists and fans...) and her show had peaks in the 130dBC range! You could feel the sound waves 'popping' my clothes. Even with earplugs I had ear discomfort for two weeks and then my tinnitus jumped up in volume (likely permanently).
Wearing earplugs definitely help, but they don't cover shows like that. When one looks at how the NRR rating works, it is not as simple as subtracting your earplugs NRR rating off of your concert levels. e.g. https://www.sensear.com/blog/how-do-you-calculate-a-noise-reduction-rating-nrr
(NRR-7)/2 for many of the common earplugs I use (e.g. Etymotic Research, Loop Earplugs) give you only (20-7)/2 = ~ 7dB reduction. When the shows are in the 100+ range that is still very problematic...
Having said all of that, my only regrets are not starting to wear earplugs in my teens at shows (vs my 30s). I still would not give up the many awesome experiences I've enjoyed at the live concerts I've attended over the decades. At least my hearing will have been very well used and thoroughly enjoyed when I get put to rest :)
