Same issue I mentioned in my comment! There's a constant battle happening between the audio engineers and the noise floor of the the venue. It surprisingly doesn't take too much more db to be heard above the crowd, like in a perfect world, if the crowd is sitting at 90db then 95db would be ideal. But unfortunately a crowd's loudness ebs and flows and that can easily get drowned out so most just default to 100db and embrace the inevitable tinnitus. I recommend everyone invest in Earasers or something of that quality so y'all can appreciate music safely without losing all of the dynamics.
I'm taking live sound classes at my community college right now and we talked about this yesterday. The biggest issue with a large venue packed with people is the noise floor is very high. For instance if the crowd is 90db, then you've only got 10-20db of headroom to work with. 90db is already enough to cause hearing damage after 8 hours, and it gets exponentially worse with just a few db more, by 100 you can only safely be in that for 2 hours and that is generally the ideal loudness for that kind of venue. Of course since the engineers probably have hearing loss, they tend to raise it even higher to 110 which is loud enough to still cause damage over time even with regular earbuds unfortunately. So unless you can have a quiet crowd there is nothing you can do about needing ear protection, I recommend hanging by the engineer booth because they tend to be just far enough away to comfortably hear everything around 90db because they generally can't use earbuds while actively mixing.
Random unrelated thought I just had, can you guys think of any interesting musical applications to a laser microphone? I found this super cool video when I tried to look it up (there's practically nothing)
A Kora! It's an African instrument that is considered a guitar harp, with 21 strings ranging from the size of bass guitar string to fishing wire. The way it is played allows you to play the bass, lead, and rhythm at the same time. Here is a short example of a master kora player Toumani Diabate showcasing the instrument: https://youtu.be/8luhdxS2KuM?si=llpa2YVyIOf77_Nd
As a guitarist I found this guy who transcribed Toumani's work onto a classical guitar, very interesting listen https://m.youtube.com/watch?v=55QnOlXckOk
My other thing would be trippy out there instruments that seem to put you in a different state of mind like the Yaybahar or "The Beam" that the grateful dead likes to break out sometimes
