I wonder if you could use a smart phone to control the volume.
I have noise reduction headphones that are very good when flying. It blocks out the engine noise and crying babies to a major extent. And I get to listen to my book.
I wonder if there is an app that would allow me to listen to the live event at a volume that is comfortable to me.
Here's an app that is for snooping in on conversations. That's not for me. But with noise reduction headphones maybe it might work work where it's too loud or too quiet like in a concert hall.

ps I didn't read the entire thread. If someone else suggested this idea already, sorry.
