To add on to this, noise reducing earplugs are also a thing - search for "concert earplugs" or something like that.
Using them I was able to watch Godzilla in a movie theater without constantly wincing as well as go to a concert at a bar and actually have a decent time. Highly recommend for general use, I carry them everywhere now.
Kids open their mouths when their heads are upside down - great way to quickly investigate what exactly they're chewing on
