Earplug is a nice addition to the set. Just because.
Even gloves wouldn’t be necessary, but I liked the “full gear experience”.
I am only jealous because I didn't think to protective glasses and, as said, earplugs.
What is a “gum shot”

This is when a bubble inflated with
bubble gum bursts. That's what a “gum shot” is.

For some people, they may not need earplugs, especially those who are used to sounds such as factory machines or others.
For the record: nobody "gets used to" loud noise. Hearing damage collects over the years, and every exposure to loud sound adds up. It might take years before you realize it's too late.
In fact, every exposure to sound destroys the “ears,” the resource of which differs from person to person. In the presence of congenital defects and abnormalities, the destruction process occurs faster. Wait, what are we discussing? We're not on a medical forum.
Does the sound of metal hitting metal when engraving text on a plate cause unpleasant sensations and discomfort? Then use instead of a hammer, for example, a wooden mallet or something similar ("rubber" mallet). Also, in a small and enclosed room the unpleasant effect will be felt more.
"Soft" metals, such as aluminum, if used as seed phrase plates, will ring less when struck. This is just a note.
