"Anything that will block out sound will work. Some kind of earplug, or just something to go over them. It is hard to get an appreciation for how loud these things are without firing one for yourself. The reason I am as persistent as I am about it is that you can lose your hearing if you're unlucky, or worse. Some people get this constant ringing in their ear; I've experienced it before myself. And for races that don't regenerate like mine, I've heard it can even be permanent. Just see if you can find something in the storeroom along with the ammo, or I'll have to prove to you that I'm serious about just using my hands." Tarentek explained with a smile.
