Hearing protection

[bktheirregular]

Picked up a set of earplugs today, to try and blot out the never-ending high-volume nerve-grating yammering in the adjacent office that's been going on hour after hour, day after day, for something like five weeks now. Bear in mind, these are the same sort of earplugs that served well for attenuating the noise of a military rifle range.

But the yammering next door is still getting through and breaking my concentration.

At what point do I start wondering if the problem's something with me?
