This morning I was thinking about ways to block out extraneous sounds while working at my cubicle. I thought I might be able to get some headphones from the office supply closet, and I looked online for software that would generate white noise. I ended up downloading and installing a program called Tinnitus Masker Pro 2.1 ("Tinnitus Masker Pro allows you to choose from 14 different sounds and change their parameters so you can achieve the best masking effect for your tinnitus symptoms. Tinnitus Masker Pro is extremely easy to use and get to grips with, yet versatile enough to cover a wide variety of tinnitus symptoms."), which I couldn't get to actually work -- I uninstalled it after a few minutes.
Just a few minutes ago, two coworkers a couple cubicles away were talking about their hearing... both of them suffer from tinnitus. They compared stories about how they acquired the condition and discussed remedies.
