If loud voices are bothersome, you may have recruitment as well as tinnitus. Recruitment, or hyperacusis, is when a sharp loud sound is amplified so that it's far louder than reality. Loud noises/speech shouldn't make tinnitus worse; in fact, tinnitus is generally nature's way of giving you something to listen to--when you are listening, you are often totally unaware of tinnitus. It's usually most bothersome in very quiet settings, like when you're trying to fall asleep. A thorough hearing test will tell if you have recruitment.
