 Well, I know a number of people who will not or cannot go to crowded restaurants because at that point they say the tinnitus is overwhelming for them. Explain that to me. So sometimes what happens is the tinnitus for them is so loud that it interferes with speech. And there's a lot of patients where the louder the noise, the louder the tinnitus. So the tinnitus kind of chases the noise. So it's one of those that we just kind of manage a little bit differently and we don't want people to ever stop living their life. So for those patients, treatment is really essential.
