Would you leave your job?

I work in an office, I love my job, however, it's an open plan office. This means I can hear everyone. I find it really hard to concentrate on my job when everyone is on the phones talking. Not only that but one person in particular always talks extremely loud, and their voice actually grates on me. When they laugh/cackle it makes my skin crawl like finger nails down a chalkboard.
The rest of the team are extremely loud but not as annoying.

Because of this I find myself on edge, anxious and slightly angry, whilst also feeling a bit depressed. As soon as I leave the place I am fine. I don't want to leave because I love my job, but being around that one person is soul destroying. What would you do?
