Whisper by Chrissie Keighery
From Waterstones: Fifteen-year-old Demi's world is shattered when she is left profoundly deaf by a sudden illness. Everything is different now, and Demi must learn to adapt to a new school, new friends and even learn a whole new language. Whisper is a coming-of-age tale, about discovering who you are and where you fit in life. About friendships and first love and, more of all, learning to love the person you are.
Sounds really good! And it has some amazing reviews on goodreads:D
