sign language
Anyone can learn sign language, but sign language is mostly associated with deaf and hard of hearing people which is their native language. (Although quite a few don't know sign language and learned language via oralism method.)
You study and practice it, just like when learning any other language.
An interpreter for the deaf is called a sign language interpreter. They help facilitate communication between people who use sign language and those who do not.
Study and practice. Or you can find a teacher on line or see if your school has a sign language program.
