Please take a look at these:
Someone is deaf/mute (Is this one offensive or not?)
Someone is a deaf/mute(I know this one is offensive)
So is there a non-offensive way of call people who are deaf/mute?

No, you can't say that someone is a deaf. 'Deaf' is not a noun.
You can say that someone is deaf, but unless they can hear nothing at all, it's not completely true, hence the need for quantifiers - "He's a bit deaf; He's almost completely deaf" etc.
The politically correct usage where I live is hearing-impaired.
