Who is deaf from AC DC?

Excuse me, but could you please clarify your question regarding the band AC/DC? Are you asking who in the band AC/DC is deaf, or perhaps you're making a reference to a member of the band that has faced hearing challenges or a specific song or lyric that mentions deafness? As far as I'm aware, none of the members of AC/DC are deaf, but if there's a specific context or meaning behind your question, I'd be happy to explore it further with you.
