I do prefer 'stone deaf'; stones may be mute, but they are warm in the sun, they feel soothing in the palm. It is a piece of the earth, attached to God. I do not know what the pedants mean when they write 'profoundly deaf' to describe the person who has never heard a sound. Deaf is deaf and silence is forever.
