Answer 3

YES ! !

(if a deaf man farts in his living room, does it make a sound?)

Answer 4

Depends on your definition of sound. The air sure vibrated. If sound includes what animals hear, then yes. If you strangely restrict it to human hearing, then no.

Answer 5

When you close the refrigerator door does the light go off?  How do you know for sure?
