hearies don't fart in public, occasianally it happens of course, and yes we can hear em. and yes its a huge embarrassment that the person usually tries to pass it off as someone else(which NEVER works) or they leave the area immediately.
and no, you can't tell the different between a male and female fart, they sound the same.
theres differnet kinds...theres silent ones, loud ones, ones that sound wet...one that sound like a helicopter is flying over head...ones that sound like the air being let out of a baloon...ones that sound like a high pitched whistle.....
