My wife can hear me mutter under my breath three rooms away and on different floors, but a car noise - total deafness. If it starts when she turns the key - no problems there. I'm 50-60% deaf in my right ear and 25% in the left (thanks, US Army), but a car noise to me - it's like a ricer with booming bass.
