Wankels have a sound profile that is more irritating to most ears.
That is until you drive/fly one long enough, then everything else
sounds irritating.

People refer to my relatively open exhaust RX-7 as the "angry bee"

That's funny Hans.  When I first flew my plane over the house, my wife
said it sounded like an angry mosquito.

My plane must really be loud. People in town can hear me fly over from
inside their house when I'm at 4500 feet.

Al Wick heard me fly over his house in Portland when I was at 12,500
feet (I gave him no advance warning).  It's just a very distinctive sound.
