What's buzzing during A319 takeoff?
As a passenger in an A319, I hear a loud low-frequency buzzing sound during takeoff and climb. There is also a little bit of wind noise, and faint engine whine, but this buzzing is much louder. What is it?
It sounds as if it comes from up front and is kind of like the noise from a motorscooter engine or 50/60 Hz audio hum, but more raspy. As the plane levels off and picks up speed, the buzzing goes away and the wind noise becomes much louder.
Maybe I'm not asking the question correctly. Anyway, thank you for considering my question.
