Going about 50 mph tonigh I decided to roll down the rear windows to let some air in but still be able to hear the podcast I was listening to. With the windows fully down I heard this weird noise like there were subwoofers pressed against my ears. It only took less than a second to convince me to never do that again. Here I am about an hour later and my ears still ache.

When you roll down the rear windows in a sedan at highway speeds you might hear what sounds like a helicopter hovering above your car.

That's exactly what it sounded like. I'd never experienced that in my old mazda 6 so it was a big surprise.

Cavity Resonance

When you roll down one window, you create a cavity resonance. Just crack another window or sunroof and it'll reduce the resonance.

Yea I counter this by opening the passenger side window just a bit and sometimes my own. I have always heard this in small cars so knew what to expect

It happens in most cars, it's called wind buffeting. Just open the windows a bit. On convertibles they offer the wind screen tha sits behind the seats.
