Say Alice decided to orbit dangerously close to a couple of black holes circling each other. She is in a heavily enclosed astronaut suit, as is Bob, who is floating much further away.
Assuming Alice cannot hear anything from any other source, would she be able to hear the black holes due to the gravitational waves travelling through the air in her suit? We'll assume Alice is a tough girl so she isn't getting ripped to shreds.
If the answer to the first question is yes, and assuming that the waves are still strong enough for Bob to hear them, would the sound he hears differ in frequency?
If the answer to the first question is yes, would changing the polarization of the gravitational wave affect the sound?
My formal physics knowledge is limited to high school, although I have some outside experience through sites like these and Youtube. I'd appreciate if answers could be kept to an undergraduate level or lower.
Thanks for the help!
