ok simply put why do airbus engines have that horrible whining sound to them?? and if i am not mistaken dont some boeings use the same engines but without the sound, i dont know what causes it but, with summer fast approaching the red eye flight business has risen here at bristol and as it doesnt have a closing time we are getting flights in 24 hours a day. but the thing is i have to keep my window open as my room turns into a sauna even at night, which mean i am getting woken up every 15 minutes these days.
so can someone please help me understand what causes that awful sound which keeps me awake most the night
Thank you
