(PhysOrg.com) -- Air travelers have long complained of the blandness of airline food, but new research suggests the aircraft noise may be the problem rather than the chefs or the menu.
If you've ever experienced the exceptionally powerful and reverberating sounds of a jet during takeoff, you likely won't be surprised that the noise produced by jet engines is ranked among the loudest of human-generated noises.
