Flying may become a more serene experience for those traveling on the new 737 NG Boeing Business Jet.

Sound pressure levels dropped an average of 8 to 12 decibels for N1 engine tones. That's significant, especially when you consider that decibels are logarithms of sound levels. Now, if only someone could do something about those screaming babies.
