cockpit noise is  a combination of engine placement and cockpit window
design. The MD-80, for instance, is probably the quitest cockpit in the
sky. The engines are very far back, and the Douglas aircraft have a very
rounded window/cockpit design to eliminate airstream noise. The 727, even
though the engines are far back, has a much noisier cockpit due to the
sharp angles in the cokpit windscrean design. Hve also flown other various
Fokker and Boeing models, but find the MD-80 the most quiet. The 767 is
not bad, again due to rounded windows, but still a bit of engine noise. I
bekieve the 747, at high speed sounds a bit "windy"
