I've found B767 cockpit noise levels to be the lowest of any aircraft
I've flown.  Although I have never flown a B737, when visiting the
flight deck, the noise level did seem high.

Mind you a B747 flight deck isn't that quiet either.

Does anybody have any noise readings for various types of airliner?
Are there certification standards for noise levels in cockpits?  It
would be interesting to make comparisons.
