With headphones off, how much wind noise is there in the cockpit at 530 mph? (Subjective question, I know.)

Consider that most airline pilots wear the headsets with small speakers similiar to your Stereo headphones. It doesn't seem like they would be able to do that if it were loud.

I've been in a CJ-2 and it was pretty quiet. There was some wind noise but you could hold a conversation. The EMB-170 I jump seated on was quiet too. I've heard that the ERJ is pretty loud, especially at lower altitudes. This, as I'm told, is because the nose is pretty much right off the Brasillia and wasn't designed for the speed. I'm sure EMBQA or somebody that knows the junglejets will be able to elaborate or prove me wrong.

The B737NGs with Removal of Eyebrow Windows & Installation of Vortex Generators near Windshield is supposed to Help reduce Noise Inside the Cockpit.

It depends on the particular a/c. The 727 was VERY loud. At altitudes below 300 it was louder yet. Some pilots opted to by expensive noise cancelling headsets. The DC-10 and MD-11 a very quiet comparitively speaking. Above 10,000ft we usually take off the headsets and just use the overhead speakers.

DC-9 was very quiet, much less noise than a Boeing. MD-80 is all but silent up front, typically the headsets come off as soon as it is legal to do so.

Airbus products were pretty quiet. Headsets off, it is easy to have a conversation back and forth across the cockpit.

Of course I grew up on multi recips and helicopters. Most planes seem quiet after that.

737NG - Little noisy...comparable to anyhwere else in the cabin in front of the wings. Quiet enough, however, for conversation and for the radios to be heard through the overhead speakers.

Supposedly the 737 classics are quieter up front than the NG.

Back in the days when one could go into the cockpit while inflight, I remember stepping into an anoyingly loud MD-83 cockpit to take a picture. Back down the aisle it was much quieter. BTW, that day I had the chance to witness Elmo's Fire all over the center window! Pretty amazing sight.

DC10--loudest noise was from the airconditioning.
MD80--relatively quiet, loudest noise was the instrumentation cooling fan.
B757--slightly more noise than MD80, but not much.
B767--slightly louder than B757, mostly airflow from airconditioning.
MD90--Dang quiet...they got rid of the cooling fan noise.
F100--quietest airliner I've flown. You only knew the engines were running by looking at the guages!
B738--noisiest airliner I've flown (can't recall my two trips in 727s). Earplugs are the norm with many pilots trying lightweight ANR headsets (I've tried two, but neither worked well). And yes, the noise is outside wind.

The ERJ is quite loud once you accelerate into the 300+ knot range. We wear david clarks (our company provides two of these in the cockpit of every aircraft) or other full size headsets. I have seen some people wearing smaller headsets, but I'd imagine the noise would get annoying. We may be the only jet pilots that do this, and yes, it is because we have essentially the same fuselage construction as the EMB-120.

Is the B738 cockpit more Noiser than the B734.
Why
Would the Elimination of #4R,4L,5R,5L windows & installation of Vortex Generators before 1R,1L Windshield help reduce it to below the B734.

I'm interested to know why the 737-800 is louder than the -400. Is it because of the greater collection of electronics that need additional cooling? Or is there something else I'm not thinking of?

The Mad Dog is damn quiet up front, as AAR90 said, you mostly hear the cooling fans. On rotation, you almost have to look at the engine inst. to make sure that they're still running!

73NG was relatively noisey up front, at least compared to the 'dog. I agree with everyone's statements on this one, surprising considering it's such a newer jet.

AAR90, anything must be quieter than that old Hummer huh?  Smile

I know nothing about any other version of the 737, but the -800 equipment cooling is almost silent. You have to listen for it specifically in order to hear it. The STBY ALT Vibrator is louder than any internal airflow. External airflow is another matter entirely.

It'd be a toss-up. The 738 wind noise is a lot higher pitched and therefore more difficult to reduce than the Hawkeye's low propeller "hummm." Then again the energy draining vibrations aren't an issue for the 738 either.  Wink

The CRJ is very quiet up front...especially up in the 30's its easy to have a conversation up front. The loudest noise is the air conditioning. Down low if we are doing 330 knots it's a bit louder from the wind, but not too bad. A couple guys wear david-clarks...for what reason I dont know...most wear the Telex 750 headsets like or molded single ear devices.

Most probably it is because it flies faster than the older brother.

From own experience..

B727-100QF Really loud
B757-200PF Noisy ( airconditioning noise ), I only know the cargo version , maybe the pax version is more silent
B767-200SF Really silent, headset not necessary

During flight I often visited the cockpit of a Swissair/Swiss MD11 and A332 (before 9/11). Both were very quiet.

Hi HAWK21M.

An danish airline called Star Air flying parcels on behalf of UPS.

All B757 was leased from UPS and right now we have only one left.

DHL only have 1 or 2 -200PF the rest is as far as I know -200SF

Greetings,
PW2040


25 Jetlagged : Faster aircraft = higher air flow speed around the windows = more noise. Given the same window configuration, noise will be louder the faster you fly
26 HAWK21M : BD which is part of DHL now,will be getting Three B757SF around May 2006.The first time in the Country. How Mx friendly are they. regds MEL
27 PW2040 : Hi HAWK21M. As far as I know they are very Mx friendly...............there are very seldom any problems. VH PW2040
28 HAWK21M : Thats great news.Whats the preffered version B752PF or B752SF & which is the better Engine P&W or RR. regds MEL
29 PW2040 : Hi Hawk. B752PF is the freighter off the production line at Boeing and B752SF is the converted pax to cargo........majority is still the production on
30 HAWK21M : RB211s are supposed to be more thrust generative & Mx friendly,whats the percentage of units produced via-a-vis the P&W if you are aware. 70%. regds
31 PW2040 : HI Hawk21M It is actually 80% according to Rolls Royce homepage. Yeah I know the PW version is not that common , but a positive thing at least what I
