we can't even get our own IT dept to run bids correctly for a month. It may take a bit before we get to it.

Mgt just calls it the "Whine out on the Line".

Ops Check Good!
 
Our older Boeings (300's/500's especially) are quite noisy and that is probably why we are in the habit of wearing our headsets all flight. Our newer ones, especially the 800's are much quieter. I may have to try taking it off next time.
They're not. I would advise against it.
 
A 738 at cruise altitude/Mach is about as loud as a 757 at 250kts. In other words, you can take off the head set at cruise and no big deal. It's the climbing and descending into/ out of low altitudes where it's loud. The newer 738s have little vortex generators just below the front windows that supposedly reduce wind noise (they don't)... also, getting rid of the eyebrow windows didn't help either. Let's face it, keeping the original 707 cockpit window layout = a loud design.

Yup, it's loud. I've not been on the 757 but I do know that on the 737 when I put on a noise reduction headset at cruise I can turn the volume knobs down about one third.
 
I wear earplugs the entire time the engines are running. I can hear the other guy fine 95% of the time. May look stupid but looks better than a hearing aid in 20 years.

Does the hanging mic work as the boom?
