Old-school ITT Cortelco 2500 (desk) or 2554 (wall) set.

Replace microphone element with noise-canceling microphone.  Best one is 
Roanwell Confidencer available from Mike Sandman, Graybar, etc.  Also 
good is Walker - Clarity NoiseCensor or Allen-Tel GB117 (available from 
Graybar).

For exceptionally loud areas, an amplified handset such as Allen-Tel 
GBG6M-44 as well.

The noise-canceling microphone is the key.  It will help you be heard at 
the other end and kill the noise in the sidetone to you.  Works wonders. 
   The 2500 desk phone has a dual-gong mechanical ringer, loud and 
distinctive.  2554 wall model is single gong, still fairly loud.

Google for suppliers of these items if you aren't near a Graybar.
