Push-to-talk is a common way of dealing with this, but there is
another known as the "confidencer". It is a special network that
eliminates sidetone so that noise entering through the mouthpiece
won't be heard in the earpiece. Yet another method is to obtain a
"noise cancelling" mouthpiece. These are relatively easy to find to
fit the standard (pre "K" style) handsets.

The brain filters it out. It is very amusing to watch people in a
noisy location jamming a finger in the opposite ear. That technique
does little good when the real problem is noise entering through the
mouthpiece. At one of my transmitter sites, there is a standard phone
that I have been too lazy to modify. When making calls in the noisy
room, covering my other ear has virtually no effect on
intelligibility, but cupping my hand over the mouthpiece makes all the
difference in the world.
