You raise your voice naturally because you are in a noisy

Really? With proper hearing protection, ear plugs and flying helmets,
my ears and mouth do not know I'm in a noisy environment. With 15+ hr
missions, I've never come back with a soar throat from raising my
voice.

And the sidetone is adjusted so you hear your voice in the headphones at
a decent level, which keeps you from shouting.

OK, just put a 'scope on it and check the modulation level. I'll bet
that it is way to low for normal voice in a glider but about right for
an airplane.

The airplane pilots I hear don't sound like they are shouting, but are
just using a normal speaking voice. Even low cost headsets have
noise-canceling mikes and good sound isolation in the ear cups, so I
would not expect pilots using them to have to speak more loudly than a
glider pilot.
