a sound wave's amplitude is a measure of how loud it is. the frequency of the wave is the sound's pitch. is it thus correct to say that pitch is determined by how quickly the sound is gets quiter and louder??

Pitch is more complicated than frequency. It's the difference between harmonics.

start screaming at different loudnessess
your pitch doesn't change, only volume

high pressure (and low pressure) does not equal loud. what equals loud is the vibration, or the difference between the pressures, or the amplitude. if you increased the density of all the air, you don't just start hearing a loud noise out of nowhere, because the air is still.

also this is an 18+ board

when you double the pitch you end up octave higher
sounds travel speed is determined by which materia it travels through
also +-6db means doubeling or halving the distance for same amount of noise

Pitch is the number of times the signal moves up and down given a specific interval. Volume is how far up and down that signal moves.

Sound and electromagnetic waves have a hidden property beyond amplitude and frequency.

Not her but, when considering a graph of a sound wave, when people refer to the amplitude, is that that the maximum height of the wave? So a constant property? Or, given a sound wave f(t) = sin(t), does the amplitude oscillate as t increases?

OP said "how quickly." In high volume, the pitch is determined how quickly the sound gets quiter and louder in high steps, whereas in low volume it's the same but with low steps. I think that's what OP meant.

So what? OP's argument is still valid. In high volume, the pitch is determined by how quickly the sound gets quiter and louder with high steps (high amplitudes), whereas in low volume it's the same but with low steps.

No. that's quite simply not how human audio perception works. Why do you think you can't ignore a crying baby? Also, learn about decibels
Amplitude and Loudness are not interchangeable and as such the pitch is not the result of changes in loudness, but often changes in pitch can change perception of loudness.

Isn't all sound simply just changes in loudness in different frequencies and volumes?

pressure is loudness.
vibration speed is pitch.
hope this helps OP

pressures and pitches, but yes fundamentally.
not in the way you're describing.
you can mimic infra-sonics by rapidly transforming a wave forms amplitude.
often known as FM modulation/synthesis.
but that's not how natural sounds are actually generated.
much like you will never encounter a 2khz square wave in nature.

Why the fuck would you ask that when I explicitly said no it isn't!?
The answer is simply: ABSOLUTELY NOT

what are some unusual waves that one wouldn't expect to find in nature that actually exist?
this probably sounds silly but after reading about the first explorers to encounter an electric eel for the first time, becoming completely perplexed by an animal generating electricity, reading about such unusual discoveries brings me joy and amusement
