Does the munson curve also apply exactly the same to stereo sounds when it comes to an even balance related to the human ear volume wise? If not, what's the difference?

It boils down to timing differences between left & right. We cannot really sense direction on very low & very high frequencies, and it's really difficult on sounds without transients.
Yes, people that are deaf in one ear have the same Fletcher-Munson curve. It's measured for each ear in isolation.Brandon203113 wrote: ↑Tue Apr 09, 2019 11:38 am Does the munson curve also apply exactly the same to stereo sounds when it comes to an even balance related to the human ear volume wise?

We are the KVR collective. Resistance is futile. You will be assimilated.

Okay that makes a lot of sense, i feel dumb for asking now, after posting i'm realizing some of these stereo plugins i have arent affecting the mono so it's basically adding volume to stuff, i was wondering why it was getting way louder...

You need to keep in mind something you rarely if ever see mentioned about audio perception: level perception is non-linear due to the compression that takes place even before encoding and transmission on the cochlear (auditory) nerve. We'd probably need to look into detailed studies that describe the function of the nerve fibers connected to the hairs inside the spiral organ to understand exactly how the compression is effected and whether it introduces (and how if not) non-linear artifacts such as side-bands or harmonics.

In other words while you can definitely hear an isolated tone through a wide range of amplitudes this is not the case with multiple tones or noise masks. With noise masking, some of the rules about data entropy apply where each 6.02 dB of amplitude above the noise floor provides 1 bit of data entropy.
tl;dr: The real range of relative amplitude sensitivity is closer to 40 dB (1/100th), but it's frequency dependent and a bit complicated. This doesn't have a whole lot to do with stereo perception which seems to be timing-based. Studies that attempt to break down the systems involved reveal a lot of complexity, so there is plenty to learn for those so inclined to research.
