An interesting read, explains a lot about how we perceive sounds differently. I have read more than a few data sheets from parts manufacturers, but not so much about ourselves.

Each of us create our own references. The machines that convey an event must be objective - thats why data sheet still matters.

My take on Linkwitz's take on this is that we are able to perceive the audio illusion created by stereo speakers because we have learned over time to create a three dimensional audio world, ie, we have learned how to hear and when we hear sound reproduced in an accurate enough way we instinctively "fill in the gaps" because we know what it should sound like.
We are all in agreement about how brains are different, but this paper describes how the topography of ones head will guide sound in a different ways, contributing to different perceptions.
So you didn't actually read it then...

Right, it makes perfect sense, just haven't seen anything that called it out with actual testing before.
Pretty cool.
So the future of extreme diy tweaking may include a 3D scanner to quantify your head shape!

except for gross defects though our brains continuously rewire, accommodate to 'normalize' the subjective experience as the neural pulse trains being sent to the brain are modified by our organic transducers, external ear, head physical dimensions
at least to the degree that there is any common experience - for which we have such audio relevant evidence as music creation and listening
or the statistics for perceptual modeling lossy codecs quality, large fraction of the population rating better tunings, higher rates "transparent" on all but a few % of hand picked "killer samples"

Ha ha. This reminds me, some people think it's a good idea to correct for the Fletcher Munson curve, when it isn't.
My personal gross defect is chronic tinnitus, I'm still waiting for my brains plasticity to normalize.......
Interesting look at HRTF. Figuring it out from a scan.
Some friends on this forum have tested the Smyth Realizer headphone device, that takes your HRTF into account by acoustic measurement. Their comments when listening to sound processed for the HRTF of someone else? "You have weird ears."
We do hear differently.

Our outer ear produces a relatively radical eq curve with a 10-15dB boost at some frequencies. Exactly where and how much depends on the ear shape.
This also the reason headphones do not and should not have a linear FR and why some people find manufacturer A's phones unuseable but manufacturer B's near perfect while others have the exact opposite preference. They are both right but the model used by A might more closely resemble their pinna and vice versa.
The exception would be phones for binaural (dummy head) recordings because the pinna eq is already recorded.

I have even read of some people claiming that wearing specs affects their sound perception.
I can believe that might be the case with owls ....

Very likely. The arms of the specs contacting your skull like the instrument they use during a hearing test
I read recently that some research showed that wine tastes different depending on which hand you pick up the glass with... good grief... 🙄
Makes no odds to me, I don't use a glass 😀

Hey Pano, we will be spending some time in the Leesburg area over the next couple of winters. I have a Smyth Realizer maybe we could get together and play with it.
Interesting Dan. I thoroughly respect the various unconventional viewpoints you have expressed over many threads I have perused.
Fortunately I am currently not optically challenged and am therefore unqualified to make a personal appraisal of this claim.
I therefore propose to carry out a listening test using a pair of Rayban Wayfarers. I just hope the Koolness Kwotient involved does not bias my findings.
Scott, you bet! I was very miffed I didn't get the chance to hear the demo at Stuart's house. I'd love to take you up on the offer.
