Yes, I should probably mark my sarcasm a bit more clearly - my rhetorical point here is not that Amir should do this, but rather that "compensating" a 5128 measurement cannot transform it into a 45CA measurement. Different pinnae and different headphones interact in novel ways, and attempting to...

I have deja vu all over again! I decided to respond to this one by making a publicly viewable google sheet - please feel free to "make a copy" if you feel inclined to play with it. If I recall Sean's presentation correctly, shortly after that slide should be one about the adapted Harman target...

Quite literally - and as i said there - that is an assurance I was offering to you that even if you fundamentally mistrusted us, you could have a conversation with us on good faith without any fear that, even if we were maliciously motivated, we would be able to misuse it in any way. I offered...

Ah, what the hay, I'm in this thread still (but no promises about replying further) - in the spirit of intellectual charity, I present the impact of volume size on transfer level with a constant displacement probe: from Brüel & Rasmussen's seminal text on ear sims. As you can see, volume itself...

I am returning to this thread solely to note that this is objectively not what was said at any point, and that i have very clearly and directly stated that I offered it to be recorded so that you could be absolutely certain it would be impossible to misrepresent you. In that same post, I once...

I will say this again, if you understand the actual causes of variation in ear Z, you will see that it is by no means likely that excluding subjects has biased the trends of the ear Z here - there are a finite number of mechanisms of error, and their traits are pretty obvious in the data. Søren...

Okay, so perhaps we should take a step back here and ask if you understand why ear load Z changes and what changes it - the insertion depth/volumetric modes, of course, shift as a product of the actual length of the canal (terminated at the IEM/earmold/etc on one end, and the drum on the other...

For Olive to have 5000 people in his listening tests, or for Søren to leave out some people from his MRI cohort? In both cases, the answer is fundamentally "resources are finite and limited, and science has to make do". In the case of the paper on ear Z, the only reason that the extra 12 people...

This is essentially an equivalent argument to that which could be made against the use of head and torso simulators over omnidirection microphone capsules for measuring headphones in 2013. It would have been about equally uncompelling to me then as well - the Harman work is exceedingly good...

Then we're in concert there - I'm always a bit worried when people talk about measurements as a basis for EQ, because I've seen a lot of folks trying to nail jello to the wall with AutoEQ, but as a starting/jumping-off point I get ya completely. Right, so this one is an area where I think that...

I have no idea of whether there is a statement I, or Headphones.com, or whomever you're indicting here can make to dispel this idea, but I'm going to try anyway: No, what I want people to think is that the 5128 is more accurate in its approximation of human ear impedance. This is because the...

It would surprise me immensely if Crin stopped measuring things on his IEC711 - he has never said he plans to do this, and mentioned the cost of maintaining and updating two separate databases as part of why his patreon tier pricing changed a bit (not that he needed that justification). I think...

The point is not moot because @crinacle and @Resolve's warnings about such cross-comparison apply also to a measurement of IEMs conducted with the KB500x or KB501x pinnae - this would include, as far as I am aware, @amirm's measurements of IEMs. Again, measurements seated in an...

It's a shame that so few companies follow the advice from Factors That Influence Listeners' Preferred Bass and Treble Levels in Headphones' conclusion

This generally agrees with my understanding of Sean's take on Lorho's findings: to some extent, "less treble" and "more bass" seem to be substitutes, albeit imperfect substitutes.

You'll have to pardon the dual reply, I didn't see your edit. To some extent, the 5128 not being more accurate in Sean's test there is a tautology - the only respect where it is demonstrably more accurate is in ear Z, and those tests were blocked canal, which, necessarily, cancels any effect of...

Except that it...isn't, as a generalization, which is what I was responding to. It's true that some 60318-4/711 configurations give greater precision in insertion depth, but that's not the case with the anthropometric ear canals, and indeed more true-to-life fitting was part of GRAS' sales pitch...

Spirited discussion here it seems - it's a long holiday weekend in the land of freedom, so you'll pardon me if I refrain from working too hard in my replies. Re "pluralist nonsense" - glad we waited out Pride for that framing - we're referring consistently to Segmentation of Listeners Based on...

Perhaps I should have said "practicing electrical engineer"- the note I was aiming to hit there was fairly identical to what I understand to be your official (and quite reasonable) statement on the matter: "Furthermore, anyone with any technical background reading his contributions and mine see...

Unfortunately, the news is that there is no news yet - we're working on a bunch of projects simultaneously, and this one isn't top priority at least until next month.
