AutoEQ through PEQ: fitting to a person

[Branislav]

I have an idea: AutoEQ, while not final solution for every problem is a good starting point. But one obvious thing is missing: personalisation.

What if a shoe maker makes perfect ergonomic shoe, and proceed to manufacture it in one size only? 

If we have a headphone measurement made on a standard head, and have correction for it, we omit differences in ear canal (and the rest) size differences. What could be done?

Below PEQ settings You can put a nice slider which can multiply every frequency from PEQ bands in use by a constant, that can be +/- changed by moving a slider left-right. Since peaks and dips frequencies depend on ear chambers dimensions, all of them can be proportionally moved up/down until they fit users ears. It can be (probably) adjusted by hearing...

To me, it doesn't look overly complicated, almost only UI addition: all used frequencies times coeficient, maybe +/- 20%  (from 0.8 to 1.2), or something, resonant frequencies should be compared to varying ear-canal dimensions to get useful span...

 

Than You for a nice working PEQ. For me it is a most useful form of EQ.

Basically a "strength" control that adjusts how strongly a m existing set of EQ parameters are applied.

Hello!

Not the strenght, but the frequencies. They are changing according to ear canal dimensions. Strenght can remain the same.

How would changing the frequencies help? That would create a completely different profile which would no longer compensate for the specific idiosyncrasies of the named headset.

You got a point. Maybe. To a degree...

Every peak and dip in measurement is a result of a system cosisting of a sound source and a ear chamber. The measurements are not result of a headphones alone, but the the whole system.

Put earphone in a bigger ear, and all peak/dip frequenccies are going down. And vice versa. I understood (maybe incorectly) that measurement of a phones response is a big problem because we cannot take phones alone, and they actually do not work in regular usage alone, without added ear "box".  And that box varies in size. So the frequency response. We know the physical rules, how frequencies of resonance change, when box changes its size.

It's just my presumption...
