Can A Graph show IEM Soundstage: maybe so!

I think thats pretty correct, except something about an actual notch centered at 10k simulates normal hearing since there is a phase cancellation in the outer ear parts.

What is interesting to me is, would it be possible to have a good amount of treble with said notch. Maybe a really tight Q factor notch right at 10k and then back up to 'normal' neutral treble.

Sony already figured this out with the IER-Z1R. The key is their use of a DD super-tweeter to get the upper treble past the 10 kHz notch just right to create a proper sense of outwards center image projection.

Personally, I like to simulate a similar notch with PEQ to give my AKG closed-backs out-of-head soundstage, dipping the upper mids a bit as well for greater width.

Sorry, can you elaborate more on what Sony did with Z1R to get such an impressive soundstage? Because Z1R doesn't have a 10k dip at all (https://squig.link/?share=Super_Review_Target,Sony_IER-Z1R), yet I've heard that it has a very large soundstage.

Those graphs are smoothed to the point you might not be able to see the 10k notch actually. On the other hand I could just be totally wrong.

You can actually set the smoothing parameter. I tried 0, and it still doesn't have a 10k dip.

It's an interesting theory, and of course we need more data to see how it holds up, but so far I wouldn't say you're totally wrong!

Hi, what an interesting thread! I used the formula for the ZEX pro, I got 21. However the ZP has a very 'squished' in your head soundstage to me.

Hello.
I can't measure it exactly.
Could you tell me the approximate value of the 3D Tripowin Olina, Ikko Oh10 and the Tea mk1.

Thank you!
