Silicone? Sounds like my jerry-rigged echo measurement rig.

Not fully suited for headphone measurement, because the pinna is just sculpted, not real, and the silicone has not been treated with "skinner" additive, so is a bit too dense.
I'll post the fancy pic of that half-head for echo thingy later - it also had to shape air through mouth.
(Insert silicone sex joke here  )
How does it work? You placed it on a speaker, calibrated via REW to flatter frequency response if needed (it boosted lows like a real mouth and face), put a cellphone on a proper stand or mount, put measurement microphone at Reference Point and you got your echoey recording. Generally got -35 dB echo from that, much more than free air.

I'm very slowly making one based on my own actual pinna and ear canals. Partly done - ear canals exist and work, pinnae negatives exist (positives do not yet), cheek simulator does not either.

Now I'm imagining putting measurement mics inside a ReallDoll's head and writing it off on your taxes as an expense for your headphone measuring website/business.

After all, it's very important to simulate the acoustic effects of hair, shoulders, and of course breasts, on open headphones...

How would you measure the simulated acoustic effects when filing your taxes?

"This paper file has acoustic properties and effects when hit by sound waves produced by my open headphones. Dear IRS, please explain how this furthers your ability to perform checks and collections? I hereby offer my services to measure the acoustic effects in ..."

Almost like testing what yelling at a screen has for effect while listening to Sepultura through your open headphones. Then recommend headphones and Amp-DACs for therapeutic purposes...

Vibro Labs Veritas is on pre-order, and they insists that it is IEC 60318-4 compatible coupler. But it's only 79$, so I'm not sure it is real.

Hey guys, I had to change the way I was wording things, it wasn't really clear. Vibro Veritas is not IEC 60318-4 compliant, I just used the documentation for the IEC spec when designing this low-cost coupler... and speakerphone, this is the coupler I was emailing you about a few months ago! Hope that clears things up!

omg That was you? I never knew that...
why did you sold your coupler as if it's IEC compliant? You shouldn't have advertised like that.
