All good info. I’m now retired, but what I did for a living was record sound and vibration for Ford Motor Company. My equipment for sound usually was an Aachen Head by Head Acoustics. This device looks like a human head and shoulders and has a mic in each ear. This is a global recognized company that most all auto manufacturers use. The Aachen Head usually is placed in the front passenger seat. The data is recorded and analyzed. And of coarse listened to with high quality electrostatic headphones. Head Acoustics also has the in-ear mics. So, I’m very familiar with binaural recordings, great stuff! Nice to see this brought up.

Great info. I have always been tempted to try electrostatic headphones.

Here's what it looks like, minus the fixture. As you've experienced, once you listen to binaural recordings there's nothing else like it, hard to explain.

Brief description from their website.

"The artificial head geometry offers you:

a mathematically describable reproduction of the human head and shoulder geometry with an award-winning design

an accurate reproduction of all acoustically relevant parts of the human outer ear

Turn it on - Record - Done!

The HEAD Measurement System IV is a stand-alone, mobile measuring device that is ready to perform aurally accurate binaural recordings immediately after powering up.

The recordings can be saved directly to a CompactFlash card, allowing stand-alone operation without a notebook or PC. Via the integrated headphone output, the recordings can be played back immediately with aurally accurate equalization."

Artificial head measurement systems like the HMS IV are compatible with conventional measurement technology and are necessary for an authentic hearing impression during playback.
