Wouldnt you want a microphone that emilates a persons ears? They have these dummy heads that have testing microhpnes in them for headphone testing i would think somthign similar to this would be ideal/ Even if its just 2 microphones in mono.

Not really. Everyone hears slightly differently. If only because everyone's had different events in their lives that have damaged or not their hearing accordingly. If the idea is, first and foremost, accuracy, you want the test equipment to be as neutral as possible. Ears, are anything but.

It sounds like you're wandering (unintentionally) towards the old loudness switches, that tried to contour the FR to mimic the the equal loudness curves... not necessarily a bad goal, but not exactly easy to implement...
