Your response is very helpful to me.
Complexity is not an issue when it comes to learning.
If we can derive the correct results, we should endure it. Haha

1. In the case of dynamic microphones, I think impedance measurement will be easier than other types of microphones due to the connection between pin 2 and pin 3.
2. Balanced active microphone - This is the result I'm currently trying to achieve.
?
In a situation where two pins have opposite polarity but supply the signal equally,
I'm wondering whether the output impedance should be defined as the impedance between pin 2 and pin 3,
or the impedance between the output going out of pin 2 and ground.
?
From my personal perspective, when thinking about output, I believe the latter is correct.
?
However, as Jerry mentioned, I can't rule out the possibility that it might be the impedance between pin 2 and pin 3.
?
But then again, I think there might be about a 2-fold difference between the former and the latter (in the case of balanced active microphones).
There's a lot of information about sensitivity, frequency response, and polar patterns when it comes to microphone measurements.
However, I couldn't find definitive information about impedance measurement.
?
I'm really curious about what method microphone manufacturers are using to measure the impedance values they provide.
?
thanks Scott
