I'm wondering if there is a common opinion on microphone placement for measurements.
For simplicity, let assume we're measuring at one point only being the main listening position and frequency range > 150hz.
Obvious choices I see are:
1. Next to the ear measuring speaker on the same side - the downside I see is that in reality the head prevents reflections from the other side to reach the mic thus altering the real picture. There is indeed a measurement difference between when I sit there and when I don't sit there.
2. At the nose point - didn't measure, but theoretically there should be the same effect from the head blocking reflections from the rear of the sphere
3. At the center of the head
And another thing - in the last 2 situations above, should the mic point to the corresponding speaker or should it point straight?
