Was Earhart's microphone even able to pick up Noonan's voice?

Marty, I could not find the one I was looking for but here are a couple of examples of vintage microphone types.

The first is a WW2 military type that was widely used. According to the caption that was with this one, it is a special type for use in ground stations with little background noise. The almost identical, noise cancelling type for aircraft, only had 3 small holes in the center of the mic instead of the 7 larger ones shown here. This was described as the way to distinguish the ground type from the more widely used aircraft type. These mics had a raised edge all around the mouth piece that could be used to place against your upper lip.

The second one is an "older" model civil type probably from the 1960's. It has the little ridge for the upper lip and I can remember using one like this.

We old guys have to stick together. These "kids" don't always know what we are talking about.
