Here is something from ifixit.com that supports most likely no damage will result from accidentally putting the sim ejector into the microphone hole

Furthermore, the channel that carries sound from the hole on the phone’s frame into the microphone module on the board is often L-shaped, so even if you stick an eject tool into the mic hole, it won’t even get close to the microphone electronics anyway.

Here is another one

“The answer is No. Pretty much every phone is built the same way. Microphone hole fits the ejector tool purely by coincidence. But the white impermeable layer (on microphone hardware) is to the side of the shaft and not directly in the end. No matter how deep you go, the tool won’t puncture any of the water resistance or poke the microphone hardware,” he said.
