Hello!
I'm working on a noise reduction project for aviation headset (ANR).
What kind of electret microphone should I use, I tested several and high frequency feedback occurs, the last I tested was this:

The original microphone works fine in my circuit, but it is not possible to know the manufacturer and specifications.
Any help will be welcome.

Best regards

ACPC

Noise cancelling microphones are of different construction than regular microphones and basic electret capsules are not suitable for this purpose. You could use two electret capsules back-to-back and electronically manipulate noise reduction. E
