I am a 58 years old engineer and my interest goes mainly to ESP32 IoT applications which I program with Arduino IDE and microPython. I use simple Flask and node-red servers in the cloud.
The I2S YouTube intro from BILL brought me to this group and I hope to share some ideas and code about I2S.
Currently I got stuck in a project and I hope to find some help here.
I want to use a flat I2S MIC, put it in an FFP2 mask and forward the sound to an I2S DAC and try to minimize the feedback/oscillation with some digital filters or delays from the library. Maybe an extra LED to indicate who is speaking would be nice.
I believe teachers, students, doctors and nurses will be more happy to use FFP2 masks the next 10 waves if they can be understood better 🙂
Have a nice weekend!

I am not convince there are folks here to help you, it sounds like you are the expert
I am probably wrong, but are you talking about face masks? The reason people don't understand is nothing to do with sound being blocked (it isn't) by the mask, it's because we are all unconscious lip readers to one degree or another and when we can't see the lips we have less input. I am a hearing aid wearer for the last 15 years due to normal age degradation so I have been made very aware of how we all process speech.
Welcome to the forum, but as I said, you sound like more of a resource than a consumer of same.

Sure you can learn to be a programmer, it will take the same amount of time for me to learn to be a Doctor.

Yes I mean closed face masks FFP2. I agree seeing/reading the lips is important too.
But you have to speak much louder in a classroom to be understood with a mask and without an amplifier.
I used one like below in my classes but it is to big and expensive for students, general purpose/mass product.
