Hah, I did consider sticking a microphone on these and making them steadily tick down as people talk to you but I decided that might come across as being a bit passive aggressive... (although I have been told that pressing the button to reduce the level mid-conversation is a very effective way of getting people to leave you alone!)

I agree. If I had this hypothetical device I’d want it to be hidden. This could probably be a smartwatch app. But making a custom device is more fun!
