I wonder if wearing a reflective face shield would be a more effective deterrent to interruptions. If people can't see your face then they would probably be much less likely to engage in conversation. You could just take a normal face shield and put reflective sunscreen window film on the inside.

I think this would work the opposite way because people would think it's a great conversation starter.

You make a good point. Maybe it would need to also be worn with hearing protection until the novelty wears off. And adding a chin strap would prevent other people from removing it.
