Since I'm an industrial engineer, not an interpreter, I've had a fair amount of training in the field as well.
Yes, we're considering a number of technical measures. You mentioned the earpiece, for example. There are ways to ensure that it mutes as soon as the user removes it. As for sound, we can reduce Larsen effects by digitizing the sound and thus limit the risk. I'm thinking of the people who are attending today's meeting via Zoom. The danger occurs when you're in a somewhat more analog acoustic environment. So that's another factor that we're looking into.
At concerts, for example, you see singers wearing earpieces that are pushed inside the ear. That limits Larsen effects and vastly improves the situation.
In our case here, we want many people to use earpieces. We could consider having you use earpiece models that belong to you. We're working with our colleagues on that. We don't do audiovisual work; we supply people, the living beings who are the interpreters and who enter the room. However, we're working with people to come up with the technological tools that could completely eliminate Larsen effects. They're out there and we're looking into this because we obviously want to reduce the number of interruptions for you.
