Thank you for that question.
I can tell you that the platform is the problem. Of course, wearing headsets and having an Internet cable connection should be mandatory because we obviously can't interpret your remarks correctly if we can't hear what you say.
However, it's not just the volume issue. All too often, when we tell people we can't hear them, they turn up the volume. However, what we need is to hear your remarks clearly. You have to understand that we're listening to what you say, processing that information and speaking over your voice. Suddenly, the volume goes up. That's where we risk getting injured because sometimes the volume's too high.
So what you can do as members is reconsider the set-up. I don't really know whether it's possible to consider another platform than Zoom at this point. However, interpretation platforms do exist. You could definitely—and I urge you, implore you and beg you to do it—make it a mandatory rule to wear a headset with an integrated microphone and to get an Internet cable connection.
