The engineers have given us a very clear answer. They measured a completely wired set-up, and even Zoom “advanced”, which is specified to reach 15 kilohertz, which is the absolute minimum we need, did not meet that threshold.
I'm afraid, then, the answer is no. It will help, of course; everything we do will help. The interpreters will just have to suffer through it, I'm afraid, and live with the hearing damage that is inflicted during COVID on this generation of interpreters, to some extent.
The less loud we have to turn the original, the more it helps us, of course. We have to find a way of dealing with this as best we can.
