Nah, more like a classroom or an auditorium, where you just don't expect to see everybody's faces, but they can still raise their hand and speak.

When I speak in a classroom or auditorium, I always expect to see people's faces.

Truly?

Imagine you're in an audience. Somebody two rows behind you raises their hands and asks a question. Do you leap to your feet so you can turn around and stare at their face?

Most people certainly don't. Ditto if the person is otherwise hard to see. They just listen and it's fine.
