Won't this just make the students talk even louder?

Here's a humdinger of an article from across the Pond. I guess out-of-control students are not just an American phenomenon. The chatter in classrooms across Europe is apparently so bad, teachers are being urged to use microphones in the classroom in order to be heard above the din:

Teachers are being advised to use microphones, loudspeakers and other techniques to save their vocal cords.

Give the teacher a microphone. Would it be too much to expect the students to stop talking over the teacher? In our current culture - both here and in many parts of Europe - I guess it is. This is what happens when the sense of entitlement in prosperous countries begins to take over.

Good Day to You, Sir
