My ears started to take some damage and had to turn the video lower in volume. It is indeed distracting, but remember that people are in academics not because of their performance skills, but because of their research skills and interests. Of course, any academic should learn speech and performance at least a little because those things hold pedagogical value. Also microphone is obviously bad, which is unfortunately common in content like this. It's hard to understand why academic content creators aren't aware of how important good audio is for viewer engagement.
