Week 4 Quiz

Checking whether this week's noise-propagation reading landed.

Week 4

Three questions on how sound and enforcement actually work in a library.

1. Why does the lecture call a library's noise floor "a design goal, not an accident"?
2. What does the lecture say makes the shush unusual as a countermeasure?
3. What actually enforces "the library is quiet" as a norm, according to the lecture?
4. A five-minute phone call goes unchallenged; a ten-second shush in response draws visible reactions across the whole floor. What does this asymmetry tell you about how the room enforces its own norms?
