The larger lecture halls in which I've lectured all have microphones, decent amplification and decent JBL speakers. They'll need to add equalizers to boost the mid-range frequencies that are muffled by a mask yet are critical for understanding speech. The bigger question, I think, is how many faculty will be willing to offer in-person instruction in a no-vaccine setting, regardless of the mandatory safeguards?
