I went to campus yesterday to finalize the preparations for my first day of in-person teaching since March 2020. Among other things, this involved testing out the gear I’ll be wearing in the classroom, facing a total of about 90 mostly vaccinated students.

Pictured or implied:
- A deceptively calm instructor in a self-administered haircut
- A KN95 respirator on the FDA’s (now-defunct) emergency use authorization list
- An “ear saver” that maintains a tight seal around the KN95 while relieving strain on the ears during extended use
- A $30 rechargeable personal PA system worn on a strap, with a wired headset, to allow me to project my voice effectively through the mask (over the whir of the classroom’s air filtration unit) without shouting
I think it should work. It’s going to be weird as heck, but it should work.
