If you’re a librarian who thinks everyone can hear you so you don’t need the mic, you’re wrong and when you feel embarrassed that people yell at you, that’s what you get for not caring about other people I’m sorry. 🤷🏻‍♀️  

It’s 2025. How do you not know people having hearing issues or that people behind you won’t hear as well as people in front of you.

@platypus Not just hearing impairment! There is a much more subtle #accessibility issue the mic eliminates.

In a room of any size, even if the speaker's voice is "audible" (to non-impaired hearers), sound dynamics change dramatically as the speaker moves around, or even faces different directions.

This effect introduces a significant source of cognitive load.

Your job as an educator is ruthlessly to minimize cognitive load. Use a mic.

I mean, unless Ruth is there? Then do it ruthfully

@jameshowell @platypus JFC the number of time's I've had to practically *beg* speakers to "please use the mic, it's a very large room". You'd think I was commenting on their **** size or something....

@48kRAM @platypus After twenty long years and more in academia, I have learned never, but never, to underestimate the pettiness and delusion of my colleagues' self image

which internally is this

@jameshowell @48kRAM @platypus Brings to mind that old joke about why academic department politics are so vicious...

Because there's so little at stake.

@randyridenour @48kRAM @platypus My joke is that we all think everybody is hypnotized by our presence and that thousands can hear our stirring words on a battlefield
