Funny story, in my biol class the ac is too cold…so the prof brought in 4 electric space heaters to warm up the room. Cant hear him over the sound of the A/C and heaters fighting.
Set up a wireless microphone by him at the front of the room. Hook the receiver up to headphones with active noise cancellation — those do a really good job of filtering out fan noise.

I’ve always felt that humanity can overcome, or at least mitigate, any hurdles opposing it via use of money and technology.
