A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

This is a science community. We use the Dawkins definition of meme.
Is it possible to record those higher frequencies and then turn them down so I can hear how noisy it is for my dog at home?
Probably. If astronomers can convert the radio noise stars make into audible sound - and they can - then I don't see why we couldn't pitch adjust background noise to human-audible levels.
I'm not 100% on the pitching down bit, but key would be to get a mic that has those frequencies in its range.
You also need to have a sampling rate that's equal to 2x the highest frequency you want to capture.
