Ask HN: Where is that noise coming from?
As a fun experiment, say you’re in a (mostly) silent house and there is a faint, irregularly timed noise that sounds pretty similar each time.
At your disposal you have yourself, your cat, another person, and two modern smartphones. You’ve tried wandering around, and you just can’t figure it out off the top of your head.
What technical/non-technical method would you use to locate the source of the sound?

- fargle 4y agoput the two smartphones in the freezer. put the other person and the cat in the rear bedroom and lock the door. cotton balls. if you don't have them, you can cut up your socks. you put them in your ears. if the sound keeps on, then the source of the sounds is just that you're crazy and delusional. if not, it's just the furnace it doesn't matter which, because the other human will have called emergency services and you'll be going to a nice place
- ggm 4y agoInstall a recording app on the phones, put one in a soundproofed location and turn both on and do a differential between what they record. Once you are satisfied on playback there is a signal, start doing triangulation.
