I’m trying to cram in some last-minute neurobiology studying right now, and this sickeningly annoying noise that sounds like a British air raid siren is at it again for the umpteenth time this week. Anybody know what the hell it is? The thing blares for about a minute any time. I’ve narrowed down the possibilities at this point to me going insane (though my roommates hear it as well, which might mean collective insanity) or Northwestern testing a violent assailant alert system. Really can’t think of anything else. Next time that noise comes up again, I’m recording a sample of it.
