> Do you remember when you were debilitated by a strange noise? You'd find a few percent of adults who can hear above the 17khz range who are plagued by buildings with bird deterrant signals. And professionals that can hear poorly made transformers used in fluorescent lights and major electronics. Anecdotally, my worst cases were the home Depot bird deterrer in a garden center, that every 5 seconds I would wince and lose my balance and much peripheral perception. And in an accelerator cohort of 40 20-40 year olds, 2 of us had to hunt down the tv with a loud transformer in the open office room while being thought insane by the rest of our cohort.
