There are 31,557,600 seconds in a year. And every year, 55 * 10^9 animals are killed (in the U.S.). That means at a frequency of 1.743kHz, life is extinguished, day and night. Just image a single wince of pain coming from getting punched unconscious. And then in the semi-hazy state, throat is slit as life grinds to halt, skin is removed. But it doesn't happen just once... it happens so often that if there was a single faint tick of clock each time, it would blur together into a high-pitched whine in the center of the most sensitive portion of hearing (between 1kHz and 4 kHz). 24 hours per day, every day of the year!
