To celebrate National Protect Your Hearing Month, Bar1 sent out this promo in the form of a simple hearing test. If you can hear the 3 frequencies, congratulations! You can still hear! (Apparently my cat can hear them too, judging by how quickly she dashed out of the room.)
I love creepy Norman Rockwell-esque image as well as the real point at the bottom of the ad: the fact that Bar1 protects our hearing and saves "the world from crappy audio since 2006."
