Hearing, in short, is easy. You and every other vertebrate that hasn’t suffered some genetic, developmental or environmental accident have been doing it for hundreds of millions of years. It’s your life line, your alarm system, your way to escape danger and pass on your genes. But listening, really listening, is hard when potential distractions are leaping into your ears every fifty-thousandth of a second — and pathways in your brain are just waiting to interrupt your focus to warn you of any potential dangers.

Listening is a skill that we’re in danger of losing in a world of digital distraction and information overload.

And yet we dare not lose it. Because listening tunes our brain to the patterns of our environment faster than any other sense, and paying attention to the nonvisual parts of our world feeds into everything from our intellectual sharpness to our dance skills.

Luckily, we can train our listening just as with any other skill. Listen to new music when jogging rather than familiar tunes. Listen to your dog’s whines and barks: he is trying to tell you something isn’t right. Listen to your significant other’s voice — not only to the words, which after a few years may repeat, but to the sounds under them, the emotions carried in the harmonics. You may save yourself a couple of fights.
