Headphones work best for people who need or want to hear one sound story and no other; who don’t want to have to choose which sounds to listen to and which to ignore; and who don’t want their sounds overheard. Under these circumstances, headphones are extremely useful — and necessary for sound professionals, like intelligence and radio workers — but it’s a strange fact of our times that this rarefied experience of sound has become so common and widespread. In the name of living a sensory life, it’s worth letting sounds exist in their audio habitat more often, even if that means contending with interruptions and background sound.Make it a New Year’s resolution, then, to use headphones less. Allow kids and spouses periodically to play music, audiobooks, videos, movie, television and radio audibly. Listen to what they’re listening to, and make them listen to your stuff. Escapism is great, and submission and denial, too, have their places. But sound thrives amid other sounds. And protecting our kids’ hearing is not just as important as protecting their brains; it is protecting their brains.
