For a long time I thought the problem was all in my head. When I was growing up, I knew that a certain kind of noise was one I needed to avoid. Food blenders in the kitchen, hair dryers in the bathroom, a vacuum cleaner whooshing around—all produced an intense whining sound that, given the specific wiring connections between my ears and my brain, kept me from thinking about anything but the sound itself while it was going on. Over the years I lived by this code: I used high-performance earplugs if I needed to write or otherwise concentrate while sitting in some place that was unusually loud. I added noise-canceling headphones on top of the earplugs in really tough cases.
As time went on, the earplugs-plus-headphones protection rig became standard writing gear. That was because the use of gas-powered leaf blowers in my Washington, D.C., neighborhood evolved from a few hours a week during the leafiest stretch of autumn to most days of the week, most weeks of the year, thanks to the advent of the “groomed” look that modern lawn crews are expected to achieve. One of my longest-running themes as a journalist has been how changes in technology force people to adapt their habits and livelihoods. I thought I was doing my part, with gear that let me attend to my work while others attended to theirs. There even turned out to be a bonus: As other parts of my body went into a predictable age-related descent, my hearing remained sharp.
