I’m spoiled. The place where I live is quiet. Sitting in my back yard, I hear mostly birds and the wind. Occasionally a plane or helicopter flies over from the small airport a half mile south, and sometimes I hear a truck gearing up on Highway 101. Sometimes the ocean whispers and sometimes it roars, but overall it feels quiet. Or maybe it’s just that I don’t hear as well as I used to. As noted in earlier posts, I have a measurable hearing loss typical of people my age. But in my yard, I can almost hear the quiet.
Gordon Hempton, author of a wonderful book called One Square Inch of Silence, would disagree. He would say it’s pretty good, but it’s not truly quiet here in South Beach. If he measured the sound levels here, he’d probably come up with about 35 decibels coming from cars, waves, and miscellaneous mechanical sounds that I don’t notice. When a helicopter passes over, it would go up to about 90. Wherever we live, we become accustomed to a certain level of noise: cars, lawnmowers, TVs, appliances, dogs barking, people talking, and so much more. Some of us even become uncomfortable if it’s too quiet. We reach for our iPods or turn on the TV. I confess that sometimes I sleep with the radio on.
Gordon Hempton specializes in sounds. He makes his living mostly from making and selling recordings of birds, beaches, and train whistles. But his favorite sound is no sound at all. He prefers quiet, quiet enough to hear your own footsteps or the chorus of birds that greets the new day. But quiet is hard to find. Even places billed as quiet are filled with the noise of cars, planes, trains, and people. He’s on a mission to set aside one square inch of silence in Washington’s Olympic National Park, making it a place where people don’t speak and planes don’t fly over. As part of that mission, he drove across the country to Washington, D.C. in a VW bus, measuring sounds in cities, parks and wilderness areas. His book is the story of that journey. I found the book fascinating and enjoyed the way the science is folded into an engaging story. I also learned a great deal about sound.
Did you ever think about the fact that our hearing is designed to keep us safe, that most animals depend on their ability to hear predators coming so they can react to protect themselves. Animals won’t nest where it’s too noisy because they can’t hear, Hempton says. For us people, that might mean hearing a car coming so we don’t get run over, hearing a rattlesnake before we step on it, or hearing someone knocking on the door. We need to be able to hear a baby cry or a loved one shout for help. We need to hear each other in order to communicate. Hempton says we don’t have “ear lids” because we need to be able to hear all the time.
But it’s getting to be so noisy we can’t be sure we’ll hear anything. On his travels, Hempton visited a symphony hall, the Indianapolis speedway, and a basketball game. All were so loud it was nearly impossible to converse and the sound levels were high enough to cause damage to people’s hearing. Even in many of the restaurants he visited, it was too loud to talk. The roar of conversation, kitchen noises and Muzak added up to an audio attack. Even in places where people assured him it would be quiet, places like national parks and areas deep in the wilderness, Hempton found planes flying overhead every few minutes and power plants roaring 24/7.
All of this makes me glad to live where it is relatively quiet. Of course, there’s a price to pay. Mid-morning on my street, I’m the only human around. It gets lonely. At my desk, I hear a hum from the refrigerator, I hear my computer keys clacking, I just heard a fly bounce off the window. If I pay attention, I can hear myself breathing. But as soon as I get in my car, I turn on the radio as I ease into a world of noise, a world where quiet is becoming harder every day to find.

I found a free app for my phone that measures sound. It rates the sound here in my office right now as a whisper. Is it quiet where you are? What kind of noises surround you? Do you notice them most of the time? Let’s talk about it in the comments. Quietly.
One thought on “Can you find one square inch of quiet?”
I live in the suburbs of a large city. I think where I live is reasonably quiet most of the time, by urban standards. There’s the occasional passing traffic from the next street behind, and the weekend always bring the mowers, whipper snippers and leaf blowers out.
If the wind blows the wrong way (not too often) we hear the noise from the motorway a km or so away. Windy days always bring the sound of the wind in the gum trees. On Fridays when they change the flight paths we hear the passing planes flying high overhead. If I’m outside I always look up and wonder where they are flying to.
My aunt visited from the country for a few days and commented about how quiet our location is. Most mornings I hear the warbling of the magpies while having breakfast, then during the day the parrots and other birds fly through at their usual times; There is always cicadas in the summer, often too loud I think, and crickets at night. An urban jungle of sorts.
