Stop, Hey, What’s that Sound?

Think of any type of habitat and you’ll probably first imagine what it looks like—the terrain, what kinds of plants grow in it, and which animals make it their home. But sometimes it’s the less tangible characteristics of a place that can speak volumes about its ecological health: sounds. No one understands that better than ecologist Bernie Krause, who has spent the last 45-odd years recording the soundscapes of more than 2,000 habitat types, both marine and terrestrial. Biophony unaltered by human activity, whether it's traffic, construction, or logging, is increasingly hard to come by. In his new book, Voices of the Wild: Animal Songs, Human Din, and the Call to Save Nature, which hit shelves yesterday, Krause explains the ecological and cultural importance of lending an ear to the wild.

The recordings below, a small sampling from Krause’s library, are examples of how humans bring the noise, and, all too often, the sound of silence.
