Krause calls the sounds made by living things biophony and those made by nonliving parts of nature (such as wind, water, or thunder) geophony. Then there’s anthrophony: the sounds humans make. If our roads, airplanes, or jackhammers drown out the natural soundscape of an ecosystem, how are other living things affected? That’s one of the questions Krause hopes his recordings will help answer. Some of the soundscapes he’s captured have already shown the effects humans can have on the environment. In a meadow in the Sierra Nevada mountains, Krause made recordings both before and after a 1988 logging operation. The lumber company promised that by only cutting down a few trees here and there, it would preserve the environment. But the microphone told a different story: when the logging was over, the richness and diversity of the soundscape was gone. With much of their habitat taken away, many birds (and their voices) had left the meadow.
