Thinking of putting a wind turbine in your backyard? Mariah Power is introducing a program that will let you measure the wind speed around your house by pointing your iPhone toward the sky.

The application uses the phone’s microphone to capture wind noise. It filters out ambient sound and an algorithm converts the result into a decibel rating that corresponds to wind speed, according to Bill Westerman, a principal at Create with Context, a Silicon Valley digital design company that developed the app for Mariah.

“If you go out in your backyard and do a few measurements it gives you a pretty good idea of the wind speed and tells you what kinds of things you could power with a wind turbine,” said Mr. Westerman.

Mariah, based in Reno, Nev., makes the Windspire, 1.2-kilowatt residential turbine with horizontal blades that looks more like a piece of modern art than a conventional windmill.
