Barn owls' hearing inspires new electronic devices for wayfinding

Originally published at:


We have an owl living on the property in Joshua Tree, he eats a lot of rodents / ground squirrels. He’s ok in my book.


Any cell phone has more than enough horsepower to do this without special circuits. Seems like something for people who like listening to phonographs through vacuum tubes.

A few years ago I saw a article about nano directional microphones and how a array of those in the future could be used to create a sound “camera”.

I’m still waiting, this could be really useful in troubleshooting that annoying noise my refrigerator makes.
