Interesting microphone application - "Acoustic telescope"

Discussion created by JeradL on May 21, 2013

I came across this DesignNews Gadget Freak article last week. This shows a design using an ADMP504 low-noise microphone paired with a reflector to create an acoustic telescope to pick up sounds within a narrow angle. The circuit in this design is based off of some of the recommendations in app note AN-1165. This looks like a fun project and it sounds like he's happy with the results he's hearing!
