For a Study Abroad program in May 2016, Dr. Scott Hawley, physics, wrote “Polar Pattern Plotter,” an iOS app used for measuring sound directivity of loudspeakers and microphones. The app was released on the App Store last year. He also wrote a journal paper on the app, “Visualizing Sound Directivity via Smartphone Sensors,” (written in collaboration with Nashville sound engineer Robert McClain, Jr.) that has just been accepted for publication by the The Physics Teacher. A pre-print of the paper is available here.
Hawley has made the app Open-Source in order to foster its development as a community tool. The code is available here.
