DIY Sound Localization Sensor with Arduino
We have covered loads of motion detection projects, but what about sound? A sound localization sensor helps you to identify the location or origin of a detected sound and find out its direction and distance. Our ears do it for us, but building an artificial signal processor takes some work. The military has expensive equipment for this, but if you’d like to do it yourself at a low cost, this is for you.
The DIY sound localization sensor uses an operational amplifier circuit alongside an Arduino and servo. The circuit amplifies the signal from three microphones, compares their amplitudes, and determines the origin location of the sounds. Project files are available so that you can start building a localization sensor of your own.
