Is it posssibel to determine sound ranging with arduino ?

i just read artikel from http://www.tgdaily.com/hardware-features/54743-portable-bullet-detectors-issued-to-us-troops and Artillery sound ranging - Wikipedia. Is it possible make prototype using arduino ?

Thanks.

There are many different sonic distace sensors, some super cheap ones for $2 like the HC-SR04(still great) and some big bad ones like this Ultrasonic Range Finder - XL-MaxSonar-WR1 - SEN-09496 - SparkFun Electronics.

Using an array of sonic sensors, pointing in all directions, it could possible to identify the direction of a noise, especially one as loud as a gun.

Pretty weak on the details but yes, an Arduino is plenty fast for it.
