The Saltiphone is a sensor for measuring wind erosion. Wind erosion can degrade a soil's fertility as soil particles are blown away, conversely in coastal areas wind erosion can strengthen sand dunes and stimulate vegetation growth.
Particles hitting the microphone produce high frequency noise, which can be distinguished from other noises caused by wind and rain. Frequencies of about 8 KHz are amplified and used to determine saltation.
