Abstract

We use four sound sources to dynamically calculate a sensor’s location in three dimensions. Each sound source emits beeps at its own predefined frequency. The beeps are repeated at regular intervals. The computer uses Fourier transforms to recognize the signals and determine their arrival times. Using the computed delay of the signal arrival times, we compute the distance to each of the sound sources. We then use these distances to determine the sensor’s position in three dimensional space.
