Direction and Ranging of an Incoming Sound from an Arduino Sound Sensor System Mantle, Luke; Soroco, Mauricio
Abstract
Sound detection and ranging has many applications related to echolocation, navigation, and geolocation. All rely on accurately pinpointing the location of the source with the use of sound delays. For this study, we assembled a device that could pinpoint the location of a sound source with the use of differences in times of arrival of its sound. It consisted of three sound sensors connected to an Arduino circuit board, which sent data to be processed in Python. The device was found to function correctly to some accuracy. We found that the magnitude of its error varied with the relative location of the sound source and sensors. This led to the production of a model for the error that lets the machine generate a two-dimensional probability distribution as a heat map for the location of the sound source by combining any single measurement with the experimentally determined uncertainty in the equipment. The probability distribution generally matched the machine’s actual distribution of outputs.

Sound detection and ranging has many applications related to echolocation, navigation,

delays. For this study, we assembled a device that could pinpoint the location of a sound source
with the use of differences in times of arrival of its sound. It consisted of three sound sensors
connected to an Arduino circuit board, which sent data to be processed in Python. The device was
found to function correctly to some accuracy. We found that the magnitude of its error varied with
the relative location of the sound source and sensors. This led to the production of a model for the
error that lets the machine generate a two-dimensional probability distribution as a heat map for
the location of the sound source by combining any single measurement with the experimentally
determined uncertainty in the equipment. The probability distribution generally matched the
machine’s actual distribution of outputs.
