Abstract

|
| Passive acoustic localization is a non-intrusive method that can be used for animal localization on species that emit vocalizations. Low-cost microphone arrays are an excellent tool in these experiments due to their ability to spatially localize the vocalizations. Accurate spatial calibration of the microphone positions remains an expensive or labor intensive step. Especially given the fact that bio-acoustic experiments can be performed in a wide range of environments such as indoor flight cages with easy accessible walls and a ceiling, as well as outdoor environments, where walls and ceilings are hard to come by. In this document, we present a low-cost tool that can be used to create an acoustic calibration signal. This tool allows for a faster and more robust calibration of the microphone positions while reducing the computational complexity of the calibration phase. This tool enables any researcher to calibrate the sensor array without knowledge of the sensing system. |
