METHOD FOR MONITORING A LIVESTOCK FACILITY AND/OR LIVESTOCK ANIMALS IN A LIVESTOCK FACILITY USING IMPROVED SOUND PROCESSING TECHNIQUES

摘要

The invention concerns a method for monitoring a livestock facility and/or livestock animals in a livestock facility. It includes receiving audio signals comprising sounds generated in a livestock facility from two or more microphones. Sounds of interest in the audio signals are localized, the sounds of interest being both sounds generated by livestock animals and sounds generated by noise sources. The localization further comprises the steps of utilizing models of noise sources in an airspace based on localization in noise reduction algorithms to filter off noise sources from the audio signal, resulting in a filtered audio signal, and the step of analysing the filtered audio signal.
