The classification of sheep and goat feeding phases from acoustic signals of jaw sounds

摘要

This paper describes and documents investigatory work for the detection and measurement of sheep rumination and mastication time periods from jaw sounds transmitted through the skull. The rumination and mastication time periods were determined by a neural network classifier using a combination of time and frequency domain features extracted from successive 10 second acoustic signal lengths. It is shown that spectral features contain most of the information required for good classification.
