The need to detect faults in industrial machines has been growing significantly due to the increasing complexity of production processes and the greater demand for reliability and availability of these systems. This has led to advancements in research based on machine learning and deep learning, accompanied by the development of new signal processing techniques. However, one of the main challenges in this area remains the treatment of signals, especially acoustic signals, which are highly noisy – a common situation in industrial environments due to the simultaneous presence of various equipment and noise sources. In this context, this work proposes an approach that integrates Empirical Mode Decomposition (EMD) and cyclostationary feature extraction as preprocessing steps, combined with automatic detection using One-Dimensional Convolutional Neural Networks (1D-CNN). This integration aims to improve fault detection performance, offering greater sensitivity to characteristic fault modulations and increasing robustness under conditions of intense noise.
