A clear explanation from the basics of sound and vibration to the analysis technology of abnormal noise inspection devices!
At Daioh Electric Co., Ltd., we are offering a technical document titled "Fundamentals of Abnormal Noise Inspection," which summarizes the sound and vibration analysis technology and inspection algorithms used in our abnormal noise inspection devices. This document covers basic topics such as what vibration and sound are, the concept of accelerometers used in vibration inspection, and progressively explains representative methods for detecting abnormal noise, including FFT (Fast Fourier Transform) and the Mahalanobis-Taguchi method. This content is useful not only for those who want to understand the mechanism of abnormal noise inspection devices but also for those considering the automation of auditory and vibration inspections in the future.
