Abstract
The purpose of this paper is to show the capabilities of MicrodB's acoustic imagery algorithm to characterize rotating sources. First part will explain the main specificity of the treatment. In the second part, possibilities of analysis and validations on simple tests will be demonstrated. In the last part, an industrial application will be studied : a Technofan extract fan with a 10000 RPM rotational speed will be analysed. Both fixed and rotating sources will be separated, allowing the localization of rotating sources on the blades.
