Description
Summary:In this document are presented how, by the use of the Microflown Technologies’s P-U probe, is obtained the localization of a sound source. This source localization is tackled by two techniques: by the recognition of the acoustic intensity vector and using the beamforming technique. Also, this document presents the methods to carry out the measurements, the restrictions of the source characteristics, the limitations of both techniques and the actual used procedures. The localization is plied to two different sound sources, an electroacoustic source radiating a controlled signal and a non-electric-acoustic source (a blender motor). For both sources it is wanted to obtain its localization in two different places: A closed space, with low levels of background noise and controlled absorption, and an open space. From the results it’s made comparison between the found localization for different frequencies, between the evaluated sources and between the chosen places.
