The beamforming technique makes it possible to obtain an acoustic map in real time which is superimposed on the photographic image of the investigated source; this makes the acoustic characteristic of the latter visible, generating an image which, in terms of frequency, allows the origin and the sound pressure level to be outlined.
Thanks to a powerful array of microphones, the change in acoustic pressure detected by the sensors is converted into a set of pixels returned to the video.
The result is a series of high-definition images or videos capable of pinpointing with precision, both in frequency and in level, the points where the acoustic emission is most problematic.
Thanks to this innovative system, it is possible to optimize the design of machines, equipment and components but also to remedy, during construction, problems relating to noise emissions.
The acoustic source localization system using the intensimetric method allows you to create high-definition acoustic maps or movies with a high visual impact that are easy to interpret.
Spacing, array size, and number of mics determine the dynamic range and resolution of the instrument. With 120 microphones (matrix below) it is possible to carry out investigations starting from 40 Hz.
The applications with the instrumentation used for these investigations are manifold. You can investigate the criticalities in the structures by seeing where there are acoustic bridges; it is possible to identify where impulsive noises produced, for example, by machinery, even of large dimensions, come from. With ultrasound cameras, gas and liquid leaks are identified. In all those cases where the sound level meter cannot give us the solution.
Ideal for all acoustic testing and diagnostic services where it is important to identify the source of disturbance, ECO Next performs diagnostic activities with the use of high definition image acoustic video cameras.
