Abstract
After measuring the acoustics power of different types of machines, some problems have arisen due to the measurement methods used (ISO 3744 and ISO 9641-2). Background noise in the key factor, that makes, in some cases, the measurement not possible, either by lack of difference with the level of the signal to be measured, or by the increase of the interferent intensity in the room. According to this, another way to measured is thought, in which the background does not interfere. To achieve this aim, lind source separation (BSS) techniques haven benn tested, evaluating different algorithms and selecting those thay give the highest reliability to create the method of measurement that must be applied in those problematic cases.
