Sentence examples for microphone array imperfections from inspiring English sources
Figure 8 Effect of microphone array imperfections on beampatterns.
Figure 9 Effect of microphone array imperfections on steering vector.
Effect of microphone array imperfections on steering vector.
Moreover, the overall system robustness against microphone array imperfections and noise presence has been experimentally evaluated.
The robustness of the overall algorithmic framework has been experimentally analyzed with respect to the microphone array imperfections and noise presence, in different configuration case studies.
As final test, the effect of noise presence on echo cancelation performance has been evaluated, without taking the aforementioned microphone array imperfections into account.
Effect of microphone-array imperfections on beampatterns.
Instead, Figure 9B,C report the error surfaces for the cardioid and hypercardioid case studies: the microphone array position imperfections have a reduced impact with respect to the omnidirectional case, but now the orientation perturbations influence the BF characteristics.
Fixed broadband BFs employing small microphone arrays are typically sensitive to array imperfections.
Figure 9A shows the error behavior in the presence of omnidirectional microphones: it is evident that the BF is only sensitive to the position and not to imperfections of the microphone array orientation.
Moving from the same experimental scenario considered in simulations in Section 3.2a, the ERLE curves have been here calculated under different operating conditions, corresponding to different array imperfections for different microphone polar patterns.
