Conclusions
•The
use of Eigenmike coupled with virtual microphones methodology allowed to inspect the sound field inside a
car’s cabin
with higher spatial resolution compared with low-order microphone arrays.
•The
false-color maps obtained during noise measurements provided consistent results with these hypotheses:
–low
frequencies components of noise are mainly due to chassis vibrations;
–at high frequencies the
doors/windows leakage become noticeable
