Conclusions
nThe sound quality evaluation is heavily
affected by the presence
of car’s background noise;
nThe questionnaires employed for evaluation in
absence of background
noise revealed to be partially unsatisfactory for assessing sound systems in presence of
background noise;
nTechnicians used to evaluate sound systems by
listening to music
reproduction inside a silent environment need some further training for becoming used to
listening with background
noise;
nThe hybrid reproduction systems revealed to
be satisfactory for
the reproduction of the sound recorded inside a car compartment, and can be further improved by
means of a portable
multichannel soundboard;
