Sound source localization errors occur. The second experiment aims at assessing the effect of localization errors on sound quality judgments of heavy-duty diesel engine noise. The results show that localization errors can influence localization judgments. The following step is to try to eliminate localization errors in binaural recordings. Therefore the third experiment assesses the influence of the short training session, priori to listening to binaurally recorded sounds, on localization performance.
Results show that training can help to avoid localization errors for certain acoustical conditions.
