Abstract

In this paper an analysis of moving sound source localization via headphones is presented. Also the influence of the inter-click interval on this localization is studied. The experimental sound is a short delta sound of 5 ms, generated for the horizontal frontal plane, for distances from 0.5 m to 5 m and azimuth of 32° to both left and right sides with respect of the middle line of the listener head convolutioned with individual HRTFs. The results indicate that the best accurate localization was achieved for the ICI of 150 ms. Comparing the localization accuracy in distance and azimuth is deduced that the best results have been achieved for azimuth. The results show that the listeners are able to extract accurately the distance and direction of the moving sound for larger inter-click intervals.
