Abstract

OLIVEIRA, Aline Cabral de et al. Head related transfer function relevance to sound source localization. Rev. CEFAC [online]. 2008, vol.10, n.3, pp.385-391. ISSN 1982-0216.  http://dx.doi.org/10.1590/S1516-18462008000300014.

PURPOSE: to investigate the relevance of the head transfer function related to the sound localization by human normal hearing, in reverberant environment; to correlate the percentage of success in sound localization and the length and the width of the head and the shoulders, observing the difference among frequencies and the spatial planes. METHODS: the sample was made up by 52 individuals, 20 men and 2 women, which had been submitted to otoscopy, tonal audiometry and OAE. The measures related to length and width of the head and shoulders had been carried out too. Later, the individuals had been submitted to sound localization test, in the horizontal and vertical planes, and with the frequencies of 0.5, 2 and 4 kHz. Results: significant correlation was obtained (p<0.05) just between the width of the shoulders and the success in the horizontal plane, using 2 and 4 kHz. CONCLUSION: The percentage of success in the sound localization increases with the increase in the length of the shoulders using 2 and 4 kHz, in the horizontal plane.
