3D sound reproduction through stereo inner-phones
MetadataShow full item record
A 3-D sound reproduction method through stereo inner-phones is proposed. This method uses HRTFs and a correction filter, Hc, which compensates the changes of the transfer functions of the ear canals caused by insertion of the stereo inside-phones. The results of the localization tests in the horizontal and the median plane indicated that the perceived direction agrees with the simulated one. Furthermore, non-individual HRTFs among subjects are selected by localization tests. The detailed observation of the selected non-individual HRTFs shows that they have emphasized characteristics in directional dependence.
