Methods for reporting perceived sound source directions were compared. To estimate the localization bias introduced by the reporting method from the location percept to the judgment given by the subject, a simple non-audio based approach was proposed. Training strategies were used to simplify the reporting task. The first evaluated method was a graphical interface showing three schematic 2D views of a spherical head on which the subject reported his localization judgment with the mouse. An enhanced version of this 2D interface was designed, with feedback on the reported direction, using an individual 3D visualization of the subject and indicated direction. Sound localization tests with this interface are compared to tests using the 'finger pointing' method.
