| Descripción: | The harmonic structure of sonar echoes was analyzed using aural cues for differentiating between two classes of signals. The return echoes of many types of solar systems from targets of interest are indistinguishable from non targets. The subjects were individually tested and on each trial a sound was dichoticly presented over the subject's headphones. The mean of the subjects median ratings of perceived timber for each sound in each block was calculated for both subject groups. |
