Music sound restoration and the effect of presentation conditions

When a music sound in a melody was deleted and replaced by a noise, a missing sound can be restored perceptually. This illusory phenomenon in audition, named music sound restoration, can be proved indirectly by inaccurate judgment of temporal position of the inserted noise. In the present study, music sound restoration was investigated in terms of the temporal position of replaced noise, headphone listening or free field listening, and the listeners’ knowledge of the phenomenon. The results showed that the accuracy of the noise location differed between the positions of replaced noise in the melody or within a beat. The perceptual restoration occurred not only in a headphone listening but also in a free-field listening. It was revealed that the accuracy of noise localization elevated when the listeners knew the stimulus construction, but it was still lower than that of a blank. It was also confirmed that a missing sound could be restored perceptually, not only in a melodic sequence but also in a simple sequence such as scale.
