Detection of high-frequency energy changes in sustained vowels produced by singers.

摘要: The human voice spectrum above 5 kHz receives little attention. However, there are reasons to believe that this high-frequency energy (HFE) may play a role in perceived quality of singing and speech. To fulfill role, differences HFE must first be detectable. determine ability detect HFE, the levels 8- 16-kHz center-frequency octave bands were individually attenuated sustained vowel sounds produced by singers presented listeners. Relatively small changes fact detectable, suggesting frequency range potentially contributes perception especially voice. Detection was greater 8-kHz than varied with band level.
