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 voice in singing and speech. To fulfill this role, differences in HFE must first be detectable. To determine human ability to detect differences in HFE, the levels of the 8- and 16-kHz center-frequency octave bands were individually attenuated in sustained vowel sounds produced by singers and presented to listeners. Relatively small changes in HFE were in fact detectable, suggesting that this frequency range potentially contributes to the perception of especially the singing voice. Detection ability was greater in the 8-kHz octave than in the 16-kHz octave and varied with band energy level.
人声音谱中 5 kHz 以上的频段很少受到关注。然而,有理由相信,这种高频能量(HFE)可能在歌唱和言语的声音感知质量中发挥作用。要发挥这种作用,首先必须能够检测到 HFE 的差异。为了确定人类检测 HFE 差异的能力,我们分别衰减了歌手发出的持续元音中 8 赫兹和 16 赫兹中心频率倍频程频段的水平,并将其呈现给听众。实际上,HFE 的相对较小变化是可以检测到的,这表明该频率范围可能有助于感知特别是歌唱声音。在 8 赫兹倍频程中,检测能力大于在 16 赫兹倍频程中,并且随频带能量水平而变化。
