Spectral weights in octave-frequency bands from 0.25 to 4 kHz were estimated for speech-in-noise recognition using two sentence materials (i.e., the IEEE and AzBio sentences). The masking noise was either unmodulated or sinusoidally amplitude-modulated at 8 Hz. The estimated spectral weights did not vary significantly across two test sessions and were similar for the two sentence materials. Amplitude-modulating the masker increased the weight at 2 kHz and decreased the weight at 0.25 kHz, which may support an upward shift in spectral weights for temporally fluctuating maskers.
使用两种句子材料（即 IEEE 和 AzBio 句子），在 0.25 到 4 kHz 的倍频程频段中估计了语音噪声识别的谱权重。掩蔽噪声要么是非调制的，要么是以 8 Hz 的正弦幅度调制的。在两个测试会话中，估计的谱权重没有显著变化，并且对于两种句子材料是相似的。调制掩蔽器的幅度增加了 2 kHz 的权重，降低了 0.25 kHz 的权重，这可能支持了对时变掩蔽器的谱权重的向上移位。
