语音接收阈值进行了测量与稳定和调幅噪声掩蔽处理的信号包含变量的时间精细结构（TFS）的信息。受试者受益于TFS信息的调制比稳定掩蔽。对于这两个掩蔽，TFS信息增加到548 Hz提高了性能，虽然改善是更大的调制掩蔽。在较高频率处添加TFS信息进一步改进了仅针对调制掩蔽的性能。这些结果是一致的想法，即TFS信息是重要的，在一个起伏的掩蔽音的下降听。
Speech reception thresholds were measured with steady and amplitude-modulated noise maskers for signals processed to contain variable amounts of temporal fine structure (TFS) information. Subjects benefited more from TFS information for the modulated than for the steady masker. For both maskers, addition of TFS information up to 548 Hz improved performance, though the improvement was greater for the modulated masker. The addition of TFS information at higher frequencies improved performance further for the modulated masker only. These results are consistent with the idea that TFS information is important for listening in the dips of a fluctuating masker.
