具有正 (m+) 和负 (m-) 施罗德相位的色调复合体在掩蔽效率方面表现出巨大差异。这项研究调查了不同的相位特性是否也会影响响度。 m+ 和 m- 复合体之间的响度匹配被测量为以下函数:(1) 正常听力和听力受损受试者中不同频带的基频 (f0),以及 (2) 正常听力受试者中的强度水平。在听力正常的受试者中,在相同响度点,m+刺激的水平比相应的m-刺激的水平高出10dB。 20 至 60 dB SL 之间的响度差异最大。在听力受损的听众中,差异减小,表明主动耳蜗机制的相关性。 m+ 和 m- 刺激与常见噪声参考(实验 3)的响度匹配显示出作为 f0 函数的差异,这与实验 1 的直接比较一致,并且还表明该效果主要是由于 m+ 的特定内部处理造成的。研究结果与有关掩蔽效率的研究大致一致,并且可能无法用当前的响度模型来解释,支持在未来的响度模型中纳入更真实的耳蜗模拟的需要。
Tone complexes with positive (m+) and negative (m-) Schroeder phase show large differences in masking efficiency. This study investigated whether the different phase characteristics also affect loudness. Loudness matches between m+ and m- complexes were measured as a function of (1) the fundamental frequency (f0) for different frequency bands in normal-hearing and hearing-impaired subjects, and (2) intensity level in normal-hearing subjects. In normal-hearing subjects, the level of the m+ stimulus was up to 10 dB higher than that of the corresponding m- stimulus at the point of equal loudness. The largest differences in loudness were found for levels between 20 and 60 dB SL. In hearing-impaired listeners, the difference was reduced, indicating the relevance of active cochlear mechanisms. Loudness matches of m+ and m- stimuli to a common noise reference (experiment 3) showed differences as a function of f0 that were in line with direct comparisons from experiment 1 and indicated additionally that the effect is mainly due to the specific internal processing of m+. The findings are roughly consistent with studies pertaining to masking efficiency and can probably not be explained by current loudness models, supporting the need for incorporating more realistic cochlea simulations in future loudness models.
