通过绝对幅度估计（AME）研究了噪声-音调复合体的整体感知幅度（响度、烦恼和噪声）与音调在频谱内的位置之间的关系。250、1000、2000和3000 Hz的单音被添加到低通和高通噪声中。与噪音相反，响度和烦恼增长行为取决于添加音调的频率与噪音的频谱形状之间的关系。以噪声为中心的音调产生非单调的响度和烦恼增长函数;添加到裙部的音调产生幂函数。当音调位于频谱内时，测量的指数在音调噪声比上是不变的，但当它们被添加到裙部时则不是。此外，对于大致相同的总SPL的复合，音调的位置决定了响度（或烦恼）和音调噪声比之间的函数关系。虽然一个音调校正烦恼是必要的某些噪声音调配置，没有一个建议的计算程序认为所有的变量相关的感知烦恼的音调成分。在很大程度上，由噪声和音调的同时呈现所产生的复杂的听觉交互可以解释所观察到的效果。
The relation between overall perceived magnitude (loudness, annoyance, and noisiness) of noise-tone complexes and the location of the tone within the spectrum was investigated by absolute magnitude estimation (AME). Single tones at 250, 1000, 2000, and 3000 Hz were added to low-and high-pass noises. In contrast to noisiness, loudness and annoyance growth behavior depends on the relationship between the frequency of the added tone and the spectral shape of the noise. Tones centered in noise produce nonmonotonic loudness and annoyance growth functions; those added to the skirt produce power functions. The measured exponents are invariant across tone-to-noise ratio when the tones are positioned within the spectrum, but not when they are added to the skirt. Moreover, for complexes at approximately the same overall SPL, the tone's position determines the functional relationship between loudness (or annoyance) and tone-to-noise ratio. Although a tone correction for annoyance is warranted for certain noise-tone configurations, none of the proposed calculation procedures considers all the variables relevant to perceived annoyance of tonal components. To a large extent, complex auditory interactions generated by the simultaneous presentation of noise and tone can account for the observed effects.
