An investigation of the perceived effects of tonal components was undertaken to establish a broader data base for quantification and prediction of annoyance of sounds containing added tones. The current study was concerned with two-tone-noise complexes. The stimuli were tone pairs added to a low-pass noise that was attenuated by 5 dB/oct above 600 Hz. Overall perceived magnitude is shown to be a function of the frequency separation (delta F) between the tonal components, tone-to-noise ratio, and the overall SPL of the noise-tone complex. Results obtained with two tones are compared to those obtained in an earlier study with single tones [R. P. Hellman, J. Acoust. Soc. Am. 75, 209-218 (1984)]. The observed effects appear relevant to the rules governing loudness summation across frequency, to measurements of psychoacoustic consonance and roughness, and to the issue of mutual masking among the component stimuli. The implications of the findings in relation to proposed tone-correction procedures are also discussed.
对音调成分的感知效应进行了一项调查，以建立一个更广泛的数据库，用于量化和预测包含附加音调的声音的烦恼度。当前的研究关注双音噪声复合体。刺激是添加到低通噪声中的音调对，该低通噪声在600 Hz以上以5 dB/倍频程衰减。总体感知强度显示为音调成分之间的频率间隔（ΔF）、音噪比以及噪声-音调复合体的总体声压级的函数。将两个音调获得的结果与早期单音调研究[R. P. 赫尔曼，《美国声学学会杂志》75，209 - 218（1984）]中获得的结果进行了比较。观察到的效应似乎与跨频率响度总和的规则、心理声学和谐度和粗糙度的测量以及成分刺激之间的相互掩蔽问题相关。还讨论了这些发现对提议的音调校正程序的影响。
