10名受试者被要求产生八度判断，即标准刺激上一个八度，一个下一个八度，带有低通和高通噪声以及正弦的频带。例如，给出一个特定的低通噪声频段作为标准，受试者调整了第二个低通噪声频段的截止频率，使其音调比标准的音高高出1oct。结果表明，噪声的频带有一个基音，且基音与截止频率相关。对于低通噪声，在80~10000 Hz的截止频率范围内，音调与截止频率之间似乎存在相对线性的关系，而对于高通噪声，线性关系仅在600~10000 Hz的有限频率范围内成立。这两种噪声刺激的音调都在10 kHz以上退化，可能是因为耳机反应有限和听力阈值上升所致。更难解释的是高通噪声在低截止频率下的静态和模糊音调。文中还讨论了几种机制。
Ten subjects were asked to produce octave judgments, i.e., one octave above and one octave below a standard stimulus, with bands of low‐pass and high‐pass noise as well as sinusoids. For example, given a specific low‐pass noise band as a standard, subjects adjusted the cutoff frequency of a second low‐pass noise band so that its pitch was 1 oct above that of the standard. Results indicate that bands of noise have a pitch and that the pitch is correlated with cutoff frequency. For low‐pass noise, there seemed to be a relatively linear relation between pitch and cutoff frequency from 80‐ to 10 000‐Hz cutoff, whereas the linear relation for high‐pass noise holds only for a restricted frequency range, 600–10 000 Hz. The pitch of both types of noise stimuli degenerates above 10 kHz, possibly because of limited earphone response and a rising threshold of hearing. More difficult to explain is the static and vague pitch of high‐pass noise at low cutoff frequencies. A discussion of several mechanisms is included.
