BK网站上有介绍的。一查就好
Investigation of Tonal Noise
Noise can be described as tonal if it contains a noticeable or discrete, continuous note. This includes noises such as hums, hisses, screeches, drones, etc. and any such subjective description is open to discussion and contradiction when reported.
简单的说，如果噪声是在频谱上是一段段分布的，就叫做tonal noise.
翻译成“纯音“不确切把。个人觉得叫音调噪声比较好。:-)
