tonal noise该理解为什么噪声或者如何翻译成什么?
如题,谢谢! tonal noise我理解为噪声的峰值感,心理声学有tonality这个指标来衡量。 Tonal NoiseNoise with distinct tones, for example, noise from fans, compressors, or saws, is generally far more annoying than other types of noise. This annoyance factor is not taken into account in a broadband measurement. A spectral analysis may be needed to assess annoyance.
我查到的,还是想不出这个噪声到底该叫啥 不知道是不是叫纯频噪声! 有音调特性的噪声?
联想到噪声谱图,应该是那种连续谱种存在明显线谱的噪声

调式噪声? 这个声品质评价的一个术语,表示噪声对人心理的烦恼影响度 What Is Tonal Noise?Tonal noise is commonly referred to as discrete frequency noise and is characterized by spectral tones that are pure tone in nature. Pure tones are wave forms that occur at a single frequency. Tonal noise is generated by rotating equipment at a predictable frequency relating to the rotational speed of the shaft and the number of compressor vanes, fan blades, engine pistons, gear teeth, etc. The fundamental tone (F) may also manifest itself at progressively lower intensity levels at integer harmonic multiples (2F, 3F, etc.). Tolerance levels for tonal noise are generally at a lower threshold.
纯音 这个在风扇噪声里面,通常翻译为离散单音,就是通常所说的基频BPF,与此相对应的,还有就是其谐频。
