词源etymology
拉丁语 susurrus（低语、嗡鸣），本身就是拟声——把这个词念出来，嘴里就有那阵风。 双写的 s 和 r，是词义的一部分。
Latin susurrus (a whisper, a hum) — itself onomatopoeic: say the word aloud and the breeze is already in your mouth. The doubled s and r are part of the meaning.
背景the story
名词 susurrus 于 1826 年首证于英语。它的亲戚 susurration 来得早得多——15 世纪就到了， 当时的意思却是「恶意的私语」：流言、谗言。
几百年下来，恶意褪干净了，只剩声音本身：风、树、纸页、人群远处的嗡嗡。 一个从「坏话」慢慢洗白成「白噪音」的词。
The noun susurrus is first attested in English in 1826. Its cousin susurration arrived far earlier — the 15th century — meaning something worse: malicious whispering, rumor.
Over the centuries the malice rinsed out, leaving only the sound: wind, trees, turning pages, the far-off hum of a crowd. A word laundered, slowly, from slander into white noise.

中文有一整套现成的拟声：「沙沙」「簌簌」「窸窣」。 差别在词性：中文这些是拟声词，得趴在别的词上用；susurrus 是个正经名词，能当主语。 「窸窣」是效果，susurrus 是那件东西本身。
Chinese owns a whole set of ready onomatopoeia: 沙沙, 簌簌, 窸窣. The difference is grammatical — those are sound-words that lean on other words, while susurrus is a full noun that can take the subject seat. 窸窣 is the effect; susurrus is the thing itself.

A dictionary word (Merriam-Webster), fine in formal writing, though distinctly bookish — it earns its keep in description and essays. Once per piece, same rule as petrichor.
