语域：mixed 常见场景：书面/文学描写、医疗/体检、语音学/语言学 该词在普通书面语中多用于描写低而模糊的声音，如人群的嗡嗡声或流水的潺潺声；在医疗语境中 heart murmur 指心脏杂音，是比较正式的医学术语；在语音学中还可指辅音发音时附带的弱元音。日常口语中表达“小声说话”时通常不用单个 murmur，而会选 mumble、whisper 等词，具体搭配和正式程度需结合场景判断。
与 murmur 真正押韵的是 firmer（/ˈfɜːrmər/）。murder 和 murky 开头有相同的 /mɜːr/ 音，但不完全押韵；mural 拼写相似却读作 /ˈmjʊrəl/，注意区分。summer 只共享末尾音 /mər/，mutter 仅词义相近。
