语域：formal 常见场景：formal writing、engineering/structural assessment、financial analysis 该词作名词时多用于正式或书面语境，表示状态或想法的健全、稳固；比较常见于工程评估、财务分析或学术讨论。日常随意口语中通常较少直接使用这个名词，更常用形容词 sound 或短语 in good condition。
以上各词与 soundness 都以 -ness 结尾，后缀读音为 /nəs/（或 /nɪs/），但它们重音所在元音各不相同，因此与 soundness /ˈsaʊndnɪs/ 并不押韵。注意：拼写看似相近的 sound /saʊnd/ 和 sounding /ˈsaʊndɪŋ/，发音与 soundness 不同，不要混淆。
