Learner notes
Memory Tip
拆开看：hyper（超级）+ sonic（音速）→ 比音速还快很多，记住“超级音速”就是高超音速。
Context & Register
语域：formal 常见场景：航空工程、航天技术、军事防务 该词多用于正式的科技、工程或军事语境，表示速度超过5倍音速；日常口语中很少使用。
Pronunciation & Spelling
这些 -sonic 结尾的词重音都在 -son-，读作 /ˈsɒnɪk/，与 hypersonic 押韵。注意 hypersonic 的 hyper- 读 /ˌhaɪpə-/，别与 hypertonic /ˌhaɪpəˈtɒnɪk/（高渗的）混淆——它虽形似，但 -tonic 读 /tɒnɪk/，发音不同。
