These three mean showing good judgment, but focus differs. Sound emphasizes strong, flawless logic in arguments or advice. Reasonable emphasizes fairness, for demands or prices that are not excessive. Sensible emphasizes down-to-earth practicality in everyday decisions, opposite to foolish behavior. Not compared: sound's noise meaning.

这三个词都表示“基于良好判断力、合乎情理”，但语气和使用场合不同：sound 强调逻辑严密、有根据；reasonable 强调公平、不过分；sensible 强调务实、符合常识。这里不比较 sound 的“声音”“结构牢固”或“睡得香”等其他意思。
