澄む: clear air and a clear voice in a quiet hall
Read 澄む through distant mountains visible after rain and a voice in a quiet hall. Distinguish visual clarity from clear sound without adding loud volume, perfect pitch, or a precise viewing distance.
Clear air makes distant mountains visible
澄む (すむ) can describe air becoming clear. 「雨上がりの空気が澄んで、遠くの山まで見えました。」 means “The air cleared after the rain, and we could see the distant mountains.” The clarity of the air is linked to the result of being able to see those mountains.
澄んで describes the air, while 見えました states what became visible. This is not a description of a voice's quality or a report of a precise viewing distance. Keep the stated extent: the distant mountains could be seen.
A clear voice fills the quiet hall
「彼女の澄んだ声が静かな会場に響きました。」 means “Her clear voice filled the quiet hall.” 澄んだ modifies 声. The clarity here concerns the quality of the voice rather than visibility through the air.
The voice filling the hall and the voice being clear present an action and a quality. Do not automatically read 澄んだ声 as high volume or perfect pitch. What is stated is a clear voice sounding in a quiet hall.
Find the sense and the subject involved
The air sentence contains a visual clue: distant mountains could be seen. The voice sentence contains an auditory scene: a voice sounded in a quiet hall. Rather than assigning 澄む to only one sense, identify whether it describes 空気 or 声.
Both sentences involve clarity, but clear visibility and a clear sound are different qualities. A clear voice does not make the mountains more visible, and clear air does not establish a performance's pitch accuracy. Match each subject to the result or action presented with it.
Does 「澄んだ声」 mean that the voice is loud?
Show the answer and why
No. It describes the voice's clear quality. The example places it in a quiet hall but does not judge its volume as high or its pitch as perfect.
