翻译：当我听到那声久违声音时 几乎觉得空气像是凝固了一样 除了他的声音 我只能听到自己的呼吸

When I heard that sound I haven't heard for a long time. I even felt the air was frozen. Besides his voice, I could only hear my own breath.

as i heard the voice that i havent heard in a long time, the air was like frozen to me, i can only hear my won breath other than his voice.

When hearing the voice i haven't heard for ages,i feel the air is nearly solidified. Except for his voice,i can only hear my breath.
