悄然无声

wǒ ràng tā shàng chuáng shuì jiào hòu tā jiù qiāo rán wú shēng le

我让她上床睡觉后，她就悄然无声了。

There wasn't a peep out of her after I put her to bed.

fáng zi li sì hū qiāo rán wú shēng ān jìng de hǎo xiàng wú rén jū zhù

房子里似乎悄然无声，安静得好像无人居住。

The house seemed muted, hushed as if it had been deserted.
