What does ○○に透けた mean in this sentence?


Listening to [a song](https://soundcloud.com/nakano4/sizuk), I heard these
lyrics:

> はにかんだ声に透けた空はもうここにないのさ

This whole sentence is just a bit odd, but especially so because I'm not sure
how to handle に + 透ける. Would something like "dissolved into" be appropriate?
(e.g. "The sky, dissolved into the sound of a shy voice, isn't here anymore")




AがBに透ける means "A is vaguely visible/felt through B". Commonly used in the form
of AがBに透けて見える.

>   * 肩ひもがシャツに透けている。  
>  Shoulder straps are vaguely visible though the shirt.
>   * 穏やかな声に透けて見える悪意  
>  evil intention that can be felt through his gentle voice
>

So the line basically says this person was somehow feeling/seeing the sky
through her coy voice. This is still a highly poetic and unrealistic
expression, but he was even seeing God in the previous lines, after all :)

**EDIT:** @user4092's interpretation ("the sky that became transparent due to
the voice") is possible, at least grammatically. But in the previous part of
the song, this guy was clearly seeing/feeling God between clouds. Judging from
the structure of the song, it's natural to think something similar is
happening in this part, too.
