for me, the peace in nature, when it is louder than the unnatural, is where i find the most peace. it is hard to describe, but when you hear it, you know it. it is getting harder and harder to find that peace, so i usually resort to A) finding louder nature (waterfall...), or B) ignoring the sounds and seeking a visual peace.
as much as i like music, if i listen while out camping, it is always with headphones. the idea is to take my mind off the unnatural, but not add to it for others.
at least that is my version of peace while camping. not silence, but nature in ether a visual or full experience.
