"Ruhe ist schön."

[richardlevay]

is this not the idiomatic equivalent "silence is golden"

[mabersold]

I could not understand the voice saying "Ruhe."

[wataya]

sounds fine to me

[PlentyForever]

I had the same issue. Should we not pronounce the "r" at the beginning of words with an "ru" sound, or something like that?

Isn't the word "pretty" more of "hübsch"?

I've never heard of the word "pretty" used in this context. It is usually used to describe appearance and not intangible things like silence.
