You have this somewhat informal idiom: "a sight for sore eyes":
: a person or thing that you are very glad to see
– After being away from home for so long, my friends and family were a sight for sore eyes.
There are examples which don't involve human beings. Possibly used more often with people, but sometimes used to describe something beautiful and heart-warming, as in a scenery or with nature.
Is there an equivalent or similar idiom for sounds? As in related to the feeling of hearing voice of those people you were away from, the sound of a long forgotten engine, or sounds in nature?
