Take a look at the sentence again:
To gain attention, Christie has pierced each of her ears eight times on
breezy days, people hear the tinkling sounds of Christie's unique wind
chimes as the jewelry blows in the wind.
Nothing needs to be fixed between chimes and as. People hear the tinkling sounds of Christie's unique wind chimes is a main clause. As the jewelry blows in the wind is a subordinate clause, which must be attached to a main clause. When you connect a subordinate clause to the end of a main clause, you generally need no punctuation.
