Balmoral at Bridlewood

I live in an apartment complex. Recently another apartment in a building across from mine has put up windchime which make noise 24/7. Given the thin walls of my apartment I can hear them from almost anywhere in my apartment. I have tried to get apartment management to do something about it but the refuse to do so and have threatened action if I try to personally contact the residents of the apartment that put up the chimes. What can I do?
