What should I do about this neighbor noise dilemma?

My summer time neighbors have a pool and have been quite noisy over the years. I’ve objected at times and we’re in a fairly decent place with each other. Recently they put up wind chimes on a tree near my bedroom window. It’s tolerable with the window closed but I fear it will be sleep destroying come summer.

I hate appearing like the cranky old lady next door but is it valid for me to ask them to move it?
