Hey OP - nobody in either of your threads is suggesting the right answer, which is to contact the city of OP to determine what the law is, whether it's being violated, and how you pursue a complaint if it is.
You might start by examining the OP city code.
I think parts E and F on that page may apply to your situation, but it may eventually come down to the exact level of noise (in decibels) - so you may want to measure the noise level at your window first with a cheap decibel meter from Amazon, so you can have an idea compared to the code levels in Part A.
