How to get associauion to stop enerynight noise

Bought My twin Patio new in 1974,Perhaps one of the first. Latest owner bought as a rental,& the Place has deteriorated badly. Problem started when a Truck pulled in and blocked My getting out of My Garage,as the width of the driveway is 20,3" wide. The Man did not live there,but stated that I previously asked Him not to let His dog poop on My lawn,which was a noted dumping ground a few years ago. At first He refused to Move ,until I went to call the Police. The Police interviewer,with whom I visited told Me never to knock on their door for any Nuisances,but to call them,which really made matters worse.

Then came the Music,to which I called as requested,but,by the time they saw the Police arrive the Music was turned off,& the Lady owner became hostile,& cursed Me out for asking that Her Sons Please turn the sound down. She called Me the word F*** a half dozen times before I hung up.

The Music has ended,but for the past couple of Months,there is a humming noise heard nightly,that reverberates other noises to My two Bedrooms,that make it impossible to sleep.
The Police,& Homeowners association,& owner have washed their hands.so the noise,& sound which I have recorded,& have Two witnesses,who also spoke to the Police,who stated,The noise was not load enough. Am 77 yrs old,with 45 percent of My Heart left,& wake up at time with chest Pains,& take Nitro Pills. Also treated for a lung tube blockage,& use two inhalers. Am not looking for sympathy for the last part.but for an idea to stop this existing problem.

Note; Visited My son in another state for a Week,& was driven to the Airport,by a Friend,and My car was stored in the garage,arrived after 9pm,& apparently was not noted for two days,then it all started again. Any help or ideas would be appreciated Thanks John
