I live on Long Island, New York and have a problem with small aircraft. ?

Every day, two small single engine planes circle over my house for a few hours- disappear for about half an hour and then come back and repeat the circling. This goes on for the whole day - 7:30 AM to 7:30 PM. It is noisy and nerve-wracking. Is there anything I can do? Where can I issue a complaint? I can't believe that these pilots don't think they are ruining the quality of life for the area they impact. Any pertinent input greatly appreciated.
