Bell 407 (N660AE)

As anyone knows who has been around these helicopters, they are extremely loud. Air Evac Lifeteam pilots are harassing my property. I have many, many files, starting in 2018, of different Air Evacs flying low over my property, my house, or my deer. I know why but cannot explain without fear of being sued. This helicopter flew low and close to my driveway this morning, Feb. 14, 2020, at 10:20 a.m. There is no reason for this aircraft to be where it was, at the height that it was (no flight plan.) This is a private company supposedly operating a medical service and they should be required to file flight plans, follow FAA regulations, and list information about their company on their registration. I have complained to the management of ERV and TXDOT Aviation but have not received any response.
