Helicopters and other aircraft should be prohibited from flying low over residential neighborhoods during nighttime hours, such as between 10 PM and 6 AM, except during emergencies or major news events. More precisely, aircraft should be prohibited from causing noises louder than a certain decibel level, such as 50 decibels, on the ground in residential neighborhoods during the restricted hours. Areas around airports could be zoned for higher noise levels, if required and approved through the normal channels.
