All of these strategies are used to reduce aircraft noise in suburban neighbourhoods. Technological improvements have led to quieter aircraft engines, planning airport locations and routes away from residential areas helps to reduce noise exposure, implementing noise abatement operational procedures such as adjusting the timing and altitude of flights can also help, and restricting operations at night can reduce disturbance to sleep. All of these strategies are used in combination to minimize the impact of aircraft noise on communities.
