Property in the vicinity of Perth Airport may be exposed to aircraft noise which can affect individuals in different ways. It is important that aircraft noise impacts are considered and understood when making appropriate property and lifestyle decisions. Perth Airport prepares N65 noise contours which describe the number of aircraft events greater than 65 decibels that can be expected over an average day.
Perth Airport prepares the N65 noise contour map which describes the number of aircraft events greater than 65 decibels that can be expected over an average day. This measure is closer to how a person typically perceives noise.
It is widely recognised that an outdoor sound level of 65 decibels corresponds to an indoor noise level of approximately 55 decibels indoors with the windows open. This is considered to be the approximate sound level at which conversation and other indoor activities can generally be disturbed.
It is important to note, that the N65 noise contour map represents an average day and not a typical day. On a typical day, more events than the N65 noise contour map suggests may be experienced. Additionally, the N65 noise contours reflect the expected long term airfield layout including construction of a new runway.
