Noise and Flight Path Monitoring System (NFPMS)

Airservices operates a Noise and Flight Path Monitoring System to collect noise and operational data from twelve noise monitors around Sydney Airport.

Noise monitoring is not conducted to determine compliance with aircraft noise regulations – there is no regulated maximum level for aircraft noise. The relevant regulations are the Air Navigation (Aircraft Noise) Regulations 2018. These regulations require that before an aircraft begins operating in Australia it must meet international noise standards that specify the amount of noise that may be emitted by that type or model of aircraft.  If an aircraft does not pass this certification process, it may not fly in Australia. 

Noise monitoring is conducted to:

  • determine the contribution of aircraft noise to the overall noise that a community is exposed to
  • provide information to the community about aircraft noise and operations
  • help local authorities make informed land use decisions
  • inform estimates of the impact of changes to air traffic control procedures
  • validate noise modelling
  • inform the determination of aircraft noise policy by government and assist in the implementation of legislation.

More information about how the noise monitoring program works is available in the Monitoring Aircraft Noise fact sheet.

You can access monthly noise monitoring data in our interactive Noise monitoring report.

Each of the twelve noise monitors (environmental monitoring units or EMU) has been located to capture noise from specific types of operations as described below.

North

Sydenham (EMU 6)
Captures arrivals to Runway 16 Right and departures off Runway 34 Left. This monitor is closest to the threshold of Runway 16 Right/34 Left. The consistently high number of noise events reflects the high use of the main runway throughout the year.



St Peters (EMU 13)
Main purpose is to capture arrivals to Runway 16 Left, however it can capture movements from Runway 16 Right/34 Left and departures off Runway 34 Right.

This monitor captures many of the same operations as the Annandale monitor and demonstrates the same seasonal pattern. However, being closer to the runway it captures more aircraft noise events.

Annandale (EMU 12)
Main purpose is to capture arrivals to Runway 16 Left, however it can also capture movements from Runway 16 Right/34 Left and departures off Runway 34 Right.
The pattern of aircraft noise events recorded at this monitor reflects the seasonal pattern use of Runway 16 Right, with generally more events recorded in summer than in winter.


Leichhardt (EMU 36)
Captures arrivals to Runway 16 Right.

This monitor is affected by the same operations as Hunters Hill monitor and reflects the seasonal pattern use of Runway 16 Right, with more events captured in summer than in winter.


Hunters Hill (EMU 116)
Captures arrivals to Runway 16 Right.

The number of noise events recorded by this monitor reflects the seasonal pattern use of Runway 16 Right, with more events captured in summer than in winter.

Croydon (EMU 102)
Captures departures off Runway 34 Left.

The number of noise events recorded reflects the seasonal pattern use of Runway 34 Left with more aircraft noise events captured in winter than in summer.

South



Threshold Runway 34 (EMU 1)
Captures departures off Runways 16 Right and 16 Left and arrivals to Runways 34 Left and 34 Right

The number of aircraft noise events captured reflects the pattern of use of Runway 34 Left, with more events generally recorded in winter than in summer.

Kurnell (EMU 101)

Captures arrivals to Runway 34 Right and some arrivals to Runway 34 Left

East

Eastlakes (EMU 99)

Captures arrivals to Runway 25 and departures off Runway 07 and Runway 34 Right.

The pattern of aircraft noise events recorded reflects the seasonal use of Runway 34 Right, with more movements in winter than in summer.


Coogee (EMU 100)

Captures arrivals to Runway 25, departures off Runway 07 and Runway 34R heading to the east and south.

Captures noise from similar operations and reflects the same seasonal pattern to the Eastlakes monitor, however being further east from the airport the number of noise events recorded is smaller.

West




Bexley (EMU 3)

Captures arrivals to Runway 07 and departures off Runway 25.

This monitor is closer to the runway than the Penshurst monitor, therefore it displays the same trends but records more aircraft noise events.

Penshurst (EMU 2)

Captures arrivals to Runway 07 and departures off Runway 25.

Historically at Sydney Airport there are fewer departures off Runway 25 than the other Runways.
