Essendon Airport

Noise Monitoring

Airservices collects noise and operational data from two noise monitors (Environmental Monitoring Unit, EMU) around Essendon Airport.

ESSENDON (EMU 4)
EMU 4

  • Captures arrivals to Melbourne Runway 34 and arrivals to Essendon Runway 35 and departures off Essendon Runway 17.
  • Seasonal fluctuations in the use of Runway 34 at Melbourne Airport are offset by the opposite fluctuations in the use of Runway 17 at Essendon Airport.

KEILOR EAST (EMU 3)
EMU 3

  • Captures arrivals to Melbourne Runway 34.
  • The pattern of aircraft noise events reflects the seasonal trend for arrivals to Runway 34, with more events recorded in winter than in summer.

Noise monitoring is not conducted to determine compliance with aircraft noise regulations – there is no regulated maximum level for aircraft noise. Rather, aircraft operating in Australia are required to meet noise standards imposed through the Air Navigation (Aircraft Noise) Regulations 1984. These regulations stipulate compliance with international noise standards that apply to the design and production of aircraft, and specify the amount of noise that may be emitted by an aircraft type or model. Aircraft that do not meet these standards are prohibited from engaging in air navigation in Australia unless exceptional circumstances apply. This is administered by the Department of Infrastructure and Regional Development.

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 is available in the Monitoring Aircraft Noise fact sheet.

Explanation of terms used
Information found in the aircraft’s flight plan is combined with noise data from the Noise and Flight Path Monitoring System to produce the tables shown for each location below.
Aircraft Type
Where known, aircraft types are listed by name and notated as either jet (J), turboprop (T), propeller (P), helicopter (H) or unknown (U).

Where the aircraft type is listed as “General Aviation”, this means that the aircraft type or category is not known. This occurs when a detailed flight plan has not been lodged for the flight. This is often the case for training activities.

Operation Type

(A) – Arrival
(D) – Departure
(T) – Operation that departs and arrives at the same airport, including circuits and training flights

Correlated Noise Event (CNE)

A noise event matched to an aircraft operation that flew through the capture zone

LAmax

Maximum sound level in decibels (dB(A))
