We collect noise and operational data from five noise monitors (Environmental Monitoring Unit, EMU) around Melbourne Airport. Noise monitors are listed below according to their location.

Access monthly data on our Melbourne noise monitoring reports page.

BULLA (EMU 2)

Captures arrivals to Melbourne Runway 16 and departures from Melbourne Runway 34.

Detects more events than the other noise monitor locations due to its proximity to the airport.
The pattern of aircraft noise events recorded reflects the seasonal trends in arrivals to Runway 16, with more events recorded in summer than in winter.

ESSENDON (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.

COOLAROO (EMU 6)

Captures arrivals to Melbourne Runway 27.

While the pattern of noise events recorded reflects the seasonal trend for arrivals to Runway 27 the correlation is not precise as there are some parts of the year where for noise abatement purposes, Runway 27 is used more for departures than for arrivals. Departures from Runway 27 do not fly over this monitor.

KEILOR DOWNS (EMU 9)

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)

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.

THOMASTOWN (EMU 11)

Captures arrivals to Melbourne Runway 27.

The pattern of aircraft noise events recorded reflects the seasonal trend for arrivals to Runway 27, with more events recorded in winter than in summer. As a result the trend for this monitor mirrors that of Coolaroo monitor.
