For several years we've run a programme of noise monitoring to get a better understanding of the levels of aircraft noise in the communities surrounding Gatwick Airport.


What is a noise monitor?

A noise monitor provides a method of monitoring and recording noise from both aircraft, and background sources. This allows us to evaluate trends and make comparisons between the noise environments at different locations.

Criteria for the location of new monitors

Because of limited noise monitoring resources we have set out protocol for the decision process on the placement of new monitors. The process and criteria are summarised below:

  1. When deciding where to locate monitors, our main aim is to achieve an equable geographical spread around the airport so that as many communities as possible are covered by the scheme.
  2. We do consider requests to have monitors positioned in specific locations and all such requests should be made to your local Gatwick Consultative Committee (GATCOM) member. If you do not know your GATCOM member your Parish Council will pass on your request.
  3. Is there a noise monitor already in the area? If there is already a monitor close by, then it's unlikely that we'll place another monitor in the locality. 
  4. The map below shows the location of our current and previous noise monitoring sites. 
  5. Has there been a noise monitor previously in the area? If there has been a monitor in the locality or close by within the last three years then it's unlikely that we'll place another monitor in the area so soon.
  6. Is the area regularly overflown by aircraft flying to or from Gatwick Airport? If the answer is no we would not consider a request as the main aim of the scheme is to measure noise from aircraft.

All requests we receive that meet the above criteria will be considered, however the final decision on placement is made the Noise and Track Monitoring Advisory Group (NATMAG), based on recommendations by the Gatwick Noise Monitoring Group (GNMG).

Noise monitor site requirements

If a site you've requested is agreed, then you need to identify a suitable location for the noise monitor. Below is our advice on choosing an appropriate site:

  • A secure site in an open area - typically a back garden of a large house or farm.
  • Open access to the apparatus for the engineer (this would be on a weekly basis and not by appointment).
  • Parking for the engineer within 50 metres of the apparatus as heavy loads may have to be carried to and from the noise monitor.
  • The site must be well away from any sound reflecting surfaces such as walls or fences etc.
  • It should ideally be in a south facing area to allow solar panels to be used.
  • The site should be in a reasonably quiet area away from noisy roads, railway lines or any other noise sources that may interfere with the monitoring of aircraft noise.
  • The site should be over flown by aircraft operating from Gatwick.

Other considerations

We do not place mobile noise monitors in locations in response to the wishes of noise complainants but in conjunction with the GNMG and NATMAG.

We do not provide noise data to individuals from mobile noise monitors, however a summary report on the noise climate at that location will be produced by the airport’s independent acoustic consultants and published on this website. Noise monitors will normally be in place for one year. 

Gatwick Noise Monitoring Group (GNMG).

The GNMG consists of Environmental Health Officers and associated noise professionals from the Local Authorities surrounding Gatwick Airport, the Technical Advisor from the Gatwick Airport Consultative Committee (GATCOM), the Gatwick Airport Flight Team Performance Manager and Gatwick Airport Ltd’s independent acoustic consultants.

Noise and Track Monitoring Advisory Group (NATMAG)

The NATMAG is chaired by Gatwick Airport Ltd with membership drawn from the Department for Transport, National Air Traffic Services, the airline industry, local Environmental Health Officers and appointed members from GATCOM. It oversees the administration of the environmental monitoring systems used by the Flight Performance Team at Gatwick Airport and discusses local issues concerning aircraft noise and track keeping.
