New ISO Standard for reducing noise near airports

Acoustics – Unattended monitoring of aircraft sound in the vicinity of airports ISO 20906:2009 has been introduced to help regulators, professionals, and researchers to reduce noise near airports. This new Standard complements the existing New Zealand Standard Airport noise management and land use planning NZS 6805:1992, which was developed to ensure that people living close to an airport are properly protected from the effects of aircraft noise, while also recognising the need to be able to operate an airport efficiently.

NZS 6805:1992 establishes maximum levels of exposure to aircraft noise around airports for the protection of community health and amenity values. It is a guide for territorial authorities wishing to include appropriate land-use controls in their district plans under the Resource Management Act 1991.

ISO 20906:2009 will be useful to airport operators who are required to install and maintain sound-monitoring equipment around airports, and to report on the results of their monitoring.

ISO 20906:2009 specifications include:

  • the typical application for a permanently installed sound-monitoring system around an airport
  • performance specifications for instruments and requirements for their unattended installation and operation, to determine continuously monitored sound pressure levels of aircraft sound at selected locations
  • requirements for monitoring the sound of aircraft operations at an airport
  • requirements for data to be reported and frequency of publication of reports
  • a procedure for determining the expanded uncertainty of the reported data in accordance with Uncertainty of measurement – Part 3: Guide to the expression of uncertainty in measurement (GUM:1995) ISO/IEC Guide 98-3.
