Aircraft noise is probably the foremost concern of local communities located close to (and even at some distance from) airports. The competent management of noise annoyance issues is key to securing future capacity for an airport.
About Noise Management
The general public and local authorities expect airports to take measures to reduce and mitigate
noise impacts around the airport and also increasingly along the flight paths around it.
To answer these concerns, Envisa provides solutions to help airports manage their noise annoyance
issues by evaluating the current noise impacts, elaborating noise reduction plans, and communicating
on noise issues with local communities and public authorities.
Good airport noise management is covered by ICAO guidance Doc 9829/AN/451 Guidance on the Balanced Approach to Noise Management. This sets out the four pillars of noise management as:
- Reduction of noise at source
- Land use planning and Management
- Noise Abatement Operational Procedures
- Operating restrictions; not applying operating restrictions as a first resort, but only after consideration of the other measures of the Balanced Approach
The guidance recommends that any steps within these measures should be based on detailed noise studies and should be appropriate to the nature and scale of any noise problem and to be carried out on an airport-by-airport basis.
Envisa has extensive experience of conducting technical noise analysis using internationally recognised and approved models and methodologies.
The guidance also sets out the need for transparency, consultation, community engagement and published planning. Indeed, we have found that without adequate engagement and collaboration with stakeholders any airport can only apply a very limited noise management plan covering limited areas with the four balanced approach pillars.
