ANIMA research suggests that noise mitigation efforts should focus on annoyance outcomes for day time and aircraft noise induced impairment of sleep quality during night time in addition to reducing noise exposure. For such efforts to be effective, the full suite of acoustic contributions and non-acoustic factors associated with responses to aircraft noise must be addressed. To date, management interventions and impact studies have only partially addressed these contributions. The ANIMA project encourages a more comprehensive approach both in the design and evaluation of noise interventions, and in the assessment of the long-term consequences arising from noise exposure.
ANIMA analysis suggests that addressing annoyance and sleep disturbance directly should be central to effective noise impact management. Annoyance is affected by acoustic variables (the noise itself), as well as non-acoustic factors (e.g. personal noise sensitivity, perceived procedural fairness, coping ability, home ownership, relationship with authorities, perceived predictability, etc.) and the combination of the two.
Based on the above factors, ANIMA elaborated a set of recommendations for noise management strategies. The review performed by the ANIMA researchers acknowledges that some non-acoustic factors will not be amendable to influence (e.g. the individual sensitivity to noise, the age of an affected person), but it may be possible to address others (trust, fairness and attitudes towards the sources of the noise) through management interventions and thereby influence the extent of annoyance. These factors can be best addressed through communication and engagement between airports, authorities, independent research institutions and residents, directed at the noise management process. In other words, through meaningful engagement on noise matters that affect local communities.
In the upcoming period, the ANIMA project is working on delivering more results, such as:
- a critical review of the implementation of the Balanced Approach across EU member states
- an overview of the use of noise footprints for different operational, planning and communication purposes
- recommendations for the use of tools and metrics to allow environmental performance interdependencies to be quantified and illustrated
- a critical review of policy and practice in other noise-affected sectors
- an assessment of the wider impact of noise mitigation efforts on communities
- pilot study on novel-land use planning approaches
- mobile application – the application is currently being tested.
Where to see ANIMA next: Join us at the 25th AIAA/CEAS Aeroacoustics Conference (Aeroacoustics 2019), between 20 and 24 May 2019. ANIMA will have a stand showcasing current research efforts on aviation noise at European level.
