- Understanding aviation noise
- Improving impact management
ANIMA research suggests that noise mitigation efforts should focus directly on annoyance outcomes for daytime and aircraft noise-induced impairment of sleep quality during nighttime, in addition to reducing noise exposure. For such efforts to be effective, the full suite of acoustic contributions and non-acoustic factors associated with aircraft noise responses must be addressed. The ANIMA project encourages a more comprehensive approach both in the design and evaluation of noise management interventions and in assessing the long-term consequences arising from noise exposure.
ANIMA 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, homeownership, relationship with authorities, perceived predictability, etc.)
Based on the above-mentioned factors, ANIMA developed a set of recommendations for noise management strategies –how aviation actors should design communication and engagement processes that are likely to influence the non-acoustic factors contributing to noise annoyance.
The overview undertaken by ANIMA researchers acknowledges that some non-acoustic factors will not be amenable to influence (e.g. the individual sensitivity to noise, the age of an affected person). However, it may be possible to address others (trust, fairness and attitude 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 and residents directed at the noise management process. In other words, meaningful engagement on noise matters that affect local communities is imperative.
