Examination of the Causal Relationship between Aircraft Noise Exposure, Noise Annoyance and Diagnoses of Depression Using Structural Equation Modelling
* Presenting author
Environmental noise is ubiquitous in daily life and a massive environmental burden, though the effects of transportation noise on mental illnesses are sparsely investigated to date. The recently published WHO review on the impact of transportation noise on quality of life and mental health shows inconsistent findings. Noise annoyance, as an approved psychological stress response to noise, is identified as one of the health impacts of environmental noise. There is some evidence that the impact of noise on health is at least partly mediated by noise annoyance. A reanalysis of data is conducted using data from the socio-acoustical longitudinal survey NORAH (Noise-Related Annoyance, Cognition, and Health) that has been performed mainly at Frankfurt Airport (and three other airports) in Germany from 2011 to 2013. Residents older than 18 and living in the 40 dB-noise contour around Frankfurt Airport were randomly selected to participate in the study. Telephone interviews assessing diagnosed depressions and aircraft noise annoyance among others were conducted annually from 2011 to 2013. Aircraft sound levels were calculated for the exact address of every participant.The present work is an approach to examine the causal relationship between noise exposure, noise annoyance and diagnoses of depression using structural equation modelling.
