Using mobile application to assess quality of acoustic and visual environment in relationship with aircraft noise
* Presenting author
Aircraft noise annoyance has been studied for more than 50 years, asking people to rate their annoyance on a unidimensional scale. The importance of non-acoustic factors shows that a more global approach could help to understand how people perceive their acoustic environment. Inspired by the soundscape studies, and in the frame of the ANIMA European project on the impact of aviation noise, an Experience Sampling Method with signal-contingent sampling is chosen to question people in their daily live about the quality of their acoustic and visual environment, and not on the annoyance. A dedicated mobile application is developed, which collects data each hour of a day (night periods are excluded).The experiment lasts two or three weeks depending on the number of notifications per day the participant found acceptable. After the notification, participants are asked to record acoustic measurements (third octave bands, each second during one minute). After the questionnaire, participants are asked to take a picture of the environment. Summary questionnaires are filled at the end of each week, and a global questionnaire is filled at the end of the experiment. This paper focuses on a pilot study whose aim is to evaluate the acceptability of the method by participants.
