Community noise effects in general and noise annoyance in particular are mostly studied by relating them to exposure through blind statistical analyses of large datasets. This paper reports on a specific part of a quite different approach. using mathematical simulation of basic perception and psychophysical mechanisms for a large synthetic population. Insight is sought into the mechanisms underlying the emergence of noise effects. This is achieved by comparing–in a phenomenological way–the statistics of the data gathered from the simulated synthetic population in that of the real population. This paper focuses on modeling the role of attention. Attention could play a role in two distinct aspects of the process: firstly, attention can be drawn away from other tasks by the environmental sound or tasks requiring sustained attention can suppress the noticing of the environmental sound; secondly, attention can jump between sounds in multisource sonic environments. In modeling this dual role of attention, care must be taken to simplify existing knowledge on theses aspects of perception in such a way that the model can be used to study long exposure times and large populations. Such modeling may support the assessment of real life situation where multiple environmental sounds interfere and cause noise annoyance. Example simulations involving exposure to railway noise, road traffic noise, and natural sound produced by the individual's own activity show the influence of attention on the model outcome.
