A model for the perception of environmental sound based on notice-events

• Anapproach is proposed to shed light on the mechanisms underlyinghuman perception of environmental sound that intrudes in everyday living.Most research on exposure-effect relationships aims at relating overall effectsto overall exposure indicators in an epidemiological fashion, without includingavailable knowledge on the possible underlying mechanisms. Here, it isproposed to start from available knowledge on audition and perceptionto construct a computational framework for the effect of environmentalsound on individuals. Obviously, at the individual level additional mechanisms(inter-sensory, attentional, cognitive, emotional) play a role in the perceptionof environmental sound. As a first step, current knowledge ismade explicit by building a model mimicking some aspects ofhuman auditory perception. This model is grounded in the hypothesisthat long-term perception of environmental sound is determined primarily byshort notice-events. The applicability of the notice-event model is illustratedby simulating a synthetic population exposed to typical Flemish environmentalnoise. From these simulation results, it is demonstrated that thenotice-event model is able to mimic the differences between theannoyance caused by road traffic noise exposure and railway trafficnoise exposure that are also observed empirically in other studiesand thus could provide an explanation for these differences.
