"The aim of this study was to assess the impact of a wind farm on individuals by means of an audio-visual methodology that tried to simulate biologically plausible individual–environment interactions. To disentangle the effects of auditory and visual components on cognitive. performances and subjective evaluations, unimodal (Audio or Video) and bimodal (Audio ? Video) approaches were compared. Participants were assigned to three experimental conditions that reproduced a wind farm by means of an immersive virtual reality system: bimodal condition, reproducing scenarios with both acoustic and visual stimuli; unimodal visual condition, with only visual stimuli; unimodal auditory condition, with only auditory stimuli.. While immersed in the virtual scenarios, participants performed. tasks assessing verbal fluency, short-term verbal memory, backward counting, and distance estimations. (egocentric: how far is the turbine from you?; allocentric: how far is the turbine from the target?). Afterwards, participants reported their degree of visual and noise annoyance.. The results revealed that the presence of a visual scenario as compared to the only availability of auditory stimuli may exert a negative effect on resource-demanding cognitive tasks but a positive effect on perceived noise. annoyance. This supports the idea that humans perceive the environment holistically and that auditory and visual features are processed in close interaction."
