• Resumen

  • Currently research into the psychological evaluation of noise in daily life is carried out without taking into account the sense of sight. The human senses interact with each other; thus some information coming from one sense can be skipped or ignored in favor of information coming from another sense, leading to completely different reactions or behavior. The aim of this paper is to verify, on the basis of psychophysical experiments, how a human being processes audio-visual information coming from the different environmental noises which can be encountered in daily life. The experiment was divided into three parts: auditory, visual, and audio-visual. In each part of the experiment, the ICBEN scale (0-10) was used to rate the presented stimuli. In the first part only audio stimuli were presented, and subjects were asked to rate their annoyance with the sound. In the second part of the experiment, the participants were asked to rate how pleasant the presented video clips were. Finally, in the last part of the experiment, participants were presented with a compatible and incompatible mix of audio and visual stimuli and asked to rate their annoyance. We found that several audio stimuli were assessed differently, to a significant extent, by listeners after video clips were added to them.
