The analysis of sounds requires attentional resources from the perceiver. As these resources are limited, stimuli that are irrelevant to the task in which the subject is engaged are filtered out in order to be attenuated. While this filtering helps to avoid distraction, it can also lead to ignoring stimuli that should be responded to. This phenomenon is called "attentional deafness".
Our aim was to clarify the conditions under which attentional deafness occurs and the conditions providing a countermeasure to this phenomenon. To this end, two experiments were conducted. The first consisted of a double-task of sound detection during the performance of a main task that was more or less demanding on attentional resources. It did not reveal attentional deafness but allowed the development of a second experiment carried out online involving a higher demand for attentional resources. The protocol implemented generated attentional deafness and made it possible to observe that the addition of amplitude modulations (roughness) to the alarm sound did not reduce the level of attentional deafness. Instead, the latter was reduced when the alarm sound shared its position with another sound that was the target of our attention."
