<br>abstract = {Sound identity defines a hierarchy of auditory perception, influencing how sounds in dynamic scenes are prioritized. The current study explores a perceptual continuum that distinguishes between foreground and background sounds. First, a novel scoring mechanism is introduced to quantify the perceived importance of individual sound events in complex auditory scenes. The scores, along with statistics from the behavioral responses, highlight privileged treatment toward specific sound classes. Furthermore, hierarchical clustering exposes perceptual biases tied to sound classes, delineating a continuum from foreground to background sounds. Behavioral responses, auditory salience, and pupillometry data validate this distinction, with more pronounced attentional shifts and rapid pupil dilation for foreground sound classes. In contrast, certain behaviors, like the relationship between identification reaction time and perceptual importance remain sound-class-independent. These findings emphasize the dynamic relationship between sound identity and auditory attention, offering a framework for understanding auditory scene analysis. Despite limitations in dataset size and scope, the study advances our understanding of how sound identity shapes perception and contributes to our understanding of the mechanisms governing auditory cognition.},
