Human subjects overestimate the change of rising intensity sounds compared with falling intensity sounds. Rising sound intensity has therefore been proposed to be an intrinsic warning cue. In order to test this hypothesis, we presented rising, falling, and constant intensity sounds to healthy humans and gathered psychophysiological and behavioral responses. Brain activity was measured using event-related functional magnetic resonance imaging. We found that rising compared with falling sound…

Rhesus monkeys (Macaca mulatta) hear rising frequency sounds as looming.
A head-turning assay and a preferential-looking paradigm revealed that monkeys show an attentional bias toward rising versus falling frequency sounds and link the former to visual looming signals, suggesting that monkeys hear a rising frequency sound as a looming sound source even though, in the real world, no such link exists.
Looming sounds as warning signals: the function of motion cues.
Neural Mechanisms Underlying the Auditory Looming Bias
The results indicate the promoted top-down projection but at time points slightly preceding the motion onset and thus considered to reflect a bias driven by anticipation, as well as a bottom-up bias along the dorsal auditory pathway directed toward the prefrontal cortex.
Embodied auditory perception: the emotional impact of approaching and receding sound sources.
The results of this study suggest that approaching unpleasant sound sources evoke more intense emotional responses in listeners than receding ones, whereas such an effect of perceived sound motion does not exist for pleasant or neutral sound sources.
Rapid Ocular Responses Are Modulated by Bottom-up-Driven Auditory Salience
It is shown that a reliable salience scale can be obtained from crowd-sourcing, and that a salience ranking obtained from online raters correlated robustly with the superior colliculus-mediated ocular freezing response, microsaccadic inhibition (MSI), measured in naive, passively listening human participants.
Exposure to arousal-inducing sounds facilitates visual search
It is suggested that arousal induced by sounds can facilitate attention in a subsequent visual search, and this novel finding provides support for the alerting function of the auditory system by showing an auditory-phasic alerting effect in visual attention.
The Contribution of Sound Intensity in Vocal Emotion Perception: Behavioral and Electrophysiological Evidence
Though it cannot categorically affect emotionality conveyed in emotional prosodies, sound intensity contributes to emotional significance quantitatively, implying that sound intensity should not simply be taken as a control parameter and its unique role needs to be specified in vocal emotion studies.

Auditory perception of laughing and crying activates human amygdala regardless of attentional state.
An Adaptive Bias in the Perception of Looming Auditory Motion
Rising acoustic intensity can indicate movement of a sound source toward a listener. Perceptual overestimation of intensity change could provide a selective advantage by indicating that the source is

Presentation modality influences behavioral measures of alerting, orienting, and executive control
Reaction-time measures of executive control were of a similar magnitude and significantly correlated, suggesting that executive control might be a supramodal resource and spatial-orienting benefits were obtained only in the visual task.
