Auditory Looming

AbstractAnimals exhibit innate defense behaviors in response to approaching threats cued by the dynamics of sensory inputs of various modalities. The underlying neural circuits have been mostly studied in the visual system, but remain unclear for other modalities. Here, by utilizing sounds with increasing (vs. decreasing) loudness to mimic looming (vs. receding) objects, we find that looming sounds elicit stereotypical sequential defensive reactions: freezing followed by flight. Both behaviors require the activity of auditory cortex, in particular the sustained type of responses, but are differentially mediated by corticostriatal projections primarily innervating D2 neurons in the tail of the striatum and corticocollicular projections to the superior colliculus, respectively. The behavioral transition from freezing to flight can be attributed to the differential temporal dynamics of the striatal and collicular neurons in their responses to looming sound stimuli. Our results reveal an essential role of the striatum in the innate defense control.

Recent research has suggested that low-level psychoacoustic parameters such as loudness and spectral brightness are correlated with musical chills, a subjective emotional experience accompanied by goosebumps, shivers, and tingling sensations. These relationships may be explained by a vigilance theory of chills, through the process of auditory looming; however, these correlations or theories have never been causally tested. In the current study, participants ( N = 40) listened to five variations (original, low loudness, high loudness, low brightness, high brightness) of an experimental and control piece of chills music, characterized by a crescendo and guitar solo respectively; this qualitative distinction was made based on whether the underlying musical structure of the pieces was or was not capable of engaging auditory looming processes. It was predicted that increases in loudness would result in increased chills frequency across participants, indicated by button presses; brightness was included as an exploratory parameter. Results show that for the experimental piece, increases in loudness resulted in significantly more frequent chills experiences, and increases in brightness significantly reduced the frequency of chills, whereas no effects were found for the control piece. Findings are discussed in terms of vigilance and social bonding theories of chills, and the complex interactions between low-level psychoacoustic properties and higher-level musical structures.

Twenty-four respondents continuously rated the loudness of the first 65 seconds of a Dvořák Slavonic Dance, which was known to vary considerably in loudness. They also rated the same excerpt when the sound file was digitally treated so that (1) the sound pressure level (SPL) was inverted or (2) it was temporally reversed or (3) both 1 and 2. Specifically we wanted to see if acoustic intensity was processed into the percept of loudness primarily using a bottom-up (indifferent to timbral environment and thematic cues) or top-down style (where musical context, such as instrument identity and musical expectation affects the loudness rating). Comparing the different versions (conditions) allowed us to ascertain which style they were likely to be using. A single, six-second region was located as being differentiated across two conditions, where loudness seemed to be increased due to expectation of the instrument and orchestral texture, despite the lower SPL. We named this effect an auditory loudness stroop. A second region was differentiated between the two conditions, but its explanation appears to involve two factors, auditory looming perception and the reversal of stimulus note ramps. The overall conclusion was that the predominant processing style for loudness rating was bottom-up. Implications for further research and application to models of loudness are discussed.
