“…Although the precise cortical mechanisms behind this looming bias are not yet clearly understood, parts of the hypothesized networks have been extensively studied. Inferior parietal areas of the cortex (inferior parietal lobule; IPL) have been found crucial for spatial hearing in general ( Majdak, Baumgartner, & Jenny, 2020 ; van der Heijden, Rauschecker, de Gelder, & Formisano, 2019 ) and sound motion processing in particular ( Warren, Zielinski, Green, Rauschecker, & Griffiths, 2002 ). Functional magnetic resonance imaging (fMRI) investigations have specifically highlighted the involvement of the amygdala, temporal plane, superior temporal sulcus and intraparietal sulcus in the auditory looming circuit as well prefrontal cortex (PFC), primary auditory cortex (PAC) and IPL in the preferential processing of looming sounds ( Bach et al, 2008 ; Seifritz et al, 2002 ).…”

Our auditory system constantly keeps track of our environment, informing us about our surroundings and warning us of potential threats. The auditory looming bias is an early perceptual phenomenon, reflecting higher alertness of listeners to approaching auditory objects, rather than to receding ones. Experimentally, this sensation has been elicited by using both intensity-varying stimuli, as well as spectrally varying stimuli with constant intensity. Following the intensity-based approach, recent research delving into the cortical mechanisms underlying the looming bias argues for top-down signaling from the prefrontal cortex to the auditory cortex in order to prioritize approaching over receding sonic motion. We here test the generalizability of that finding to spectrally induced looms by re-analyzing previously published data. Our 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. At time points following the motion onset, our findings show a bottom-up bias along the dorsal auditory pathway directed toward the prefrontal cortex.

In this article, we present the current state of the art in binaural audio with the focus on head-related transfer functions (HRTFs) and valuation methods of virtual acoustics with descriptive attributes. This combination provides a methodology, which delivers the basis for research studies in virtual reality (VR) on individual and non-individual head-related transfer functions. Based on the largely explored localization perception of static audio signals, this review offers an overview of the directional hearing during head and sound source movement and multimodality in audiovisual virtual environments. Perceptual quality characteristics provide evaluation methods from which future HRTF VR experiments and virtual environments studies on binaural acoustics could benefit.

“…AN firing patterns propagate to higher stages along the auditory pathway, first through the auditory brainstem, then towards more cortical regions [ 62 ]. On its way, AN spiking is mapped onto fluctuation patterns by neurons that are sensitive to the amplitude of low-frequency fluctuations [ 63 ].…”

“…Our analyses focus on model approximations of the modulation processing circuits of the ventral cochlear nucleus (CN) and inferior colliculus (IC) [ 43 ], as well as on different modulation-filter-bank variants [ 27 , 31 ]. As a result, we exclude the analysis of other subcortical structures such as those that play a particular role in the binaural interaction between ears (e.g., the dorsal cochlear nucleus and superior olive) [ 62 , 64 ].…”

A number of auditory models have been developed using diverging approaches, either physiological or perceptual, but they share comparable stages of signal processing, as they are inspired by the same constitutive parts of the auditory system. We compare eight monaural models that are openly accessible in the Auditory Modelling Toolbox. We discuss the considerations required to make the model outputs comparable to each other, as well as the results for the following model processing stages or their equivalents: Outer and middle ear, cochlear filter bank, inner hair cell, auditory nerve synapse, cochlear nucleus, and inferior colliculus. The discussion includes a list of recommendations for future applications of auditory models.
