It has been well documented, and fairly well known, that concomitant with an increase in chronological age is a corresponding increase in sensory impairment. As most people realize, our hearing suffers as we get older; hence, the increased need for hearing aids. The first portion of the present paper is how the change…

The sweet spot can be interpreted as the region where acoustic sources create a spatial auditory illusion. We study the problem of maximizing this sweet spot when reproducing a desired sound wave using an array of loudspeakers. To achieve this, we introduce a theoretical framework for spatial sound perception that can…

How does the auditory system implement spatial selection without a dedicated cortical map for space? One hypothesis holds that auditory spatial attention draws on a supra-modal network including the parietal-occipital cortex; an alternative implicates subcortical structures (e.g., superior colliculus) with no direct…

In complex acoustic environments, sound localization involves the integration of numerous interrelated auditory and cognitive cues, making it challenging to understand their relationship to brain activity. Here, we use virtual acoustics to probe the brain’s response to auditory distance cues in a realistic environment.…

Auditory externalization, the perception of a sound source as located outside the head, is essential for spatial hearing and auditory scene analysis. However, its neural correlates remain poorly understood. This study investigated differences in brain activation elicited by externalized versus internalized sound…

With the rapid development of spatial audio technologies today, applications in AR, VR, and other scenarios have garnered extensive attention. Unlike traditional mono sound, spatial audio offers a more realistic and immersive auditory experience. Despite notable progress in the field, there remains a lack of…

Auditory localization is a fundamental ability that allows to perceive the spatial location of a sound source in the environment. The present work aims to provide a comprehensive overview of the mechanisms and acoustic cues used by the human perceptual system to achieve such accurate auditory localization. Acoustic…

Navigating unfamiliar environments without vision is a considerable challenge for blind individuals, as it requires constructing accurate cognitive maps. Binaural audio feedback, which delivers spatialized auditory cues, has been proposed as a means of enhancing spatial navigation by leveraging the auditory system's…

Spatial hearing, the brain's ability to use auditory cues to identify the origin of sounds, is crucial for everyday listening. While simplified paradigms have advanced the understanding of spatial hearing, their lack of ecological validity limits their applicability to real-life conditions. This study aims to address…

Humans localize sound in the horizontal plane using two primary binaural cues: interaural time difference (ITD) and interaural level difference (ILD). ITD refers to the difference between the times that sounds reach the two ears. By comparing the time of the sound signal's arrival at each ear, the human auditory system…

Background: Head-related transfer functions (HRTFs) contain time and level cues and may be utilized in automatic algorithms to identify locations of sound, a desirable feature for next-generation hearing devices. Due to substantial variability in individual head sizes and ear acoustics, individualized HRTFs are…

Spatial representation is a crucial skill for everyday interaction with the environment. Different factors seem to influence spatial perception, such as body movements and vision. However, it is still unknown if motor impairment affects the building of simple spatial perception. To investigate this point, we tested…

The auditory system computes the position of a sound along each of the three spatial axes, azimuth, elevation and distance, from very different acoustical cues. The extraction of sound azimuth from binaural cues (differences in arrival time and intensity between the ears) is well understood, as is the representation of…

'A. Farnè' 'F. Pavani'] In everyday life, sound localization entails more than just the extraction and processing of auditory cues. When determining sound position in three dimensions, the brain also considers the available visual information (e.g., visual cues to sound position) and resolves perceptual ambiguities…

Hearing is an active process and recent studies show that even the ear is affected by cognitive states or motor actions. One example are movements of the eardrum induced by saccadic eye movements - known as “eye movement-related eardrum oscillations” (EMREOs). While these are systematically shaped by the direction and…

individuals Authors: ['Sara Finocchietti' 'Davide Esposito' 'Monica Gori'] Early blind individuals can localize single sound sources better than sighted participants, even under monaural conditions. Yet, in binaural listening, they struggle with understanding the distances between three different sounds. The latter…

Higher-order ambisonic rendering is an increasingly common acoustic field reproduction technique that enables presentation of virtual sounds at nearly any location in 3D space, relatively unconstrained by the veridical locations of loudspeakers. We evaluated whether 3D sound reproduction through a 9^th^ order ambisonic…

Listener envelopment refers to the sensation of being surrounded by sound, either by multiple direct sound events or by a diffuse reverberant sound field. More recently, a specific attribute for the sensation of being covered by sound from elevated directions has been proposed by Sazdov et al. and was termed listener…

To enhance immersive experiences, binaural audio offers spatial awareness of sounding objects in AR, VR, and embodied AI applications. While existing audio spatialization methods can generally map any available monaural audio to binaural audio signals, they often lack the flexible and interactive control needed in…

'Andrew J. King'] An ability to integrate information provided by different sensory modalities is a fundamental feature of neurons in many brain areas. Because visual and auditory inputs often originate from the same external object, which may be located some distance away from the observer, the synthesis of these cues…
