Three experiments examine attentional differences in auditory localization using either endogenous or exogenous visual cues. Participants were presented with visual cues on a computer screen and asked to localize auditory targets presented through headphones. In conditions in which the auditory and visual stimuli traveled in the same direction, participants showed illusory directional hearing (Hari in Neurosci Lett 189:29-30, 1995) in that the targets were perceived to travel through the head. In conditions in which the directions of the auditory and visual stimuli were conflicting, participants localized the auditory targets as traveling in the direction of the visual cues. These data suggest that visual capture plays a predominate role in the processes of auditory localization that occurs within the head. Additionally, endogenous response times were significantly greater than exogenous response times. We propose this is the result of additional time required to shift one's attentional window in the endogenous condition.

Each perceptual process is accompanied with an evaluation regarding the reliability of what we are perceiving. The close connection between confidence in perceptual judgments and planning of actions has been documented in studies investigating visual perception. Here, we extend this investigation to auditory perception by focusing on spatial hearing, in which the interpretation of auditory cues can often present uncertainties.

As artificial intelligence advances and demand for cost-effective equipment maintenance in various fields increases, it is worth insightful research on utilizing robots embedded with sound source localization (SSL) technology for condition monitoring. Combining the two techniques has significant advantages, which are conducive to further classifying and tracking abnormal sources, thereby enhancing system performance at a lower cost. The paper provides an overview of current acoustic-based robotic techniques for condition monitoring, highlights the common SSL methods, and finds that localization performance heavily depends on signal quality.

Harmonicity is an organizing principle in the auditory system, facilitating auditory object formation. The goal of the current study is to determine if harmonicity also facilitates binaural fusion. Participants listened to pairs of two-tone harmonic complex tones that were harmonically or inharmonically related to each other.

Thanks to affordable 3D printers, creating complex designs like anatomically accurate dummy heads is now accessible. This study introduces dummy heads with 3D-printed skulls and silicone skins to explore crosstalk cancellation in bone conduction (BC). Crosstalk occurs when BC sounds from a transducer on one side of the head reach the cochlea on the opposite side.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.
