BACKGROUND Recently, a model of the ossicular chain for finite element analysis has been developed. However, the natural vibration characteristics of human ossicles have never been studied. Herein, we investigated the dynamic characteristics of the coupling of in-vivo ossicles using finite element analysis. METHODS The geometry of the ossicular chain was obtained by high-resolution computed t...

Perceived synchrony of visual and auditory signals can be altered by exposure to a stream of temporally offset stimulus pairs. Previous literature suggests that adapting to audiovisual temporal offsets is an important recalibration to correctly combine audiovisual stimuli into a single percept across a range of source distances. Healthy aging results in synchrony perception over a wider range o...

In an attempt to delineate the assumed 'what' and 'where' processing streams, we studied the processing of spatial sound in the human cortex by using magnetoencephalography in the passive and active recording conditions and two kinds of spatial stimuli: individually constructed, highly realistic spatial (3D) stimuli and stimuli containing interaural time difference (ITD) cues only. The auditory...

We studied the cortical processing of spatial stimuli by magnetoencephalographic (MEG) measurements using broadband noise bursts presented from eight sound source directions in the horizontal plane. The stimuli were individually created for each subject by using three-dimensional (3D) sound techniques. The subjects carried out a behavioral task where their accuracy for localizing the 3D stimuli...

Cochlear hair cells convert sound vibration into electrical potential, and loss of these cells diminishes auditory function. In response to mechanical stimuli, piezoelectric materials generate electricity, suggesting that they could be used in place of hair cells to create an artificial cochlear epithelium. Here, we report that a piezoelectric membrane generated electrical potentials in respons...

Radio’s capacity to stimulate the creation of mental images in the mind of its listeners has long been acknowledged. Nevertheless, research into mental imagery has focused principally on the study of visual stimuli, although studies into radio itself have mostly concerned the field of advertising. In this study, we examine the influence of two stimuli associated with auditory processing on radi...

Abstract Background The vestibular system can perceive sound at high intensity levels. recording of evoked myogenic potentials (VEMPs) is one the clinical techniques that capture when activated by sound. In healthy individuals, it has been demonstrated VEMP thresholds are lower using low-frequency stimuli, particularly 500 Hz tone burst. Aging affects frequency tuning, causing shift to higher f...

The paper introduces a novel auditory BCI/BMI paradigm based on combined sound timbre and horizontal plane spatial locations as informative cues. The presented concept is based on responses to eight-directional audio stimuli with various tonal and environmental sound stimuli. The approach is based on a monitoring of brain electrical activity by means of the electroencephalogram (EEG). The previ...

Influence of whole-body vibration on reaction times was studied on a specially developed rig, with the subjects being exposed to no vibration, and vibration frequencies of 1, 5, 20 and 50 Hz. The shortest reaction times for both, sound and visual stimuli were measured for no vibration of the seating platform. The most detrimental influence was observed at vibration frequency of 5 Hz, with react...

Prior evidence has shown that a person's affective context influences attention to emotional stimuli. The present study investigated whether a crossmodal affective context that is induced by remembering an emotional sound modulates attention to visual emotional stimuli. One group of participants had to remember a positive, negative, or neutral sound during each trial of a dot probe paradigm. A ...
