Introduction Many previous studies in auditory neurophysiology have used simple tonal stimuli to understand how neurons encode sound. While these studies have shed light on many important neural characteristics, pure tones do not typically occur in our environment. Instead, we are often surrounded by multiple sound sources with complex harmonic and transient components such as speech, environme...

The purpose of this study was to (a) apply the musical sound quality assessment method, Cochlear Implant-MUltiple Stimulus with Hidden Reference and Anchor (CI-MUSHRA), to quantify musical sound quality deficits in CI (cochlear implant) users with respect to high-frequency loss, and (b) assess possible correlations between CI-MUSHRA performance and self-reported musical sound quality, as assess...

An apparatus for the measurement of reaction time to both visual and auditory stimuli with a provision to vary intensity of stimuli and with facility for lateralisation of sound to the right or left ear has been described.

Accurate sound localization is based on three acoustic cues (interaural time and intensity difference and spectral cues from directional filtering by the pinna). In natural listening conditions, every spatial position of a sound source provides a unique combination of these three cues in "natural alignment." Although neurons in the central nucleus (ICC) of the inferior colliculus (IC) are sensi...

Attentional influence on sound-localization behavior of barn owls was investigated in a cross-modal spatial cuing paradigm. After being cued to the most probable target side with a visual cuing stimulus, owls localized upcoming auditory target stimuli with a head turn toward the position of the sound source. In 80% of the trials, cuing stimuli pointed toward the side of the upcoming target stim...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

This study proposed an auditory stimulation protocol based on Shadowing Tasks to improve the sound-evoked potential in EEG and efficiency of brain–computer interface system. We use stories as enhance users’ motivation presented sound stimuli via headphones enable user concentrate better keywords stories. The presents target with oddball P300 paradigm. To decline mental workload, we shift usual ...

Surviving in the natural environment requires the rapid switching of attention among potentially relevant stimuli. We studied electrophysiologically the involuntary switching time in humans performing a task designed to study brain mechanisms of involuntary attention and distraction (C. Escera et al., 1998, J. Cogn. Neurosci., 10, 590-604). Ten subjects were instructed to discriminate visual st...

It is well known that the perception of the position of audio and video stimuli is not independent. In general, video dominates the position if the position offset between audio and video is small. Most previous work focused on natural listening conditions and position offsets between audio and video in the horizontal plane. There is little research concerning offsets in vertical direction and ...

BACKGROUND Hearing evaluation in children. AIM To verify the Minimum Response Levels (MRL) through the use of Visual Reinforcement Audiometry (VRA) in the sound field, in 50 normal hearing children and in 25 children with hearing loss, taking into account the following variables: side of sound presentation, gender, age and type of stimulus. METHOD VRA was performed using pure tone frequency...
