Introduction Human hearing is concerned with the perception and interpretation of sensory input to the ears. Such perception may be classiied as auditory events as opposed to sound events 5-1]. A sound event is the physical phenomenon of mechanical vibration which can characterize a sound source, while an auditory event is the brain's perception of an auditory phenomenon which may or may not be...

Purpose: To assess the auditory perceptual performance of children in a task of identification of vowel contrasts, to classify which phonemes and vowel contrasts provide higher or lower degrees of difficulty, and to verify the influence of age in this performance. Methods: Data recordings of auditory perceptual performance of 66 children in a task of identification using the software Perception...

Tinnitus is an aversive auditory percept of unknown origin. We tested the speculation that tinnitus may share neuronal processing mechanisms with aversive auditory percepts of known origin. This study revealed the functional neuroanatomy of the perception of aversive auditory stimuli. The stimuli were presented to 12 healthy volunteers so as to mimic the psychoacoustical features of tinnitus an...

Current theories of auditory pitch perception propose that cochlear place (spectral) and activity timing pattern (temporal) information are somehow combined within the brain to produce holistic pitch percepts, yet the neural mechanisms for integrating these two kinds of information remain obscure. To examine this process in more detail, stimuli made up of three pure tones whose components are i...

Auditory cortex is the first cortical region of the human brain to process sounds. However, it has recently been shown that its neurons also fire in the absence of direct sensory input, during memory maintenance and imagery. This has commonly been taken to reflect neural coding of the same acoustic information as during the perception of sound. However, the results of the current study suggest ...

A hallmark of the developing auditory cortex is the heightened plasticity in the critical period, during which acoustic inputs can indelibly alter cortical function. However, not all sounds in the natural acoustic environment are ethologically relevant. How does the auditory system resolve relevant sounds from the acoustic environment in such an early developmental stage when most associative l...

This study examines how native language (L1) experience affects auditory–visual (AV) perception of nonnative (L2) speech. Korean, Mandarin and English perceivers were presented with English CV syllables containing fricatives with three places of articulation: labiodentals nonexistent in Korean, interdentals nonexistent in Korean and Mandarin, and alveolars occurring in all three L1s. The stimul...
