Auditory nerve single-unit studies have demonstrated that phase-locking plays an important role in the neural encoding of the spectrum of speech-like sounds. Recently, it has been reported that the phase-locked activity underlying the scalp-recorded human frequency-following response (FFR) also encodes the first two formants of several steady-state vowels and the time-variant frequency presente...

objectives: language development is often very slower in hearing impaired children compared with their normal peers. hearing impairment during childhood affects all aspects of speech production and language acquisition. it seems that hearing impaired people suffer from language and speech impairments such as production of complex linguistic structures. the purpose of this study is to determine ...

The objective of the study is to provide some implications for rehabilitation of hearing impairment by investigating changes of neural activities of directional brain networks in patients with long-term bilateral hearing loss. Firstly, we implemented neuropsychological tests of 21 subjects (11 patients with long-term bilateral hearing loss, and 10 subjects with normal hearing), and these tests ...

Human listeners prefer consonant over dissonant musical intervals and the perceived contrast between these classes is reduced with cochlear hearing loss. Population-level activity of normal and impaired model auditory-nerve (AN) fibers was examined to determine (1) if peripheral auditory neurons exhibit correlates of consonance and dissonance and (2) if the reduced perceptual difference between...

consanguineous marriage is strongly favored in many large human populations. in the most parts of south asia, consanguineous marriage account for 20%  to over 50% of the general population. the effect of consanguinity on hereditary deafness has been well studied and documented. many authors have suggested that approximately one half  of sensory neural hearing loss in children can be attributed ...

1. Most individuals with chronic tinnitus have highfrequency hearing loss, induced by noise exposure, otological disease, or the aging process. Physiological evidence suggests that in such individuals, tinnitus is likely caused not by irritative processes that persist in the ear after cochlear injury, but by changes that occur in central auditory pathways when the ear is partly disconnected fro...

OBJECTIVE To compare the health-related quality of life (HRQOL) of primary school-age deaf children with or without motor impairment to that of typically developing peers. METHODS This study was a prospective, cross sectional study. With age-matched controls, 100 children were analyzed in each of the following three categories: normal hearing, hearing impaired without motor impairment, and he...
