abstract background: previous studies have indicated an unspecific correlation between noise exposure and blood pressure disturbances. blood pressure disturbances could be caused by the environmental hazards such as noise exposure. the aim of this study is to analyze whether there is a relationship between noise exposure and hypertension. methods: atotal sample of 218 workers working in a small...

The classic view of sensorineural hearing loss has been that the primary damage targets are hair cells and that auditory nerve loss is typically secondary to hair cell degeneration. Recent work has challenged that view. In noise-induced hearing loss, exposures causing only reversible threshold shifts (and no hair cell loss) nevertheless cause permanent loss of >50% of the synaptic connections b...

In this research, we developed a robust two-layer classifier that can accurately classify normal hearing (NH) from hearing impaired (HI) infants with congenital sensori-neural hearing loss (SNHL) based on their Magnetic Resonance (MR) images. Unlike traditional methods that examine the intensity of each single voxel, we extracted high-level features to characterize the structural MR images (sMR...

The mammalian cochlea is a highly complex structure which contains several cells, including sensory receptor or hair cells. The main function of the cochlear hair cells is to convert the mechanical vibrations of the sound into electrical signals, then these signals travel to the brain along the auditory nerve. Auditory hair cells in some amphibians, reptiles, fish, and birds can regenerate or r...

Hearing loss has been the most prevalent sensory disability throughout the world. In Malaysia, National and Hearing Disorder Survey has reported that the prevalence of hearing disorder is about 17.14% with an estimated population of 28.8 million and 1.5% newborns have the onset of hearing impairment. A conventional hearing screening test’s applicability is limited as it requires a feedback resp...

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 ...

  Background : Normal hearing is essential for development of appropriate academic and psychosocial skills in children. Many causes of hearing loss are preventable and curable. The aim of this study was to investigate the prevalence of types and probable causes of hearing loss in 15-5 years old hearing impaired children in Isfahan.   Methods: In a cross-sectional descriptive study conducted dur...
