Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

OBJECTIVES To detect a mitochondrial mutation responsible for maternally transmitted hearing loss with late-onset neurologic features in a 3-generation Dutch family, and to describe the hearing loss, associated symptoms, and vestibular dysfunction. PATIENTS AND METHODS All maternally related family members (n = 69) were investigated using standard audiometry. In a selected group, vestibulo-oc...

OBJECTIVE Hearing impairment in children across the world constitutes a particularly serious obstacle to their optimal development and education, including language acquisition. Around 0.5-6 in every 1000 neonates and infants have congenital or early childhood onset sensorineural deafness or severe-to-profound hearing impairment, with significant consequences. Therefore, early detection is a vi...

This brief paper describes the background to the literacy activities designed in our project and then considers its fit with the National Curriculum. The main assumption behind the idea of setting up the family-school partnership is that hearing and deaf children must reach similar aims in literacy; so it is possible to start the children‟s learning in the classroom with the same activities. Ho...

The Internet has become an ordinary and widely accepted alternative social environment—known as cyberspace—in which many people take part in numerous activities. For the hearing-impaired, cyberspace provides extra benefits for two basic reasons: means of communication, which is primarily based on visual (text and images) and not auditory channels, and the convenient possibility of concealing th...

OBJECTIVE To evaluate the improvement in speech intelligibility in noise obtained with an assistive real-time fixed endfire array of bidirectional microphones in comparison with an omnidirectional hearing aid microphone in a realistic environment. DESIGN The microphone array was evaluated physically in anechoic and reverberant conditions. Perceptual tests of speech intelligibility in noise we...

background and aims: this is a pilot study investigated the prevalence of hearing impairment and the impact of the known risk factors for hearing loss on infants at risk born in kuwait. methods: two hundred infants with risk of hearing impairment who met the joint committee on infants hearing (1990) criteria were screened. all newborns were included in this study if they had hospital stay for m...

BACKGROUND Speech perception ability depends on auditory and extra-auditory elements. The signal- to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...
