A questionnaire on (1) difficulties in everyday sound localization (localization disabilities), (2) limitations and disadvantages related to such disabilities (localization handicaps), and (3) everyday speech hearing disabilities was completed by 104 people with symmetrical hearing losses. Respondents considered situations when listening with and without their usual hearing aid fittings. The he...

The present thesis investigated cognitive ability in children with severe to profound hearing impairment who have received cochlear implants (CIs). The auditory stimulation from a cochlear implant early in life influences most cognitive functions as a consequence of the plasticity of the brain in the young child. It is important to understand the cognitive consequences of auditory stimulation f...

OBJECTIVES Previous research has attributed older adults' difficulty with perceiving speech in noise to peripheral hearing loss. However, recent studies have suggested a more complex picture and implicate the central nervous system in sensation and sensory deficits. This study examines the relationship between the neuroanatomical structure of cognitive brain regions and the ability to perceive ...

background and aim: cued speech makes speech perception easier and improves both lip-reading ability and residual hearing usage. the purpose of the present study was to assess the effectiveness of using cued speech on story retelling as a rehabilitation tool for late cochlear implanted, prelingual, hearing-impaired students. methods: this was an experimental study with a pre- and post-test plan...

This paper summarizes findings from a population study on outcomes of children with hearing loss in Australia, the Longitudinal Outcomes of Children with Hearing Impairment ( http://www.outcomes.nal.gov.au ) study. Children were evaluated at several intervals using standardized tests, and the relationship between a range of predictors and the outcomes was examined. This paper reports the perfor...

The present study examined the performance of 40 normal-hearing young adults and 38 elderly adults, some normal hearing and some hearing impaired, on the Department of Veterans Affairs' new compact disc (VA-CD) for auditory perceptual assessment. Principal-components factor analyses were performed on the test scores from each group of subjects with very similar results obtained from each group ...

An auditory hallucination shares with imaginal hearing the property of being self-generated and with real hearing the experience of the stimulus being an external one. To investigate where in the brain an auditory event is "tagged" as originating from the external world, we used positron emission tomography to identify neural sites activated by both real hearing and hallucinations but not by im...

In a retrospective case study of a patient with a right-sided cerebellopontine angle mass lesion, transient evoked otoacoustic emissions were robustly present despite a severe to profound sensorineural hearing loss and abnormal auditory brainstem response. These results were interpreted as suggestive of a neural site of lesion, and the potential for planned, preserved, or improved hearing by a ...

The speech-perception ability reported from profound hearing impaired persons using different technical aids: hearing aids, cochlear implants, or tactile aids, varies widely. A test-battery was constructed that consisted of segmental and suprasegmental tasks and speech tracking. Two presentation modalities were used, vision only and visual information supplemented with the assistive device. Dea...

Background: Hearing is the ability to perceive sound. A person said have hearing loss when he/she not able hear as well someone with a normal threshold of 25 dB or better in both ears. Binocular function plays an important role it helps coordinate eyes.Methodology: prospective study was conducted 103 subjects. After taking permission authority and impairment school, consent taken from participa...
