The findings indicate significant developmental impacts of poor binaural hearing in children.Ĭhildren with hearing loss are at risk for poor perception of auditory space because they have difficulties hearing where sounds are coming from around them ( Selz et al., 1996). The remaining components revealed clusters of self-reported hearing, balance and vestibular function, and speech perception deficits. Principal component analyses revealed deficits in a main cluster of visuospatial memory, oral language, mathematics, and reading measures (explaining 46.8% data variability). Verbal memory was not significantly different than normal ( p > .05). Visuospatial memory deficits occurred in both hearing loss groups ( p = .02) but more consistently across tests in children with unilateral hearing loss. Children with unilateral hearing loss had more asymmetric speech perception than children with bilateral CIs ( p .05). Analyses revealed that children in both hearing loss groups had significantly poorer skills (accounting for age) on most tests than their normal hearing peers. Eighty-eight children (43 male:45 female, aged 9.89 ± 3.40 years), grouped by unilateral hearing loss ( n = 20), bilateral CI ( n = 32), and typically developing ( n = 36), completed a battery of sensory, cognitive, and academic tests. Both groups are at risk for vestibular/balance deficits which could further contribute to memory and learning challenges. Their cognitive and academic deficits could be unique from children receiving bilateral cochlear implants (CIs) at young ages who have poor access to spectral cues and impaired binaural sensitivity. Children with unilateral hearing have normal hearing in one ear but no access to binaural cues. Poor binaural hearing in children was hypothesized to contribute to related cognitive and academic deficits. Also, CROS (contralateral routing of sound) hearing aids are available that use a microphone in the nonhearing ear to transmit the sound to the hearing hear.Ĭontact us to discuss your hearing situation and what kind of hearing care solution is right for you.All subjects Allied Health Cardiology & Cardiovascular Medicine Dentistry Emergency Medicine & Critical Care Endocrinology & Metabolism Environmental Science General Medicine Geriatrics Infectious Diseases Medico-legal Neurology Nursing Nutrition Obstetrics & Gynecology Oncology Orthopaedics & Sports Medicine Otolaryngology Palliative Medicine & Chronic Care Pediatrics Pharmacology & Toxicology Psychiatry & Psychology Public Health Pulmonary & Respiratory Medicine Radiology Research Methods & Evaluation Rheumatology Surgery Tropical Medicine Veterinary Medicine Cell Biology Clinical Biochemistry Environmental Science Life Sciences Neuroscience Pharmacology & Toxicology Biomedical Engineering Engineering & Computing Environmental Engineering Materials Science Anthropology & Archaeology Communication & Media Studies Criminology & Criminal Justice Cultural Studies Economics & Development Education Environmental Studies Ethnic Studies Family Studies Gender Studies Geography Gerontology & Aging Group Studies History Information Science Interpersonal Violence Language & Linguistics Law Management & Organization Studies Marketing & Hospitality Music Peace Studies & Conflict Resolution Philosophy Politics & International Relations Psychoanalysis Psychology & Counseling Public Administration Regional Studies Religion Research Methods & Evaluation Science & Society Studies Social Work & Social Policy Sociology Special Education Urban Studies & Planning BROWSE JOURNALS These include bone-conduction systems (also known as bone-anchored hearing aids, or BAHA devices) that can help transmit vibrations from the nonhearing ear to the functioning ear. In less common cases in which there is a total hearing loss in one ear (also known as profound unilateral hearing loss or single-sided deafness), there are medical therapies that may help to re-create some of the effects of binaural hearing. Lower volume means less potential for sound distortion and feedback, which leads to higher-quality reproduction of sound. Also, a person wearing two hearing aids generally needs less amplification than someone wearing only one. Similarly, using more of your brain to focus on the sound you want to hear is tremendously important in overcoming one of the primary complaints of individuals with hearing loss: hearing among background noise.
