The Cochlear implant is an Australian invention (first prototype 1978), leading to the formation of Cochlear Ltd. to commercialise it. Cochlear Ltd. has now delivered implants to over 60,000 people in 70 nations across the world. Copycat companies have arisen overseas, but Cochlear Ltd. remains the market leader, due to their commitment to ongoing R&D. The present project involves magnetic resonance imaging and finite element analysis to study the current leakage pathways in the cranial cavity for the purpose of optimizing the design and placement of the return electrode. The obvious benefit of this is longer battery life. Better understanding of current leakage over other intracranial nerves is the other anticipated benefit.Read moreRead less
Conformal Bionics - addressing the challenges in bringing miniaturised implants to the site of therapeutic delivery. Smaller, more sophisticated, lifetime-implantable bionic devices capable of being placed at the site of therapeutic delivery will facilitate new or improved opportunities for treatment of disease. Three critical areas of research aim to be explored in pursuit of this goal will be addressed within this study: introduction of new fabrication materials that enable devices to conform ....Conformal Bionics - addressing the challenges in bringing miniaturised implants to the site of therapeutic delivery. Smaller, more sophisticated, lifetime-implantable bionic devices capable of being placed at the site of therapeutic delivery will facilitate new or improved opportunities for treatment of disease. Three critical areas of research aim to be explored in pursuit of this goal will be addressed within this study: introduction of new fabrication materials that enable devices to conform to the anatomy of the targeted site of therapeutic delivery; improved means of addressing the data and energy transfer needs of devices implanted in confined spaces; and innovation of novel sensors for testing and monitoring of atmospheric conditions within the implant to anticipate and safely manage issues relating to a breach of hermetic encapsulation barriers.Read moreRead less
Bilateral Cochlear Implants for Children: Does a Second Implant Improve Language, Psychosocial and Other Outcomes? Severe-profound congenital hearing loss engenders significant costs to society. In 2005, specialised education cost -- on average $25,000 per child, loss of productivity cost -- $6.7 billion, and social security benefits were paid to approximately 129,000 individuals who were unemployed due to hearing loss. If bilateral cochlear implantation results in improved language, social dev ....Bilateral Cochlear Implants for Children: Does a Second Implant Improve Language, Psychosocial and Other Outcomes? Severe-profound congenital hearing loss engenders significant costs to society. In 2005, specialised education cost -- on average $25,000 per child, loss of productivity cost -- $6.7 billion, and social security benefits were paid to approximately 129,000 individuals who were unemployed due to hearing loss. If bilateral cochlear implantation results in improved language, social development, and academic outcomes, the community benefits arising will be greatly improved quality of life for these individuals and significant savings to society. In partnership with Cochlear Ltd, this study will provide some of the first data worldwide comparing the effects of an additional implant on language, social and educational outcomes.Read moreRead less
The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of co ....The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of cognitive decline, whether hearing loss is causal, and whether the process can be altered. These findings should be applicable to all individuals with hearing loss. If cochlear implants delay cognitive decline, this would significantly affect policy, quality of life for the elderly, and the cost to society.Read moreRead less
Auditory and Vestibular Ringing--Detection and theraputic interventions. Tinnitus effects up to 30% of the elderly population. To date no single suppression modality has been successful across all tinnitus sufferers. This study will apply an aural, low level, modulated, fractal suppression strategy designed to induce a "natural" olivary efferent response capable of suppressing/reducing tinnitus.

Balance disorders e.g. Meniere's Disease and nausea (seasickness) are unwanted outcomes of vestibular dysfunction/hypersensitivity. This study will apply a low level, low frequency, modulated, acoustic pressure wave designed to induce a ?natural? olivary efferent response and an end organ endolymph/perilymph balance shift. It is postulated these stimuli will reduce the effects of vestibular dysfunction/hypersensitivity.

A longitudinal study of language learning to assess early intervention outcomes in pre-school children with impaired hearing. Overseas research suggests that young children with impaired hearing and normal non-verbal cognition can develop normal language if hearing aid fitting and intervention occur before 6 months of age. Australian studies show considerable language delays in most hearing-impaired children of primary-school age. We will study the spoken language learning of hearing-impaired ....A longitudinal study of language learning to assess early intervention outcomes in pre-school children with impaired hearing. Overseas research suggests that young children with impaired hearing and normal non-verbal cognition can develop normal language if hearing aid fitting and intervention occur before 6 months of age. Australian studies show considerable language delays in most hearing-impaired children of primary-school age. We will study the spoken language learning of hearing-impaired children up to age 6 years in Victoria. The project will investigate crucial factors in achieving normal language learning in hard-of-hearing children and the role of early intervention. Normal language outcomes would enhance the educational and career prospects of hearing-impaired children and result in community cost savings.

Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
Detecting language disorder in children with a language background other than English: the role of the Dynamic Assessment. 17.6% of Australia's culturally diverse population are born in non-English speaking countries. Recently, reports of unprecedented growth in the diagnosis of children with language disorders have emerged. There are difficulties in accurately identifying children at risk of language disorder.

Recently, reports of unprecedented growth in the diagnosis of children with language disorders have emerged. There are difficulties in accurately identifying children at risk of language disorder. We hypothesize that some children with language backgrounds other than English (LBOTE) are mis-identified. If true, then scarce resources are being misdirected and inappropriately allocated, depriving children with true language disorder of support and intervention. The aim of this project is to determine the utility of the Dynamic Assessment to discriminate normal language learning from language learning difficulties in LBOTE children.
