OBJECTIVES This descriptive summary of the literature provides an overview of the available studies (published between January 1980 and January 2009) on correlates of help-seeking behavior for hearing loss, hearing-aid uptake, hearing-aid use, and satisfaction with the device. METHODS Publications were identified by structured searches in Pubmed and(More)
OBJECTIVE Qualitative research methodologies are being used more frequently in audiology as it allows for a better understanding of the perspectives of people with hearing impairment. This article describes why and how international interdisciplinary qualitative research can be conducted. DESIGN This paper is based on a literature review and our recent(More)
Today the design of custom in-the-ear hearing aids is based on personal experience and skills and not on a systematic description of the variation of the shape of the ear canal. In this paper it is described how a dense surface point distribution model of the human ear canal is built based on a training set of laser scanned ear impressions and a sparse set(More)
OBJECTIVES This study explored the meaning and determinants of optimal hearing aid use from the perspectives of hearing aid clients and audiologists. An additional objective was to contrast the perspectives of the clients and audiologists. DESIGN Four focus groups were conducted: (1) clients (n = 7) in Denmark, (2) clients (n = 10) in the United Kingdom,(More)
Based on observations of feeding structures and currents in the polychaete Spirorbis tridentatus, the entoproct Loxosoma pectinaricola and the cycliophore Symbion pandora, which all possess compound cilia, it is hypothesized that their capture mechanism is based on the catch-up principle. According to this principle, the compound cilia constitute the pump(More)
BACKGROUND Evidence suggests that hearing-aid users have difficulties with own-voice level control, most likely because their auditory feedback is affected by hearing-aid amplification. PURPOSE The purpose of this study was to investigate how changes to auditory feedback affect the voice level of hearing-aid users. RESEARCH DESIGN A correlational study(More)
OBJECTIVE This study investigated the perspectives of adults with hearing impairment on hearing help-seeking and rehabilitation. DESIGN Individual semi-structured interviews were completed. STUDY SAMPLE In total, 34 adults with hearing impairment in four countries (Australia, Denmark, UK, and USA) participated. Participants had a range of experience(More)
BACKGROUND The uptake and use of hearing aids is low compared to the prevalence of hearing impairment. People who seek help and take part in a hearing aid rehabilitation process participate actively in this process in several ways. PURPOSE In order to gain more knowledge on the challenges of hearing help-seeking and hearing aid use, this qualitative study(More)
Pervasive healthcare technology is needed to meet the challenges of an aging population in the western world, as well as an expected major shortage of healthcare personnel in the near future. The OpenCare Project is an open source infrastructure framework, designed to be used by researchers and corporate developers for developing experimental assisted(More)
A large number of ambient assisted living technologies coexist without a common language between them. They have different user interfaces, communication infrastructures and maintenance plans, which limit the inclusion of efficiency-enhancing solutions in the home care sector. Also, deployment of applications and devices are overly complex, and cannot be(More)
