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)
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)
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)
This paper examines whether observed phenomena in energy declination can be used to improve the naturalness of synthetic speech. In two production experiments different aspects of intensity fall-off within utterances are analysed including degree of stress, phrase length, phrase boundaries. Energy manipulation was carried out using diphone synthesis as a(More)
In a clinical experiment, it was found that there is a high correlation between the compliance measured by tympanometry and the minimum size of the earmold vent, which just solves the client's occlusion problem related to his/her own voice when using a hearing aid. For ears with sensorineural hearing losses, compliance explained 59 percent of the variation(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)
— We present a robust method for 3D rigid registration of 2D open manifolds based on distance maps using an initial-ization step, a Gibbs sampler for optimization supplemented by an Iterated Conditional Modes (ICM) optimizer. The algorithm is fully automatic based on very simple information of the initial orientation of the given objects.
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)
Emergency software problems may present an immediate danger to public health, safety, general welfare or business. Hence, the organisations must be well prepared to handle them with the greatest expediency. Unfortunately, the software community has paid little attention to the emergency corrective maintenance. Today, we do not have any standard process(More)
