Filter by:The aim of this study is to establish the connection between the cochlear implant programming parameters with the auditory effort associated with the speech perception evaluated by pupillometry techniques in different audiometric conditions.
Overhearing is important for vocabulary learning and speech and language development in young children. However, contemporary hearing aids are generally unable to provide adequate access to low-level auditory inputs from multiple talkers at a distance to capitalize on overhearing. A recent investigation by Jace Wolfe and colleagues showed that, even when aided, children with hearing loss had significantly poorer speech recognition at 40, 50 and 60 dBA compared to children with normal hearing. Furthermore, they showed that increasing hearing aid gain for very low-level inputs produced a statistically significant improvement in syllable-final plural recognition and a non-significant trend toward better monosyllabic word recognition at very low presentation levels. Additional research is needed to document low-level speech recognition ability of children with hearing loss as well as the potential benefit or detriment of increasing hearing aid gain for low-level inputs. A novel hearing aid technology known as Soft Speech Enhancer has been shown improve low-level speech perception in adults with hearing loss; however, the effect of Speech Enhancer on speech recognition in children is not yet known and will be evaluated.
This clinical study aims to investigate speech performance in quiet with an OTE Sound Processor with modified firmware compared with the commercially available CP1150. The study also investigates CP1110 and CP1150 with Forward Focus.
The purpose of the study is to evaluate the efficacy of a prototype app for the self-fitting of hearing aids.
The purpose of this study is to evaluate the safety and effectiveness of cochlear implantation in adults 65 years of age and older.
This is a study of the feasibility of activating the auditory system by an electrode in direct contact with the cochlear nerve.
The purpose of this study is to evaluate if the effects of in-person speech-language therapy with a novel digital storybook intervention platform (Hear Me Read) improves vocabulary, speech and language, and literacy outcomes in young children who are deaf or hard of hearing compared with in-person therapy alone.
In 2008, the Handicap-Santé survey counted 10 million people with hearing difficulties in France, i.e. 16% of the national population. For 5.4 million of these people, the hearing limitations considered to be moderate to total, are likely to have repercussions on their daily life. In 2010, 600,000 people with hearing loss wore hearing aids, including 360,000 with very severe to total limitations who were unable to follow a conversation with others. Hearing loss can impact hearing skills (comprehension in noisy environments or with multiple speakers) and be a source of cognitive decline. It can also limit the quality of exchanges, communication and information taking. Several studies have shown that hearing loss can also have a negative effect on quality of life, psychological well-being, personal fulfillment, social relationships and can lead to social isolation, depression and/or anxiety. Currently, the treatment of people with hearing loss is often limited to hearing aids from a hearing aid specialist. Hearing rehabilitation and lip-reading training with a speech therapist may be offered at a later stage. However, many people who have been fitted with a hearing aid describe a decrease in their quality of life despite the fitting. Current treatment seems to deal mainly with auditory-cognitive problems. To date, no multidisciplinary rehabilitation services seem to be offered in France to take into account the other consequences of this condition: anxiety, depression, and limitations in social participation.
The purpose of this study is to understand performance with a cochlear implant. The long-term goals of this research are to improve sound perception with cochlear implants and to better understand the functioning of the auditory system. Information from individuals with and without cochlear implants will be compared.
Project synopsis: This prospective cohort study investigates impact of (1) hearing loss and (2) cochlear implantation on cost and health state on one hand, and employment, productivity and social wellbeing on the other hand in a professionally active group using validated questionnaires. Participants: The investigators aim to include 100 professional active adults between 18 and 65 years old. All participants have a bilateral severe-to-profound sensorineural or mixed hearing loss. Due to several reasons such as an optimal hearing aid fitting, the presence of a residual hearing or physical contra-indications, half of these participants will not be implanted with CI. Additionally, 100 participants with a single-sides deafness (SSD) in the acute or chronic setting (SDD present for at least three months) will be included. Study design Study measures: All audiological tests and patient-reported outcome measures will be included in this test protocol and repeated throughout the follow-up visits depending on aided or unaided setting. The cognitive evaluation will be executed during the first and last test moment. The investigators anticipate that the protocol will take 1 hour per follow-up in the hospital (audiological testing and to go over the questionnaires), plus an extra hour at home to fill out the questionnaires. For the cognitive tests, an extra hour in the hospital will be scheduled. Hypothesis As a primary endpoint, the investigators anticipate demonstrating that severe-to-profound hearing loss has a significant impact on sick leave and self-reported productivity. Health state will also be analyzed as a secondary endpoint because the investigators anticipate only marginal improvement (if any) on these instruments due to the lack of sensitivity and responsiveness, even in this population. The investigators will also determine the rate of usage and non-usage at this long-term follow-up to demonstrate the utility of cochlear implants. Statistical analysis IBM SPSS Statistics (IBM; Armonk, NY) will be used for the statistical analyses. The participants' hearing profiles will be summarized using descriptive statistics (median, and range). In view of the sample size, non-parametric tests and linear mixed models (to describe evolution in time and difference between groups) will be used. Quantitative data will be presented as median and range (minimum and maximum). Descriptives will be used to summarize the outcomes of the subjective data logging. For the speech perception in noise results, a Wilcoxon signed-rank test will be used. In addition, to correct for the multiple speech in noise test configurations, Holm's correction will be applied. The level of significance will be set at p.0.05.
