Filter by:The aim of this clinical investigation is to collect data on objective and subjective hearing performance, quality of life and safety in adult subjects with conductive hearing loss, mixed hearing loss or single-sided sensorineural deafness.
clEAR's auditory brain training has been shown to be effective in improving childrens' abilities to recognize the speech of generic talkers in a laboratory setting. In the proposed research, the researchers will build upon these results and assess the extent to which auditory brain training delivered via the web enhances children's abilities to recognize the speech of a potential classroom teacher and diminishes their communication challenges that are associated with significant hearing loss. First, investigators will conduct focus groups with children who have undergone training with the research version of clEAR's pediatric games, then they will recode the games from LabView to Java Script, making changes in the games in response to the focus group comments, and finally, they will collect data from 20 children to assess whether web-based auditory brain training improves their abilities to recognize the speech of their (hypothetical) upcoming school year's classroom teacher.
An open-set sentence speech recognition in noise test in Cantonese Chinese, which is applicable on children and adults with hearing impairment, is proposed to be developed in this project.
A methodical evaluation of novel sound changing principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These sound changing principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and asses strength and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Both, objective laboratory measurements as well as subjective evaluations in real life environment will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa
Neonatal hearing screening may fail due to some perinatal and neonatal factors. It is well known that false positivity in newborn hearing screening increases cost and maternal anxiety and anxiety. There is still widespread concern about the use of opoid analgesics to relieve pain during labor. The aim of this study was to determine the effects of pethidine administered during labor on neonatal hearing screening test false positivity rates.
The aim of this study is to investigate the effect of varying additional factors on loudness summation in Neuro Zti Cochlear Implant users.
The purpose of this study is to evaluate the benefit of bilateral implantation with bone-anchored hearing systems (BAHS), in terms of sound localization abilities, as well as auditory working memory. The hypothesis is that the use of two BAHS (bilateral condition) will not only improve localization abilities, but it will also increase the ability to retain words in working memory, compared to performance with only one BAHS (unilateral condition).
Main objective: Show the superiority of Fine Structure (FS4) strategy compared to Continuous Interleaved Sampling (HDCIS) strategy on the qualitative preference for the listening of musical pieces. Secondary objectives - Show the superiority of FS4 strategy compared to the HDCIS strategy on the perception of musical elements (contour test). - Analyze the link between the results of musical perception tests and the subjective preference of musical listening. - Show the non inferiority of FS4 strategy compared to the HDCIS strategy on the perception of speech elements. - Analyze the link between the results of musical perception tests and the results of the perception of speech elements. - Analyze the qualitative multidimensional perception with HDCIS and FS4
Phonak Hearing Systems pass through different development and study stages. At an early stage, feasibility studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interdependency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, as a result, they get optimized. Afterwards, and prior to product launch, the Phonak Hearing Systems undergo a final quality control in terms of clinical trials. This is a pre-validation study, investigating optimized algorithms, features, functions and wearing comfort. This will be a clinical evaluation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).
Participants will take part in both a passive and active emotion recognition task: (1) passively listening to semantically-neutral sentences with emotional prosody, and (2) actively listening and subsequently categorizing emotional sentences and sounds. Participants are seated and instructed to stare at a fixation cross while the stimulus is played. During this study, non-invasive physiological measurements of pupil dilation will be recorded from the participants. Using this paradigm we will be assessing the effect of frequency lowering on emotion recognition. The study takes the form of a partly three factorial design (passive task x frequency lowering x acclimatization). Participants also perform a two factor design (active task x frequency lowering). Each participant performs two passive tests (20 minutes long each) with frequency lowering on and off, and a four week acclimatization period in-between. Participants perform one active listening task after the acclimatization period with frequency lowering on and off.
