Filter by:Nowadays in France, there is no organized screening of the hearing loss in the elderly; however, it is a very common disease and simples tests to perform to detect it exist. Lots of studies use surveys to identify deaf people; but physicians often consider them too sensitive and less specific because lots of people were classified into " deaf " people meanwhile they have a subnormal tonal audiogram. Now, it's known that it corresponds to the "Hidden Hearing Loss" concept: it's defined as an auditive disturbance in a noisy ambiance in people with a normal tonal audiometry; corresponding to infraclinical cochlear lesions. These lesions, if detected early, can be prevented to avoid an audition degradation in time. The aim of the study is to determinate the values of sensitivity and specificity of the HHIE-S survey translated into French, so it could be used as a screening method of hearing loss in the elderly and as a prevention of cochlear damages.
The investigators are interested in an additional hearing aid feature called non-linear frequency compression (NLFC). This aims to improve audibility of high frequency sounds by converting them into lower frequencies and has been shown to benefit those with moderate-severe sensorineural hearing loss (SNHL). Cochlear dead regions (DRs) are areas of the inner hearing organ (the cochlea) where there is little or no function and are commonly found in regions responsible for detecting high pitched (frequency) sounds. Not all people with hearing loss have DRs. The investigators would like to determine whether based on the presence or absence of DRs, patients with moderate-severe SNHL perform better or prefer their hearing aids programmed conventionally, or with NLFC activated. To do this, two participant groups will be created based on findings from the threshold equalising noise (TEN) test which identifies cochlear DRs. Two participant groups will be created; one group with DRs and one group without DRs. All participants will receive two hearing aids and will wear these programmed conventionally for ~six weeks and with NLFC activated for ~six weeks in a counterbalanced manner. Following each condition, participants will complete a questionnaire and various speech tests will be performed. This involves participants repeating sentences, words or speech sounds they hear from a speaker in quiet and in the presence of background noise. Individuals' scores will be calculated for each test and their performance when NLFC was activated and deactivated will be compared. This will be analysed alongside the questionnaire data to compare the 'DR' and 'no DR' group in both conditions. Findings may help to determine whether NLFC should be activated for all moderate-severe SNHL patients, or just those with DRs, helping clinicians to optimise hearing aid settings for patients.
The purpose of this study is to evaluate the safety, tolerability, and exploratory efficacy of OTO-413 administered as an intratympanic injection for the treatment of speech-in-noise hearing impairment.
This is a phase 2a single and repeat dose exploratory efficacy study of intratympanic FX-322 compared to placebo in healthy male and female adults with stable sensorineural hearing loss.
Deafness significantly affects several auditory tasks of everyday life in children: understanding speech in quiet and noisy environments, spatial location of sounds ... These difficulties in locating sound sources are often ignored by parents and underestimated by children. Nowadays we there is specific tools to evaluate these problems in children. Indeed, there is a validated French questionnaire (Speech and Spatial Questionnaire SSQ) for adults that evaluates auditory abilities, including sound localization, in different tasks of daily life. Although robust, this questionnaire includes 49 questions and is too long for daily use in consultation. For this reason, Moulin et al validated in 2018 a short version of the SSQ questionnaire for adults with only 15 items. Based on this model, the aim of this study is to develop and test a paediatric questionnaire with 12 items to assess more specifically auditory difficulties in deaf children. This questionnaire will follow the validated frame of the adult SSQ questionnaire and will consist of three subscales: speech hearing (4 items), spatial hearing (4 items), and qualities of hearing (4 items). These 3 subscales are identical to those defined in long and short form pf the adult SSQ questionnaire.
Technological advances in hearing aids and telecommunications, including the widespread availability of telehealth (referred to in this proposal as "e-Audiology") applications, have the potential to expand both access and affordability of hearing aids for those with age-related hearing loss (ARHL). E-Audiology is used by clinicians in a variety of settings, including private practice, university clinics, and the Veterans Administration. The American Speech-Language-Hearing Association recently updated the Scope of Practice guidelines for audiology to include telehealth as "an alternative method of service delivery that en-compasses both diagnostics and intervention services.", including all aspects of hearing aid selection, fitting, and follow-up counseling and rehabilitation. However, given the paucity of evidence of comparative efficacy between office-based service delivery and e-Audiology in real-world settings, patients and relevant stakeholders are faced with a major decisional dilemma when determining which mode of service delivery would be optimal for addressing the needs, preferences, and lifestyles of those with ARHL. Thus, the purpose of this study is to determine the benefits, drawbacks, and patient satisfaction associated with e-Audiology delivery of hearing aid fitting, services, and supports for older adults with mild to moderate ARHL. We plan to use data collected in this pilot study for a future R01 submission to the NIH.
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.
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).
