Filter by:The purpose of this study is to evaluate the efficacy of OpenSound Navigator (OSN), a hearing aid speech-enhancement algorithm developed by Oticon, as treatment for pediatric hearing aid users. The study used a within-subjects design with pre- and post-comparisons involving fifteen pediatric (ages 6-12) patients with symmetrical sensorineural hearing losses ranging from the mild to moderately-severe degree. All participants were fit with bilateral Oticon OPN™ behind-the-ear hearing aids set with the OSN algorithm enabled. The investigators evaluated hearing aid benefit through word recognition in noise (behavioral testing) and everyday hearing/listening abilities (parental/legal guardian reported) within one week of the hearing aid fitting (pre-intervention) and two months post fitting (post-intervention).
The Bonebridge system using the BCI 601 is marketed since 2012. Previous prospective, multi-center, non-randomized studies on the BCI 601 Bonebridge performed in adult and paediatric populations have shown a significant improvement in terms of aided sound field (SF) thresholds, word recognition scores (WRS), speech reception thresholds (SRT) and subjective device satisfaction. Safety was established by stable residual hearing and low complication rates. The Bonebridge, implanted in over 600 clinics worldwide, is the world's first active transcutaneous bone conduction implant (BCI) system. This study now focuses on the further developed BCI 602 (marketed since 2019) that has the same indication criteria and performance characteristics. The aim of this post-market clinical follow-up (PMCF) study is to provide clinical data for the long-term performance and safety when implanted with the Bonebridge BCI 602 .
The purpose of this study is to assess listening effort during a speech-in-noise task in bone-anchored hearing systems (BAHS) users via pupillometry.
The purpose of this study is to assess the efficacity of N-acetylcystein against Cisplatin-induced ototoxicity.
The study will involve the comparison of three groups with severe-profound hearing loss. Patients with a Cochlear Implant only, patients with a cochlear implant and Hearing Aid, and finally patients with two hearing aids. This will enable a comparison of standard fitting protocols against the new rationale using the same devices. Devices used for patients in all 3 groups are now available in standard of care, and can be kept afterwards should the patients wish.
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 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
The clinical investigation is evaluating a new clinical model in a group of newly implanted subjects who have already been consented to CI surgery.
This study investigated the impact of Automatic Sound Management 3.0 (i.e. ambient noise reduction, transient noise reduction and an adaptive intelligence) as implemented in the SONNET2 on CI users' speech performance and their subjective quality of hearing and device handling.
