Filter by:Quality and reliability study of hearing aid. Adults with mild to severe hearing loss will wear hearing aids daily for approximately 3 months.
Clinical management of cochlear implant (CI) recipients involve programming, counselling, performance evaluation and habilitation. This requires the recipients to travel to the clinic for follow up appointments which can pose significant challenges for recipients, particularly those who live far away from the clinic. Remote Assist (RA) is a new solution that allows the clinician to make MAP and sound processor adjustments via the recipient's Nucleus Smart app (NSA) installed on their smart phone. With RA the clinician can also perform counselling using a video call directly via the NSA. As RA uses no specialized hardware and software that needs to be sent and retrieved back from the recipient, it has the potential to further improve the remote programming experience and convenience for both the recipient and the clinician.
This study will evaluate the impact of hearing aid microphone directionality technologies and settings on speech understanding in noise for experienced hearing aid users. It will also evaluate the participant's spatial awareness of sounds using these different hearing aid microphone directionality technologies.
For this study, Bernafon AG will carry out testing with participants with hearing loss to compare a dedicated music program to a general listening program. The Bernafon hearing aids used for the current study are CEmarked and will be released to the market in early 2022. The goal is to determine whether musicians will perceive a difference and prefer the music program over the default listening program in real-life situations. The devices will also be validated for performance before their release to the market.
Main objective: Show the superiority of tonotopy based fitting strategy compared to default fitting strategy on the perception speech in noise. Secondary objectives: Show the superiority of tonotopy based fitting strategy compared to default fitting strategy on the perception of musical elements (contour test). Show the non inferiority of tonotopy based fitting strategy compared to default fitting strategy on the perception of speech elements in quiet. Show the superiority of tonotopy based fitting strategy compared to default fitting strategy on the qualitative preference for the listening of musical pieces.
Pilot study done to evaluate the breakdown and and potential utility of a bioabsorbable ventilation ear tube made with gelatin.
Evaluating the efficacy and effectiveness of an advancement in the fitting characteristics of extended wear technology with the commercially available device as a comparator.
Participants will wear one set of 2 different BTE hearing aid models based on the gain required by their hearing loss. The hearing aids will be programmed based on a prescriptive approach and participants will be sent out for either one home trial with the less powerful BTEs or for two home trials with the SP (super power) BTEs.
An intervention group and a control group will complete a battery of questionnaires at four time points to investigate the impact of first-ever hearing aid fitting on fatigue and associated variables. The study is observational as all participants in the intervention group will already be receiving their first-ever hearing aid as part of their routine audiological care.
Tinnitus, the perception of sound in the absence of an external acoustic stimulus. Tinnitus is often perceived inside the head rather than the ear and is a common condition with a prevalence estimated between 10 and 15% in adults. Between 1 and 3% of this population are having a significant impact on their quality of life. Despite its high prevalence, the underlying mechanisms of tinnitus still remain unclear. The majority of tinnitus cases associated with some degree of hearing loss, making hearing loss the biggest risk factor for tinnitus. Recently, it has been suggested that hearing deficits, such as speech-in-noise difficulty, can exist in the absence of any overt hearing loss within the audiometric range (0.125-8 kHz). This is referred to as "hidden hearing loss" and has been suggested to be associated with hearing loss at above-audiometric (> 8 kHz) frequencies. This project is aimed at studying the underlying mechanisms of tinnitus and the possible relation with overt or hidden hearing loss. Specifically, the investigators want to test the hypothesis that tinnitus is caused by maladaptive plasticity arising as a result of auditory input deprivation. This idea is supported by the finding that tinnitus may disappear when the hearing, and thus auditory input, recover. Disruptions at lower levels of the auditory pathway could lead to alterations in synaptic transmission and neurotransmitter release in more central regions of the auditory system (e.g., in the auditory cortex). This may create an imbalance between neuronal excitation and inhibition, and re-routing of auditory pathways, leading to abnormal neural excitability and connectivity. In this study, the investigators question whether auditory cortex disinhibition is specifically related to tinnitus, or is a consequence of hearing loss. To answer this question, the investigators propose to conduct a study that aims to investigate the inhibition mechanism by quantifying GABA concentration level, neural activity and functional connectivity strength of auditory cortex using non-invasive imaging techniques, namely Magnetic Resonance Spectroscopy (MRS) and functional Magnetic Resonance Imaging (fMRI). The investigators expected to possibly provide a tinnitus biomarker, and this may help to direct future treatments.
