Filter by:Hearing loss is the second most prevalent service-connected disability among Veterans. Hearing aids are the most common technological intervention for hearing loss. The VA, therefore, spends a considerable amount of money on them. Despite these expenditures, there are some Veterans who do not use their hearing aids successfully. Research has demonstrated that this inconsistent use may be related to a patient's inability to effectively take care of, and use, hearing aids. The proposed investigation will compare the effectiveness of three different tools for enhancing the educational efforts (hearing-aid orientation) typically provided by clinical audiologists when dispensing hearing aids. Each of these educational tools were developed using established methods for improving patient-provider communication. The investigators hypothesize that the use of these tools will result in better hearing-aid outcomes for Veteran patients than using the current standard-of-care procedures.
Hearing loss is the most common sensory congenital disorder and this condition is diagnosable and treatable. Children that are born with hearing loss have to undergo several hearing tests to diagnose the condition and many families are delayed in receiving this testing or never obtain the needed testing. This research employs a new method for helping children with hearing loss receive timely care by using a patient navigator, who is someone who teaches and provides emotional/social support for the families of these children. The hypothesis of this study is that a patient navigator will hasten the timing of pediatric audiological testing, improve compliance with scheduled appointments, and expand parental knowledge of pediatric hearing loss.
A double-blind randomised active-controlled trial aims to assess whether Cogmed (adaptive) working memory training results in improvements in untrained measures of cognition, speech perception and self-reported hearing abilities in older adults (50-74 years) with mild-moderate hearing loss who are existing hearing aid users, compared with an active placebo Cogmed (non-adaptive) control. It is hypothesised that improvements on trained Cogmed tasks, representing increased working memory capacity, will result in improved performance on cognitive and speech perception tasks that engage working memory. We also measure self-reported hearing ability to assess self-perceived benefit of Cogmed training.
The purpose of this clinical study is to validate the comparability of prescription formula fitting of hearing aids based on full diagnostic audiometry and SelfFit interactive fitting of hearing aids based on hearing loss screening (mild to moderate hearing losses) using in-situ audiometry, provided and executed through the mobile medical app.
The purpose of this program of research is to understand the perception of the dynamic spectral properties of speech by hearing-impaired listeners, with the long-term goal of improving speech understanding by these individuals in adverse listening conditions. The proposed research compares the performance of normally-hearing and hearing-impaired listeners on measures of speech understanding in the presence of different types of signal distortion and speech understanding of signals with enhanced spectral dynamics. A computational model based on the amount of potential information available in speech will be used to quantify differences in speech intelligibility due to hearing status and stimulus characteristics.
Clinical study to evaluate the safety and efficacy of the Cochlearâ„¢ Nucleus® CI422 cochlear implant for new cochlear implant adult recipients with broader requirements to be considered an eligible candidate.
Randomized post market study comparing Lyric to Lyric2 capturing information regarding comparative performance and safety.
The Bonebridge is a new bone conducting implantable hearing aid. The investigators plan to randomize patients to receive either the Bonebridge or a conventional bone conducting hearing device. The investigators will then compare the surgical and audiological outcomes of the two groups.
The University of Sao Paulo Department of Otorhinolaryngology developed prototypes for a digital new hearing aid with an integrated sound generator. These prototypes assist both hearing rehabilitation (about 10% of the population) and tinnitus sufferers (about 17% of the population). Currently, the Brazilian Public Heath Care does not have any such hearing aids. So, the development of devices for the hearing rehabilitation as well as the treatment of tinnitus represents an advance in the implementation of Public Policies in Brazil. The aim of this study is to compare the efficacy of the hearing aid with an integrated sound generator and amplification alone for tinnitus control in patients with tinnitus associated hearing loss.
The purpose of the study was to evaluate the features of the Nucleus 6 Sound Processor (CP900 series) on existing Nucleus recipients who currently use the previous generation sound processor, the Cochlear Nucleus CP810 (also commonly known as the Nucleus 5), with a Cochlear Nucleus CI24RE, CI512 or CI422 cochlear implant. The features evaluated included an enhanced Automatic Gain Control (eAGC), the option to provide acoustic amplification in combination with traditional electric stimulation through an acoustic component, and three input processing algorithms: Signal to Noise Ratio - Noise Canceller (SNR-NC), Wind Noise Reduction (WNR) and Automatic Scene Analyzer (SCAN). As is customary for a single-subject research design, study results will be analyzed for each subject individually. For evaluations where testing took place under two conditions (i.e. Endpoint 2, 3, 4, and 5) a non-inferiority hypothesis test based on the paired comparisons of the % of words correct will be performed. For each subject, the paired difference (P1 minus P2) will be calculated and the mean difference will be tested statistically against a non-inferiority null hypothesis of 10%. Successful rejection of the null hypothesis allows for a conclusion that the performance under the test condition 2 (based on the Nucleus 6 sound processor) will be non-inferior to the test condition 1 (based on the Nucleus 5 sound processor). Ho: P1 - P2 ≥ 10% Ha: P1 - P2 < 10% We hypothesize acceptance of the null hypothesis for the Nucleus 6 features. Testing will be based on a paired t-test with a one-sided 0.05 alpha level. The value of 10% was selected as the non-inferiority margin as one that can be tested with reasonable power and was clinically meaningful.
