Filter by:The population in rural Alaska, which is predominately Alaska Native, experiences a disproportionately high burden of hearing loss compared to the general US population. The impact of untreated hearing loss in early childhood is tremendous and has grave implications for school achievement. Preschool children with hearing loss experience speech and language delays and are less likely to be ready for kindergarten than their normal-hearing peers. Early identification and treatment can reverse these ill effects. Importantly, the majority of hearing loss in this age group in rural Alaska is infection-mediated, arising from acute and chronic otitis media that is treatable. In response, preschool hearing screening is federally mandated at all Head Start centers across the country. In accordance with this mandate, hearing screening is already performed by the three organizations that offer early childhood education in the Norton Sound region: Kawerak Inc, RurAL CAP, and Bering Strait School District. While the concept of screening in this age group is well established nationally, what is less well understood is the optimal screening protocol for preschool children. There is little evidence evaluating sensitivity and specificity of different screening protocols in this age group. Further, loss to follow up in the referral stage is a problem in preschool hearing screening just as it is in school hearing screening. Alaska has already developed innovative strategies to address hearing loss. A network of village health clinics staffed by community health aides provide local care, and telemedicine has been adopted in over 250 village clinics statewide. Despite being widely available, telemedicine has not yet been used to speed up the referral process for preventive services such as hearing screening. Norton Sound Health Corporation has partnered with Duke and Johns Hopkins Universities to evaluate hearing screening and referral processes in early childhood education in the Norton Sound region of northwest Alaska. Preschool children will receive screening from the preschool and a new mHealth screening protocol. These will be compared against a benchmark audiometric assessment to determine sensitivity and specificity. Communities will then be randomized to continue the current primary care referral process or to adopt telemedicine referral. The primary outcome will be time to ICD-10 ear/hearing diagnosis. Secondary outcomes will include sensitivity and specificity of screening protocols and prevalence of hearing loss. The goal of this study is to evaluate the optimal screening and referral strategy for preschool children in rural Alaska.
Find a personal sound amplification device that can help people hear better.
This is a phase 1/2 study of FX-322 at two dose levels compared to placebo in male and female adults otherwise healthy with stable sensorineural hearing loss.
Acceptance of CP950 sound processor with experienced CP810/CP910/CP920 BTE sound processor users.
Primary objective of the study is to assess the efficacy of SENS-401 on hearing loss in comparison to placebo at the end of the 4-week treatment period
Aim 1: Establish the feasibility of screening for hearing loss in the ED Aim 2: Determine the acceptability of the screening procedure (among the ED population) Aim 3: Derive a preliminary estimate of the effect size of primary outcomes Aim 4: Identify the evidence that decision makers in Veteran Affair Medical Centers, ED and Audiology Services need to commit to this approach
Patients with unilateral transmission hypoacusis due to otosclerosis undergoing stapedectomy surgery will be prospectively included. They will be undergoing a free field vocal audiometry using the Oldenburg MATRIX software to evaluated the squelch effect gain between audiometry before and after 9months after surgery. Our hypothesis is to show a squelch effect with the rehabilitation of the binaural audition.
This study aims to determine the effectiveness of computer games to improve language and literacy outcomes for children who have hearing loss. Children will be assigned to one of four conditions: phonological awareness training, working memory training, phonological awareness + working memory training, or active control.
An EEG study using continuous speech stimuli to assess neural language processing in a hearing impaired population. Participants listen to short radio excerpts in different Signal to Noise Ratios (SNR) and answer comprehension questions as well as listening effort questions. We assess the effect of different algorithms on neural language processing as well as subjective listening effort. Each participant hears 12 randomized segments of speech (about 4min long each) with different settings on their hearing aid (reference condition, noise reduction algorithm, beam forming algorithm). This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.
Pomegranate has anti-oxidative capacity. It might reduce symptoms of Alzheimer's disease, Drug-induced hepatitis, and might prevent deterioration of cardiovascular diseases and cancer progression. But, the beneficial effects of pomegranate on hearing impairment was still unclear. This study aimed to investigate the beneficial effects of pomegranate on hearing impairment by a prospective, randomized, double-blinded clinical trial design. The investigators'll include 120 elderly patients without hemodialysis in our hospital, and divided them into 2 groups. Control group will receive placebo treatment; pomegranate group will receive oral pomegranate (500 mg, twice per day). All patients received the above treatment for 9 months, and underwent pure tone audiometry and word discrimination scores before the start of the clinical trial and at the end of the treatment (9th month).
