NCT ID: NCT02147847 Completed - Presbycusis Clinical Trials

Computer-Based Auditory Rehabilitation

Start date: April 2015
Phase: N/A
Study type: Interventional

Hearing in noisy environments is a perceptual problem that is ubiquitous in modern industrialized societies. This particular listening context offers a particular challenge to individuals living with hearing impairment (30 million in US alone) even after treatment with hearing aids or cochlear implants. The ability of the brain to extract regularities from the environment and suppress distracting information can be improved with intensive cognitive training. The investigators will test whether the hearing in noise abilities of adults living with hearing impairment can be improved with a cognitive training paradigm.

NCT ID: NCT02045511 Completed - Clinical trials for Personal Communication

The Baltimore HEARS Pilot Study

HEARS
Start date: February 2014
Phase: N/A
Study type: Interventional

The primary purpose of the study is to develop and test the preliminary efficacy of a first-in-kind community-based intervention to provide affordable, accessible and effective hearing health care to low-income, minority older adults.

NCT ID: NCT01950013 Completed - Aging Clinical Trials

At-home Auditory Training Clinical Trial

Training
Start date: July 2013
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the effectiveness of an auditory training program used at home with the subject's own hearing aids.

NCT ID: NCT01815788 Completed - Clinical trials for Mild and Moderate Presbycusis

Evaluation of Efficacy and Patient Acceptance of Sound Amplifier Téo First, in Mild and Moderate Presbycusis Patient 60 Years of Age and Older, With no Previous Hearing Aid

TEO FIRST
Start date: April 2013
Phase: N/A
Study type: Interventional

A personal sound amplifying device (PASP) like Teo First is a wearable electronic product that is not intended to compensate for impaired hearing, but rather is intended for non-hearing impaired consumers to amplify sounds in the environment for a number of reasons, such as for recreational activities. Nevertheless, a lot of mild and moderate impaired hearing people don't want to buy and wear all day a real hearing aid. The goal of our study is to evaluate the benefit of such a device for mild and moderate presbycusis patient 60 years of age and older, with no previous hearing aid.

NCT ID: NCT01788423 Completed - Aging Clinical Trials

Evaluating Hearing Aid Service Delivery Models

Start date: November 2012
Phase: N/A
Study type: Interventional

The purpose of this study is to compare the outcomes for two different hearing-aid delivery models. In one model, the audiologist selects and fits the hearing aid and, in the other model, the consumer does this directly.

NCT ID: NCT01732289 Completed - Presbycusis Clinical Trials

Genetic Study of Age Related Hearing Loss

ARHL
Start date: August 2008
Phase: Phase 0
Study type: Interventional

Age-related hearing loss, or presbyacusis, is one of the most common chronically handicapped conditions for the elderly. Many factors including genetics, diet, diseases, drugs, socioeconomic factors and environmental variables were considered to be related to the development of presbyacusis. Evidences have shown that genetic factors play an important role on presbyacusis. However, which genes or their genotypes are associated with presbycusis remain unknown. The aim of this project was to evaluate the association between the genotype of candidate genes and presbyacusis by cross-section and case-control study. In the first stage, the investigators plan to select 700 healthy subjects older than 50 with symmetric, sensorineural hearing loss. The subjects will receive basic otologic examination, pure tone audiometry, questionnaire, and genotype analysis. Because gender and age would affect hearing loss significantly, The investigators will convert the hearing level of all subjects into a gender and age independent Z-score according to ISO 7029 standard. And, The investigators define subjects within higher 30 % of Z-score as the presbyacusis group, and subjects within lower 30% of Z-score as the control group. Finally, The investigators perform Chi square analysis to test the association between genotype of candidate genes or their combinations in both groups, and calculate the odds ratio for presbyacusis between different genotype of candidate genes. Further more, we will evaluate the effect of genotype of candidate genes, environment factors, and gene-environmental interaction on the severity of presbyacusis by multivariate logistic regression. In the second stage, The investigators wish to know the pattern of genotype and hearing level in the high risk families, according to results from the first stage, by description and case-control study. The investigators will perform t-test to evaluate the difference of Z-score in both groups. Besides, The investigators try to evaluate the effects of genotypes, environment factors, and gene-environmental interaction on hearing level in high risk families by multivariate logistic regression.

NCT ID: NCT00488007 Completed - Alzheimer Disease Clinical Trials

Clinical Trial on Alzheimer Disease, Presbycusis and Hearing Aids

Start date: May 2007
Phase: N/A
Study type: Interventional

This is a 12-months' randomized clinical trial that aims at studying the benefit of bilateral hearing aids in hearing impaired patients suffering from a slight to moderate stage Alzheimer disease. The benefit of this intervention will be studied in the cognitive, behavioural, quality of life and economic fields. 2groups are involved in this trial: Intervention group: 12 months' treatment with active hearing aids, fitted hearing impairment Control group: 6 months' treatment with placebo hearing aids, followed with 6 months' active hearing aids, fitted hearing impairment

NCT ID: NCT00371449 Completed - Hearing Loss Clinical Trials

Predicting Success With Hearing Aids

Start date: November 2006
Phase: N/A
Study type: Observational

The primary complaint of individuals with hearing loss is difficulty understanding speech in the presence of background noise. Although hearing aids help individuals understand speech in background noise better, there is a high rate of hearing aid rejection in part due to continued difficulty understanding speech in complex listening situations. The results of this study may demonstrate that speech-in-noise test results can be a predictor of hearing aid success. The results of this study also may lead to further studies that can evaluate interventions to improve hearing aid success for individuals who are identified as unsuccessful hearing aid users.
