Active clinical trials for "Hearing Loss"

Purpose: The purpose of this study is 1) to evaluate the safety and efficacy of currently available multichannel cochlear implant systems for newly implanted adults with an indication based on open-set sentence recognition that expand criteria currently used by Center for Medicare & Medicaid Services (CMS), and 2) to assess the correlation between measures of speech recognition in candidates for cochlear implants and their utility in predicting audiologic and quality of life outcomes after implantation. Participants: Adults (≥ 65 years of age) and CMS-eligible as a primary source of medical insurance coverage. Procedures (methods): Evaluate objective and subjective outcomes of cochlear implantation in a patient population that does not meet current CMS candidacy criteria.

Aspirin (ASA) has been shown, in an animal model, to attenuate the ototoxic properties of cisplatin. The researchers plan to investigate this in patients undergoing cisplatin chemotherapy. The researchers hypothesise that low-dose aspirin can prevent cisplatin induced ototoxicity in the clinical setting.

The purpose of this study was to determine the effects of hormone replacement therapy (HRT) on hearing in post-menopausal women.

The effects of talker variability will be investigated with four groups of listeners (young normal-hearing; old normal-hearing; young hearing-impaired; old hearing-impaired). Experimental conditions will include between-talker differences, speaking rate, lexical difficult and semantic/linguistic context. A preliminary experiment will evaluate the relative merit of adaptive vs fixed-level methods of stimulus presentation.

Comfort and clarity of speech will be measured in hearing impaired children age 8-17 using standard speech processing algorithm with a soft speech enhancer feature, referred to as the Adaptive Situational Gain (ASG) feature in study documents.

The specific aim of this research is to evaluate the performance, effectiveness, and long-term training benefits of a formal hearing protection fit testing program. This study may provide preliminary evidence on the benefits of direct education/training combined with a formal hearing protection device (HPD) fit testing on HPD fittings on United States Air Force (USAF) employees. Currently, Public Health provides informal, subjective training to employees; this practice may be altered by the results of this study.

The purpose of this study is to find out whether the High Frequency Digit Triplet test can be used to screen patients with cystic fibrosis for hearing loss in conditions of health and pulmonary exacerbation. It is also designed to find out the youngest age at which a child can perform the test, the prevalence of hearing loss in a CF population and the prevalence of genetic mutations known to be associated with hearing loss in the same population.

This study investigates the use of a new healing cap which, through altered design and choice of material, has been improved when it comes to minimizing the risk of it falling off as well as increasing patient comfort.

The aim of this study is to validate uHear™, an iOS-based tool, as a screening tool to detect significant hearing impairment as part of a comprehensive geriatric assessment in patients aged 70 years and older. The pass or fail screening cut-off is defined as having two or more consecutive hearing grades starting from the moderate-severe threshold zone ranging from 0.5 - 2.0 kHz.

The present study has the evaluation of a test to measure the localization performance goal . It is about the perception of danger audio signals in everyday listening environments nearby which are reproduced in controlled laboratory conditions. In addition, a dereverberation algorithm regarding speech intelligibility and localization ability is evaluated . The research hypothesis is that the dereverberation of the audio signals can improve speech intelligibility for both normal hearing and hearing-impaired persons. In addition, the binaural dereverberation algorithm should not affect the localization ability in everyday situations.
