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.

There are few or no questionnaires in French on the hearing quality of life of children with hearing aids. The objectives of the study are to measure the hearing quality of life of children with hearing aid and / or cochlear implants and to compare the hearing quality of life according to the type of hearing aid (hearing aid and / or cochlear implant).

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 purpose of this study, which contains a series of successive study parts, is to methodically evaluate Phonak Hearing Systems on hard of hearing participants to grant quality control prior to each product launch.

Within the course of this study, a signal processing feature has been developed at Ecole Polytechnique Fédérale de Lausanne (EPFL), in collaboration with Sonova AG, in order to enhance the listening experience with remote microphone systems. In particular, the developed feature is supposed to improve the so-called audio-visual fusion, i.e. the fact to perceive the sound as coming from the physical location of the source. One of the main goals of the present study is to evaluate the extent to which this feature reaches that objective.

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.

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.
