Active clinical trials for "Deafness"

The purpose of this research study is to learn about the hearing outcomes of adult and pediatric patients who are treated with or are candidates for bone conductive devices (also termed "BAHA"). Hearing outcomes will also be assessed with a second audio processor device called the Adhear System.

This is a prospective, 1:1 randomized controlled trial of immediate versus delayed cochlear implantation (CI) on hearing handicap, communicative function, loneliness, mental wellbeing, and cognitive functioning. Participants are randomized 1:1 to an immediate cochlear implant intervention group versus a hearing aid control intervention.

The purpose of this study is to determine the feasibility of preserving low-frequency acoustic hearing in adults with a moderate degree of hearing loss in the low frequencies and severe-to-profound hearing loss in the mid-to-high frequencies who are implanted with the HiRes™ 90K Advantage implant with HiFocus™ Mid-Scala electrode.

The purpose of this feasibility study is to evaluate whether low-frequency acoustic hearing sensitivity can be preserved in newly implanted adults with partial deafness (considerable low frequency acoustic hearing profiles with severe-to-profound high frequency sensorineural hearing loss) using the HiResolution™ 90K™ Advantage cochlear implant with the HiFocus™ Mid-Scala electrode to support the development of electro-acoustic stimulation technology (EAS).

The stimuli consist of speech in quiet, speech in noise, reverberant speech, and music recorded with different hearing aid settings, post-processed for headphone presentation and incorporated in an online sound survey. Participants will receive tablets and headphones to conduct a sound quality rating at home. The survey will involve a training session and within-subject repeated measures. Stimuli will be randomized.

Assessment of children by speech auditory brainstem response which is an objective method to study the speech development

The objective of the trial is to investigate whether early treatment with oral valganciclovir of infants with both congenital cytomegalovirus infection and sensorineural hearing loss can prevent progression of hearing loss.

One of the most significant challenges in cochlear implant programming, particularly for very young children and those with an associated pathologies, is the measurement of subjective comfort levels (= C-Subjective). Currently, to define this C-Subjective level, patients are presented with a loudness scale and must indicate whether the sound stimulus, sent via the implant, is soft, comfortable, or loud. The lower and upper stimulation levels must be determined for each electrode in order to program the implant. For many patients this can be difficult due to a lack of auditory experience and confusion between the sensation of sound intensity (weak or loud) and frequency (low or high). A less commonly used but more objective approach to programming upper stimulation levels involves the use of the electrical stapedial reflex threshold (eSRTs) value. eSRTs are a promising measure, given the demonstrated correlation between the threshold that generates a stapedial reflex and the C-subjective level. Furthermore, eSRTs can be recorded in the majority of patients, and can typically be evoked at a comfortable stimulation level i.e. inferior to the uncomfortable level. The main objective of this study is investigate the link between subjective comfort levels (C-subjective levels) and the eSRT.

More than half a billion people globally have hearing loss. Most hearing loss is sensorineural, meaning that the hearing loss is irreversible and requires rehabilitation. The majority of people with hearing loss have mild to moderate degrees, for which the most effective treatment options are hearing aids. Over the past few years, there have been many developments in hearing technology and the service delivery models in which they are supplied. Traditional hearing care models include several visits to a qualified hearing professional who must both perform diagnostics and prescribe hearing aids, which in the past has been the only way to obtain hearing aids. However, newer developments include forms of self-fitting hearing aids that enable a user to perform threshold measurements to determine the degree of hearing loss and automatically program and fine-tune hearing aids. These devices are now becoming available as direct-to-consumer (DTC) or over-the-counter (OTC) hearing aids. Furthermore, alternative care models have been suggested to bolster access and uptake of assistive technology for hearing loss. Regulations on DTC and OTC hearing aids are starting to come into effect. In 2017, the FDA Reauthorization Act of 2016 directed the FDA to create a category for OTC hearing aids for adults with perceived mild-to-moderate hearing loss. In October 2021, the FDA formally proposed a rule to establish the OTC hearing aid category as part of this process. These changes in regulations would mean that soon, many of these self-fitting devices will become available. In response to these changes in service delivery models, the hearX group recently developed the Lexie Lumen hearing aids that can perform in-situ hearing threshold estimations and automatically prescribe hearing aid gain settings that closely approximate the gold-standard NAL-NL2 fitting prescription. This study aims to evaluate whether the performance of the novel Lexie self-test and self-fitting hearing aid is equivalent to the same hearing aid programmed professionally by an audiologist using a professionally obtained audiogram.

Recent studies have reported successful reduction of tinnitus after cochlear implantation (CI) in most CI users, but the mechanisms of reduction and the amount of improvement is not fully understood. Especially, the relative role of peripheral and central auditory pathways is not clearly known. This study assessed the effect of CI electrical stimulation on tinnitus in subjects with unilateral tinnitus related to a single-sided deafness (SSD), and relative contributions of peripheral and central auditory pathways in tinnitus reduction.
