Active clinical trials for "Hearing Loss"

Children with special needs require complex, individualized therapy to maximize their long-term quality of life. One subset of children with special needs includes those with both developmental delays and deafness. Currently, there is little compelling evidence supporting the idea that cochlear implantation provides benefit to children that don't have the cognitive potential to develop normal speech and language. We will perform a prospective, randomized clinical trial to answer the question of which intervention provides more benefit to this population of children using validated, norm-referenced tests. Our long-term goal is to develop guidelines that may help when selecting a treatment for hearing loss in a child with developmental delays. This proposal is significant because children with special needs are deserving of evidence upon which to base treatment decision-making, but remain under-represented in the medical literature and are often not studied. This research is designed to meet the criteria for the National Institutes of Health road map because it will generate this type of objective evidence that can directly improve patient care.

The purpose of this study is to investigate if sound stimulation could improve pure-tone hearing threshold. In the late 1990s, researchers discovered that acoustic stimuli slow progressive sensorineural hearing loss and exposure to a moderately augmented acoustic environment can delay the loss of auditory function. In addition, prolonged exposure to an augmented acoustic environment could improve age-related auditory changes. These ameliorative effects were shown in several types of mouse strains, as long as the acoustic environment was provided prior to the occurrence of severe hearing loss. In addition to delaying progressive hearing loss, acoustic stimuli could also protect hearing ability against damage by traumatic noise. In particular, a method called forward sound conditioning (i.e., prior exposure to moderate levels of sound) has been shown to reduce noise-induced hearing impairment in a number of mammalian species, including humans. Interestingly, recent report has suggested that low-level sound conditioning also reduces free radical-induced damage to hair cells, increases antioxidant enzyme activity, and reduces Cox-2 expression in cochlea, and can enhance cochlear sensitivity. Specifically, increased cochlear sensitivity was observed when distortion product otoacoustic emissions (DPOAEs) and compound action potentials (CAPs) were measured. In addition to forward sound conditioning, backward sound conditioning (i.e., the use of acoustic stimuli after exposure to a traumatic noise) has been shown to protect hearing ability against acoustic trauma and to prevent the cortical map reorganization induced by traumatic noise. Based on the results of animal studies, the investigators conducted a human study in 2007 and observed that sound stimulation could improve hearing ability. On average, the pure-tone hearing threshold decreased by 8.91 dB after sound stimulation for 2 weeks. In that study, however, the investigators observed only the hearing threshold changes by sound stimulation. To verify the previous ameliorative effect of sound stimulation, the investigators included a control period in this study.

The purpose of this multi-site randomized clinical study is to test a model treatment program in a VA Audiology clinic, to evaluate its efficacy, ease of implementation, and acceptability to audiologists.

This trial aims to compare the efficacy of oral prednisone vs. methylprednisolone injected into the middle ear for the treatment of moderate-to-severe, sudden sensorineural hearing loss (inner ear hearing loss affecting one ear that occurs over less than 72 hours).

The trial will test whether a standard music program that is an offset to the general program provides the same benefit as a music program that is individually customized for each test participant. The trial seeks to investigate the benefit received by musicians that regularly play an instrument and belong to an organized music group or orchestra instead of people that listen to music.

The purpose of this study is to assess the effect of the Naida Link CROS device on speech understanding in challenging listening situations and on the quality of life in unilateral CI recipients and their frequent communication partners. We hypothesize that: Unilateral CI recipients will obtain higher speech understanding scores with the CROS device in challenging listening conditions Use of the CROS device will lead to positive changes in ratings on Quality of Life measures for (i) unilateral CI recipients, and (ii) their frequent communication partners A frequent communication partner (FCP) is an individual (a family member, or a friend, or a care taker, or a significant other, or a colleague, etc.) who has at least two hours of in-person interactions with the CI recipient every week.

For this study, Bernafon AG will carry out testing with participants with hearing loss to compare a dedicated music program to a general listening program. The Bernafon hearing aids used for the current study are CEmarked and will be released to the market in early 2022. The goal is to determine whether musicians will perceive a difference and prefer the music program over the default listening program in real-life situations. The devices will also be validated for performance before their release to the market.

Cochlear Implantation is a system developed to restore hearing in people with profound sensorineural hearing loss, whose classical hearing aids are ineffective. Surgery is necessary to insert the internal part into the cochlea and requires milling the mastoid to access the round window. This approach is technically difficult, and is performed under a microscope by an experienced surgeon. The development of a surgical technique that is both safer and less invasive is currently possible thanks to robotics.

The aim of this clinical investigation is to collect long-term safety and performance data with the Active Osseointegrated Steady-State Implant System by following subjects from the previous Osia clinical investigation CBAS5751. In addition, questions regarding device satisfaction, sound satisfaction, usability and health care utilisation will be asked.

The primary objective of this work is to determine the effect noise has on the auditory system (both auditory health and performance) and also the degree to which the effect of pre-noise therapy such as Near Infrared (NIR) light can mitigate the effects of noise exposure.
