Verification of the Efficacy/Safety of the Intratympanic Drug Delivery for Hearing Loss
Hearing LossSudden5 moreThis study is a prospective, randomized pilot study. To verify an efficacy and safety of the Intratympanic drug delivery vehicle, patients who have not responded to the existing standard treatment will be enrolled. Hearing test, endoscopy of tympanic membrane and CT scans will be conducted after intratympanic treatment for evaluation.
Apple Hearing Study
Hearing LossNoise-Induced1 moreThe Apple Hearing Study is a partnership between the University of Michigan and Apple to study sound exposure and its impact on hearing health. This groundbreaking study will advance the understanding of how hearing could be impacted over time by exposure to sound at certain levels. The investigators will measure headphone and environmental sound exposures over time among participants, and determine how these exposures impact hearing and stress levels. US residents who own an iPhone, download the Apple Research app and consent to participate will be randomly assigned to two groups, one with a "Basic" user interface in the Research app, and one with an "Advanced" user interface. Users in the "Advanced" group will receive additional information about their exposures and be given additional surveys and hearing tests based on their music and environmental sound exposures. The study will provide investigators with a better understanding of listening behavior and its overall impact on hearing health. This information will in turn help guide public health policy and prevention programs designed to protect and promote hearing health in the US and globally.
The Effect of Acupuncture on Patients With Noise-induced Hearing Loss
ElectroacupunctureNoise Induced Hearing Loss2 moreIn an era of advanced industry and commerce, working in a noisy environment is one of the most important risk factors for hearing damage, especially among young and middle-aged people. Although acupuncture has been widely used to treat otology-related diseases, such as tinnitus, dizziness, and sudden deafness, there are few studies on the effect of noise-induced hearing loss.
Understanding the Consequences of Recreational Noise Exposure
Hearing LossHearing Loss1 moreThe aim of this study is to determine whether measures derived from Magnetic Resonance Imaging (MRI) scans, and clinical and behavioural measures of hearing loss, in the peripheral and central auditory system (ranging from the cochlear nerve through the auditory brainstem to the auditory cortex) are associated with age and history of noise exposure in otherwise healthy adult humans.
Preschool Hearing Screening
Hearing LossHearing Disorders in Children12 moreChildren who are deaf or hard-of-hearing (D/HH) are at risk of speech and language delays, which can be mitigated through early identification and intervention. Identifying hearing loss (HL) during preschool is crucial, but the most effective hearing screening method for preschoolers remains uncertain. The purpose of this study is to learn whether, compared to the gold-standard two-stage Pure-tone audiometry (PTA) + otoacoustic emissions (OAE) screening (TS-PO), single-stage OAE (SS-O) screening alone is not inferior at identifying hearing loss when performed in a community-based preschool setting. This study holds the potential to improve early hearing loss detection and intervention among D/HH children, reducing the likelihood of speech and language delays. A diverse group of 28,000 preschool-age children across community-based preschool centers will be recruited. The intervention involves all subjects undergoing both PTA and OAE screening, with the order determined through randomization. Children who show potential hearing issues based on screening results or teacher concerns will receive further testing to determine the final hearing outcome. Group allocation will be post-hoc, based on their screening results. In addition to the primary objective, the study will compare other hearing screening measures and outcomes between the two methods (TS-PO and SS-O). This approach aims to reflect the real-life effectiveness of hearing screening in a diverse population. Ultimately, the study seeks to provide insights into an optimal hearing screening method that could prevent speech and language delays among D/HH children.
Three-dimensional Perception of Sounds in Military With Acoustic Trauma
Hearing LossSpatial hearing capacities of soldiers with acoustic trauma are evaluated in ENT consultations with routine tests (i.e. tonal audiometry, voice audiometry). While the results conclude that soldiers with acoustic trauma have sufficient abilities to carry out professional missions, soldiers report recurring complaints of sound localization (spatial hearing), i.e. difficulties in identifying the position of sound sources in their environment. However, there is currently no objective test to identify and objectify these complaints of spatial hearing. The investigators have developed a new approach (SPHERE) based on virtual reality and 3D motion tracking, allowing us to evaluate and record the spatial hearing performance of subject with hearing deficit. This system allowed us to highlight localization deficits in three-dimensional space. This project explores and quantifies the spatial hearing impairments of soldiers with acoustic trauma. The quantification of the spatial hearing capacities will allow to define a specific rehabilitation strategy of spatial hearing deficits.
Study of Diagnostic Biomarkers of Acute Acoustic Trauma
Acoustic TraumaEvery year, more than two thousand acute acoustic trauma occur in France, equally between the military and the civilian environment. Currently, acute acoustic trauma is a pathology with no specific validated treatment, and it is the cause of many handicapping situations. Improving the future of patients requires a better understanding of the neurophysiological mechanisms of noise-induced hearing impairment. They are multiple and pure tone audiometry, the only reference examination, does not allow to differentiate them. Moreover, in the aftermath of acute acoustic trauma, pure tone audiometry tends to improve spontaneously, but this recovery is misleading, as a number of studies in animals have shown that irreversible lesions remain. The hypothesis of this study is that it is possible to identify new entities, specific to the type of cochlear lesions, in order to clarify the diagnosis of acute acoustic trauma. These entities will be identified by the evaluation of noise-induced hearing impairment via a combination of molecular (proteomic and genomic), physiological and behavioral data. These diagnostic details may then be used to improve prevention or therapy.

FX-322 in Adults With Severe Sensorineural Hearing Loss
Hearing LossSensorineural2 moreThis is a Phase 1b, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter, safety study of FX-322, administered by intratympanic injection, in adults with severe sensorineural hearing loss.
Noise Exposure and Near-Infrared Light
Hearing LossNoise-InducedThe 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.
