Filter by:Children 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.
The goal of this observational study is to learn about effects of noise in healthy patients undergoing elective surgery.
In 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.
Spatial 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.
This is a Phase 2, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter study to evaluate the efficacy of FX-322, administered by intratympanic injection, in adults with acquired sensorineural hearing loss (SNHL).
The 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.
Every 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.
Each year, military epidemiological surveillance counts approximately 1,000 acute acoustic injuries. Most are caused by exposure to weapon noise during training sessions while military personnel are provided with hearing protection. Several hypotheses could explain the occurrence of acute acoustic trauma despite wearing protections: - A lack of practices or knowledge about the use of hearing protection equipment that could facilitate the occurrence of acute acoustic trauma (improper fitting, use of an inappropriate type of protection, dropping of protectors, inappropriate removal) - A failure to seal the external ear canal due to an inappropriate plug size. These hypotheses will be explored using a questionnaire distributed to a population of Army soldiers training to shoot. The main objective is to determine the predictive factors corresponding to practices or knowledge related to the use of hearing protection equipment in the occurrence of acute acoustic trauma in a population of Army soldiers.
The purpose of this study is to assess the safety and efficacy of zonisamide (ZNS) for the treatment of noise-induced hearing loss in adults.
