NCT07646119
The goal of this observational study is to investigate whether speech-in-noise perception deficits in older adults aged 60 years or older with objectively normal hearing thresholds are due to impaired ability of processing temporal cues in speech signals. The study further aims to examine whether cognitive and cortical mechanisms provide compensatory support for speech perception in challenging listening environments.
NCT07526428
The goal of this interventional study is to evaluate the DNN Noise reduction feature of Phonak hearing aids in adults with moderate to moderate severe hearing loss. The main questions it aims to answer are: Do participants correctly identify significantly more words on the AZBio Sentence Test when using Phonak's DNN NR feature than when using Competitor device A in a lab setting? Do participants subjectively rate the speech clarity, ease of listening, and listening confidence higher when using Phonak's DNN feature than when using Competitor device A in both a lab setting and a real-world cafe setting? Do participants have an overall preference for the Phonak device over the Competitor device A in a real-world cafe setting? Participants will be fit with both the Phonak device and a Competitor device A in the lab. They will be given the AZBio Sentence test and repeat as many words as they can in a simulated noisy environment. Following the lab visit, participants will meet in a group with three other conversation partners in a real-world setting and asked to complete subjective questionnaires during the visit.
NCT06960616
The study is about the importance of each follow-up visit after activating a new cochlear implant in addition to evaluating the effectiveness and efficiency of a new programming strategy from Cochlear Americas. Investigators are looking for patients who have recently selected Cochlear Americas as their cochlear implant manufacturer of choice for their upcoming surgery. The aim of this study is to determine if 1) patient outcomes remain stable when reducing follow-up appointments and 2) Cochlear's population mean mapping can produce similar outcomes with patients while additionally reducing appointment times. The hypothesis is that using population mean mapping and reducing the number of follow-up visits after activation will yield similar performance outcomes to a standard of care while decreasing the length of appointment times and number of appointments needed for each patient.

Data will collect using the "Hearing Loss and Hearing Aid Knowledge and Attitudes Questionnaire Among Faculty of Health Sciences Students," which consisted of 29 items. The One-Way ANOVA test was used to compare quantitative variables between groups.
NCT06354010
The purpose of this study is to characterize and assess the evolution of hearing impairment of patients with adulthood-onset bilateral sensorineural hearing loss carrying mutations on GJB2 gene.
NCT04240561
This current translational project, funded by NIH, aims to better understand the impact of various signal modification strategies for older adults with Alzheimer's dementia and its potential precursor, known as amnestic mild cognitive impairment. The investigators hypothesize that adults with Alzheimer's dementia represent an extreme case of restricted cognitive ability, such that very low working memory capacity and overall reduced cognitive capacity will limit benefit from advanced signal processing. Thus, the investigators hypothesize that adults with Alzheimer's dementia will receive greater benefit from acoustically simple, high-fidelity hearing aid processing that minimally alters the acoustic signal.
NCT05365646
The purpose of this study is to develop and validate methods to use hearing aids equipped with embedded sensors and artificial intelligence to assist in the assessment of fall risk and in the implementation of interventions aimed at reducing the risk of falling, as well as to improve speech intelligibility in quiet and in background noise, track physical activity, and social engagement. The investigators hope is that the knowledge that is generated through this study will ultimately translate to the clinical setting and will help reduce the likelihood that individuals experience a fall, and improve the quality of hearing in individuals who wear hearing aids.
NCT07218913
This phase I trial evaluates whether adding Pedmark to standard of care cisplatin-based chemotherapy reduces drug-induced ear damage (ototoxicity) in men with stage II-III testicular germ cell tumors that have spread from where they first started (primary site) to other places in the body (metastatic). Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Cisplatin-induced ototoxicity remains a major concern in adult patients with germ cell tumors as nearly four out of five patients develop hearing loss after treatment. Cisplatin is thought to cause ear damage by the production of chemically reactive molecules called reactive oxygen species. These molecules can cause damage when their levels get too high. Pedmark may reduce the negative side effects of cisplatin by neutralizing these reactive molecules. Pedmark has been approved for reducing the risk of cisplatin-induced ototoxicity in pediatric patients and older patients with solid tumors that haven't spread to other parts of the body. Adding Pedmark to cisplatin-based chemotherapy treatment may reduce ototoxicity in adult men with stage I-III testicular metastatic germ cell tumors.

This study is a multicenter, single-arm, open-label Phase I/II clinical trial, which is designed to evaluate the safety, tolerability and efficacy of EHT102 injection in treating congenital hearing loss secondary to biallelic mutations of OTOF (DFNB9).Up to 30 pediatric participants (A maximum of 15 participants will be enrolled in each of the United States and China) will be enrolled and dosed with EHT102. The dose-escalation phase (Phase I) includes two predefined dose cohorts (3 participants per cohort), with sequential enrollment from low to high dose. During dose escalation, each participant will receive a unilateral EHT102 injection followed by safety observation.
NCT06782308
The goal of this survey is to assess several aspects related to patient preferences regarding interventions for alleviating tinnitus through invasive electrical brain stimulation (neuromodulation). This survey covers the acceptance of a surgically-placed brain implant, of its associated risks related to the neurosurgical procedure, usability considerations, and the willingness/ability to pay for such a treatment. Neurosoft Bioelectronics will use the collected patients' feedback and usability preferences data for the development of a novel minimally invasive brain implant aimed at alleviating tinnitus.
NCT07505667
This project aims to evaluate the clinical efficacy of Yiyuancong, an independently developed traditional Chinese medicine (TCM) formula based on the homology of medicine and food, in participants with sudden sensorineural hearing loss (SSNHL) and to elucidate its potential underlying mechanisms. This study is designed as a multicenter, randomized controlled trial (RCT), utilizing dynamic randomization for participant allocation. Due to the requirement for the experimental group to continuously administer the TCM preparation for 1-2 months, this study is conducted as an open-label (non-blinded) trial. All participants will undergo audiological evaluations at baseline, day 7 of treatment, and upon completion of the first and second treatment courses. Based on previous research regarding integrated traditional Chinese and Western medicine for SSNHL, the estimated effect size (ES) for the improvement of pure-tone thresholds compared with Western medicine alone ranges from 0.5 to 0.8. Assuming an effect size of 0.5 for the difference in pure-tone audiometry (PTA) improvement between the experimental and control groups, with a significance level (α) of 0.05 (one-tailed) and a statistical power (1-β) of 0.8, the required sample size calculated via G\*Power software is 51 per group. Accounting for a 20% dropout rate, the investigators plan to enroll 64 participants per group (total N = 128).
NCT06734039
The purpose of this study is to evaluate the impact of different audio processor frequency settings on performance outcomes in new cochlear implant users using electric-only stimulation in the implanted ear with normal hearing to moderately severe hearing loss in the opposite ear.
NCT06803394
The objective of this study is to test the effect of a community-delivered, affordable, and accessible hearing care intervention on improving communication function and health-related quality of life among older Korean Americans (KA) and the older Korean American's care partners that integrates a low-cost over-the-counter amplification device and hearing rehabilitation in comparison to a 6-month delayed treatment group through a cluster randomized controlled study.
NCT01781039
Understanding speech is essential for good communication. Individuals with hearing loss and poor speech discrimination often have little success with hearing aids because amplifying sound improves audibility, but not clarity of the speech signal. The purpose of this study is to determine the relative importance of the sensory cells of the inner ear and auditory neurons on speech discrimination performance in quiet and in noise. This information may be used as a predictor of hearing aid benefit. The investigators expect to find decreased speech understanding ability resulting from both loss of sensory cells and the loss of auditory neurons.
NCT04793412
This is a two-phase study that compares performance growth pre-implant with current hearing aid (HA) technology versus post-implant with a cochlear implant (CI) in children with either asymmetric hearing loss (AHL) or single-sided deafness (SSD). Post-implant performance with a CI alone is expected to outperform pre-implant performance with a HA. The study also evaluates the effectiveness of bimodal hearing defined as a CI in the poor ear and a HA in the better ear for AHL or a CI in the poor ear and normal hearing in the better ear for SSD compared to pre-implant performance. The study examines factors contributing to CI outcomes.
NCT07452653
In patients with symmetric hearing loss who meet traditional cochlear implant candidacy criteria yet demonstrate pre-operative unilateral vestibular weakness, the choice of which ear to implant may impact their post-operative vestibular course. The investigators aim to implement both objective videonystagmography metrics as well as subjective patient-reported outcome measures to assess whether selecting laterality for cochlear implantation as it relates to unilateral vestibular loss has a measurable impact on patients' post-operative vestibular function. In pursuing cochlear implantation on the ear that demonstrates worse vestibular function, the investigators hypothesize improved vestibular function in comparison to operating on the unaffected side. The randomized control pilot study plans to allocate 10 subjects to a treatment group that involves cochlear implantation on the ipsilateral side of vestibular hypofunction and a control group that will undergo implantation on the contralateral side. The investigators plan to compare scores derived from the Dizziness Handicap Inventory completed at pre-operative evaluation and at two subsequent post-operative visits between control and treatment groups as primary outcome. The investigators also plan to determine if there is a significant difference in measures derived from caloric vestibular testing pre- and post-operatively as well as between control and treatment groups.
NCT04915183
Background: Cisplatin is used to treat head and neck cancer. People who take this drug are at risk for hearing loss. Atorvastatin is a drug used to treat high cholesterol. It might reduce the risk of cisplatin-induced hearing loss. Objective: To find out if atorvastatin reduces hearing loss in people treated with cisplatin and radiation. Eligibility: People ages 18 and older with squamous cell carcinoma of the head and neck who will undergo treatment with cisplatin-based chemotherapy and radiation Design: Participants will be screened with their medical records. Participants currently taking a cholesterol-lowering statin medication are invited to participate in the observational arm of the study. Those not taking such a medication are invited to participate in the interventional arm of the study. All participants will have 3 study visits for the purpose of evaluating hearing. One before starting cisplatin treatment, one within 3 months of completing cancer treatment, and one within 2 years of completing cancer treatment. They will have tympanograms. A small flexible tip will be placed in the ear canal. A puff of air will be delivered to assess mobility of the ear drum. They will have hearing tests. They will wear headphones. They will listen to tones that vary in loudness. They will be asked to indicate when they hear a sound. They will complete 3 questionnaires at the time of each hearing test. Participants will have 2 visits for blood tests. These will occur upon consent and 12 weeks after. They will be randomly assigned to take the study drug or placebo orally, once daily. They will take it during cisplatin treatment and for 3 months after treatment. Long-term follow up will include a chart review 2 years after participants complete their cisplatin therapy.
