Hearing Aid

The purpose of the study is to investigate the effect of an anatomy-based frequency distribution in comparison to a default frequency distribution in bimodal CI patients, i.e. wearing a cochlear implant and a contralateral hearing aid. Speech perception in quiet, speech perception in noise, consonant/vowel discrimination and pitch/timbre perception will be assessed in an acute set-up with both the default fitting map and the anatomy-based fitting map.

This study aims to examine the knowledge levels and attitudes of students enrolled in departments other than Audiology within the Faculty of Health Sciences regarding hearing loss and the use of hearing aids. This study is a descriptive. The study included students enrolled in the Faculty of Health Sciences at Ondokuz Mayıs University. 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.

Researchers are doing this study to understand why hearing aids often work well in controlled laboratory settings but don't provide the same level of benefit in everyday noisy environments. The questions they hope to answer are: * What factors contribute to hearing aid benefit in noisy environments * What factors limit hearing aid benefit * How do real-world factors interact with common hearing aid settings Participants will complete: * Hearing and listening tests * Memory and attention assessment * Surveys on their Smartphone

The goal of this clinical trial is the evaluation of performances, clinical benefits and safety of the 'Audiocap' connected hearing rehabilitation device for improving audibility in hearing-impaired people. The main question it aims to answer is to demonstrate, after one month's use of the Audiocap connected hearing aid, that the audiological gain for the patient is better than with a placebo hearing aid. Placebo hearing aid is a Audiocap connected hearing aid with a 'NONE' setting (flat frequency response for the patient (equivalent to not wearing hearing aid). Participants will be first-time hearing aid users, eligible for hearing aid fitting, and adults according to French legislation (18 years and older).

The study is designed as an international, multi-center, single-armed, non-interventional/observational study including subjects who has received or are planned to receive the Sentio system as part of normal clinical practice.

The aim of this clinical trial is to evaluate the effectiveness and user satisfaction of remote fine-tuning of hearing aids compared to traditional face-to-face adjustments. The main questions aims to answer: \- Are hearing aid outcomes (self-reported and objective) similar when using remote fine-tuning compared to face-to-face adjustments? Researchers will compare remote fine-tuning (using a smartphone app) to traditional face-to-face fine-tuning sessions in a clinical setting. Participants will: * Be randomized to either the remote fine-tuning group (intervention group) or the face-to-face adjustment group (control group). * Attend five scheduled consultations over a 3-month period, including baseline measurements, hearing aid fittings, and follow-up visits. Participants in the remote fine-tuning group will: \- Set up and use a hearing aid manufacturer's smartphone app to complete fine-tuning sessions from home. Participants in the face-to-face group will: \- Visit the clinic for in-person fine-tuning appointments. Data will be collected through questionnaires (e.g., SSQ-12, IOI-HA, and COSI) and objective measures such as the Speech Intelligibility Index (SII) and speech comprehension in noise (DS-FF). Additional qualitative data will be gathered from interviews with participants in the remote fine-tuning group.

Background: Deafness is one of the nine potentially modifiable risk factors for dementia simulated by the Lancet dementia Prevention, intervention and Care Committee in 2017. Some studies have found that the risk factors of dementia in deafness system, with the increase of the degree of deafness, the risk of cognitive decline increases, while after long-term wear of hearing aids, the deterioration of immediate and delayed memory is less, and the possibility of cognitive decline slows down. Therefore, it is necessary for us to improve the auditory ability of patients with deafness through auditory intervention, so as to slow down its effect on dementia and reduce the incidence of dementia. At present, auditory intervention methods include hearing aid wearing and cochlear implant. However, there are few studies on cognitive function of presbycusis patients in China, and there is no research on how many years of auditory intervention can effectively slow down the incidence of dementia in presbycusis patients with MCI. Therefore, we intend to conduct a prospective cohort study on the changes of cognitive function of presbycusis under hearing aid intervention.
