Within the course of this study, a signal processing feature has been developed at Ecole Polytechnique Fédérale de Lausanne (EPFL), in collaboration with Sonova AG, in order to enhance the listening experience with remote microphone systems. In particular, the developed feature is supposed to improve the so-called audio-visual fusion, i.e. the fact to perceive the sound as coming from the physical location of the source. One of the main goals of the present study is to evaluate the extent to which this feature reaches that objective.
In this study the investigators will examine the effects of core stabilization exercises on respiratory muscle strength, respiratory functions and postural control in hearing-impaired children.
Diabetes is now the most common chronic disease, affecting nearly 6% of the population in Western populations. Diabetic neuropathy is a priori the most common and the most common specific complications of diabetes. It can of course touch the lower limbs, the vegetative nervous system as well as the cranial nerves. However, the association between hearing impairment and diabetes has always been controversial on the basis of conflicting literature data. Are auditory disorders an underestimated complication of diabetes? A meta-analysis made in 2013, examined the scientific literature between 1950 and 2011 and of the 3158 citations, only 13 articles were selected. This study found that hearing impairment in diabetic patients was 2.1 times more prevalent than in non-diabetic matched subjects. In addition, the age / aging factor is associated with the prevalence of hearing loss and diabetes. However, it also appears that the link between diabetes and hearing impairment is more pronounced among young people than older people. In order to document the influence of diabetic pathology on hearing, Investigator have set up a search audiological exploration platform within the department of Endocrinology-Diabetology of Clermont-Ferrand University Hospital. It will be proposed a hearing screening (duration 30 minutes) and a questionnaire to diabetic patients of the service. In the context of a positive screening, that is to say that one of the tests carried out reveals the presence of a hearing disorder, an in-depth assessment of the hearing will be carried out to better characterize the origin of the auditory disturbance (duration 60-90 minutes). These different tests are based on the listening of sounds requiring or not the participation of patient. Thus, the results of the various tests will make it possible to classify the impairment of hearing in (1) peripheral impairment (dysfunction of certain cells of your ear involved in the amplification of sounds), and / or (2) in neural damage (dysfunction of your auditory nerve).
The purpose of this project is to validate a quick, easy-to-use and administer smartphone hearing-in-noise test. The Hearing-in-Noise Test (HINT) measures an individual's ability to hear speech in quiet and in noise. HINTs are traditionally done testing both ears together as binaural hearing ability is key in noisy settings and everyday, functional hearing. The app (called HearMe) can potentially be used to easily and quickly collect hearing-in-noise and speech-in-noise measurements. The smartphone app developed is a hearing-in-noise test that presents the subject with a series of stimuli consisting of a spoken three-digit sequence presented at a varying hearing-to-noise ratio. For each stimulus presentation, the user tap the three-digit sequence. The duration of the app is less than 3 minutes. For this project the investigators will test at least 50 subjects with hearing loss and 50 control subjects between the ages of 18-80. The subjects will be invited to take the app. The approach for this pilot study is to characterize hearing-in-noise thresholds (also referred to as a speech-reception threshold) as measured by the app in both subject groups, and relate it to the phenotype of each group as a preliminary evaluation of the app as well as a preliminary validation against their routinely collected measurements of hearing function (pure-tone audiometry thresholds). The study will assess the validity of the test construct in measuring hearing-in-noise thresholds, and serve as a foundation for further iterative designs of the app and future validation and characterization studies. This study seeks to validate a developed smartphone HINT on an initial cohort of patients and controls. It is anticipated that patients with hearing loss will display higher signal-to-noise ratio thresholds (as measured by the iPhone app) compared to controls.
Background: Researchers want to learn more about head and neck disorders. Understanding these disorders could help them find better treatments. To do this, they are collecting tissue samples for research. Objective: To create a repository of tissue samples and data to better study conditions of the head and neck. Eligibility: People who had or will have tissue samples taken because of a head or neck disorder. They must be ages 3 and older and not pregnant to join Part 2. Design: Participants will be screened with a questionnaire, medical history, and physical exam. Part 1. Participants will give permission for any of their tissue samples leftover from private care or other research protocols to be used. If participants tissue did not contain normal tissue or if they have a condition that suggests a genetic issue, they will be invited to join Part 2. Part 2: Participants will have additional samples collected. These could be: - Blood: Blood is drawn through a needle in the arm. - Cheek swab or brushing: A cotton swab or small brush is rubbed inside the cheek. - Saliva: They rinse their mouth with water and spit into a tube or cup. - Skin biopsy: They are injected with a numbing drug. A biopsy tool removes a small piece of skin. - Mucosal biopsy: They are injected in the mouth with a numbing medication. A small piece of tissue from the inside of the cheek is removed. Participants samples will be used for future research, including genetic testing.
Purpose: Routine clinical care and pilot study data has shown evidence of postoperative hearing preservation in pediatric cochlear implant (CI) recipients. The primary aim of this study is to investigate speech perception performance in pediatric CI recipients with functional pre-operative hearing. Participants: Two cohorts of CI recipients aged 6 through 17 years who had pre-operative low frequency residual hearing. Subjects in Arm 1 will present with a post-operative low frequency pure tone average (125, 250, and 500 Hz) of ≤ 75 dB HL, and those in Arm 2 will present with a post-operative low frequency pure tone average (LFPTA) that exceeds 75 dB HL. Procedures (methods): Subjects will complete speech perception and quality of life testing during post-operative intervals. Subjects in Arm 1 will be evaluated with the hearing aid alone (HA-alone) and with combined electric-acoustic stimulation (EAS). Subjects in Arm 2 will be evaluated with the CI-alone.
Background: Cisplatin is a chemotherapy drug. It is used to treat head and neck squamous cell carcinoma (HNSCC) and other cancers. It can cause hearing loss for some people. It is not known how many people will get hearing loss from cisplatin. It is also not known what other factors might influence who gets hearing loss. Factors could include age, sex, noise exposure, and other drugs the person is taking. Statins are drugs used to lower cholesterol. Statins may also reduce cisplatin-induced hearing loss. Objectives: To see if statins reduce hearing loss in people getting cisplatin therapy to treat HNSCC. To find out how many people taking cisplatin get hearing loss from it. To find out if other factors might influence whether cisplatin causes hearing loss. Eligibility: People ages 18 and older who are getting treatment with cisplatin for HNSCC Design: Participants will be screened with a review of their medical records. Participants will have 3 visits. These will be before the onset of cisplatin therapy, at about 4 weeks after they finish therapy, and about 6 months after they finish therapy. Each visit will include: Medication history Audiogram/hearing tests. Participants will wear headphones and indicate when they hear different sounds. Questions about their noise exposure history and whether they have ringing in the ears
The purpose of this feasibility study is to evaluate the benefit of unilateral implantation in adults who have severe to profound sensorineural hearing loss in one ear, and up to moderate sensorineural hearing loss in the other ear (asymmetric hearing loss).
The objective of this study is to compare remote and in-person audiological cochlear implant candidacy evaluations (including audiological (hearing) testing and counseling sessions) in a rural Appalachian region.
