This research is being done to determine whether a test that measures a "Visual Evoked Potential" can be used in a new way for individuals that have hearing loss. This test measures the participant's brain's response (so called "brain waves") to specific visual images. This study will help the investigators determine whether this test could be used to improve treatments for patients with hearing loss. The "Visual Evoked Potential" measurement test is already used in the investigator's Neurology clinic at Dartmouth Hitchcock Medical Center for various conditions to measure "early" brain responses that occur in the first 1-2 seconds after a new cue. Our research aims to explore your brain's response just after that early 1-2 second period by looking at a specific response called the "P300". The P300 wave is a brain response to new or different images or sounds. A visual evoked P300 has not been studied in individuals with hearing loss. The investigators will compare the results of this test to standard auditory tests, tests of cognitive function, and cochlear implant patient outcomes to explore how these factors can predict successful use of a hearing aid or cochlear implant.
Hearing impairment in older adults is becoming a common health problem as the population ages. The impact of hearing impairment in older adults includes not only physical function and cognitive performance, but also depression, loneliness and social isolation, as well as having a negative impact on quality of life and financial status. Therefore, an audiological rehabilitation program intervention is recommended. The purposes of this study are to examine the effects of an audiological rehabilitation program (Hear-Talk-Activity audiological rehabilitation program) intervention on communication abilities, depression, loneliness and quality of life outcomes in older adults with hearing impairment. The single-blind, randomized control trial will include older adults aged 65 years or older with hearing impairment and aid user. Participants will be randomized to either intervention groups or control groups.
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.
The objective of this study is to validate the User-operated Audiometry (UAud) system for user-operated audiometry in a clinical setting, by investigating if hearing rehabilitation based on UAud is non-inferior to hearing rehabilitation based on traditional audiometry, and whether thresholds obtained with the user-operated version of the Audible Contrast Threshold (ACT) test correlates to traditional measures of speech intelligibility.
HearVA involves six VA facility emergency departments (ED) over a 3-year intervention period. The first part of this study will test whether providing personal amplifiers to Veteran ED patients who self-report hearing difficulty is acceptable to these patients, can improve their hearing, enhance understanding of discharge instructions, and can reduce the risk of coming back to the ED in a short period of time (3 days and 30 days). The second part of the study will then identify whether ED staff can implement this program and achieve similar results. The second part will give ED staff increasing levels of responsibility for screening Veterans for hearing difficulty and providing personal amplifiers when such difficulty is detected.
This feasibility study is designed to explore several facets of hearing performance that may show improvements for alternative modes of stimulation compared to Monopolar (MP) stimulation within a group of adult cochlear-implant recipients. Measures of speech recognition, music appreciation, listening effort, quality of life, and real-world assessments will be gathered to determine the most promising benefits for further examination.
This study examines the development of American Sign Language by deaf and hard of hearing (DHH) children and their parents.
The research aims to address to address the role of interdisciplinary working between professionals in the field of speech and language pathology/therapy. There is considerable evidence to state that when professionals work in collaboration with each other on particular goals that the outcomes are more favorable, functional and beneficial for the child.
Phase I clinical study on the safety, tolerance, efficacy and pharmacokinetics of repeated intratympanic HY01 in patients with sudden sensorineural hearing loss. In this study, low-dose group and high-dose group were designed, 6 cases in each group.
