Evaluation of Hearing Aids Rehabilitation Within Age-related Hearing Loss Population.

Hearing Loss

Hearing aids restore efficiently some auditory functions in age-related hearing loss (ARHL or presbycusis) providing to the elderly an access to oral communication and a return to social life. However, a most of the assessments of their efficacy focus on speech recognition. Spatial hearing and localization are anothers important auditory functions merely evaluated. The purpose of this study is to evaluate the hearing aids benefits for spatial hearing.

Cochlear Implants in Young Children With SSD

Single Sided DeafnessUnilateral Deafness5 more

The goal of this clinical trial is to investigate the safety and effectiveness of cochlear implantation in infants and toddlers with single-sided deafness. The main questions it aims to answer are: Are cochlear implants an effective treatment of single-sided deafness in infants and toddlers? Are cochlear implants a safe treatment for single-sided deafness in infants and toddlers? Participants will receive a cochlear implant and be followed until they are five years old. During those five years, the investigators will program the device and monitor auditory development. Children will be asked to: Undergo cochlear implantation Wear their cochlear implant processor whenever they are awake. Participate in traditional hearing tests Participate in traditional hearing testing Participate in localization testing Participate in hearing in noise testing Participate in word recognition testing Participate in speech, language, and educational evaluations The researchers will compare results to children with typical hearing in both ears and children with single-sided deafness who have not received an implant to observe any differences between the groups.

Teletherapy in Children Who Are Deaf and Hard of Hearing

Hearing LossSpeech and Language Development Delay Due to Hearing Loss

This study seeks to determine the effectiveness of speech/language teletherapy to address disparities in speech and language outcomes in children who are deaf or hard-of-hearing (D/HH). The investigators will enroll D/HH children aged 0-27 months. 140 children who are publicly insured will be randomized to receive usual clinical care or to be given access to an 18-month course of speech-language teletherapy program. 70 children who are privately insured will also be enrolled and will receive usual care. Children will undergo, at baseline and every 9 months thereafter to a study endpoint of 18 months, for a total of 3 timepoints, a battery of in-person and parent-report assessments designed to provide a comprehensive measurement of the child's auditory function, speech, verbal- and non-verbal communication, spoken language, and quality of life.

Quantifying the Benefits and Cost-effectiveness of Real-Ear Measurements (REM) for Hearing Aid Fitting...

Sensorineural Hearing LossBilateral

Adjusting hearing aid user's real ear performance by using probe-microphone technology (real ear measurement, REM) has been a well-known procedure that verifies whether the output of the hearing aid at the eardrum matches the desired prescribed target. Still less than half of audiologists verify hearing aid fitting to match the prescribed target amplification with this technology. Recent studies have demonstrated failures to match the prescribed amplification targets, using exclusively the predictions of the proprietary software. American Speech-Language-Hearing Association (ASHA) and American Academy of Audiology (AAA) have created Best Practice Guidelines that recommend using real-ear measurement (REM) over initial fit approach and also the recent ISO 21388:2020 on hearing aid fitting management recommends the routine use of REM. Still audiologists prefer to rely on the manufacturer's default "first-fit" settings because of the lack of proof over cost-effectiveness and patient outcome in using REM. There are only few publications of varying levels of evidence indicating benefits of REM-fitted hearing aids with respect to patient outcomes that include self-reported listening ability, speech intelligibility in quiet and noise and patients' preference. Our main research question is whether REM-based fitting improves the patient reported outcome measures - PROMs (SSQ, HERE) and performance-based outcome measures (speech-reception threshold in noise) over initial fit approach. An additional research question is whether REM-based fitting improves hearing aid usage (self-reported & log-data report). Eventually, the investigators will calculate the cost-effectiveness of REM-based fitting.

School Screening and Telemedicine Specialty Referral to Address Childhood Hearing Loss in Rural...

Hearing Loss

This trial will evaluate a multilevel intervention (STAR model) that combines mobile health (mHealth) hearing screening tools with telemedicine technology for specialty care access in rural Kentucky schools. An initial version of the model was used in rural Alaska where telemedicine-based specialty referral improved both proportion of children receiving follow-up and time to follow-up. The refined STAR model will utilize an enhanced mHealth screening protocol that includes tympanometry for the detection of middle ear disease. The STAR model will also include a specialty telemedicine referral process in schools for children who refer school screening.

Effects of Clear Speech on Listening Effort and Memory in Sentence Processing

SpeechMemory2 more

Sensorineural hearing loss (SNHL) is among the most prevalent chronic conditions in aging and has a profoundly negative effect on speech comprehension, leading to increased social isolation, reduced quality of life, and increased risk for the development of dementia in older adulthood. Typical audiological tests and interventions, which focus on measuring and restoring audibility, do not explain the full range of cognitive difficulties that adults with hearing loss experience in speech comprehension. For example, adults with SNHL have to work disproportionally harder to decode acoustically degraded speech. That additional effort is thought to diminish shared executive and attentional resources for higher-level language processes, impacting subsequent comprehension and memory, even when speech is completely intelligible. This phenomenon has been referred to as listening effort (LE). There is a growing understanding that these cognitive factors are a critical and often "hidden effect" of hearing loss. At the same time, the effects of LE on the neural mechanisms of language processing and memory in SNHL are currently not well understood. In order to develop evidence-based assessments and interventions to improve comprehension and memory in SNHL, it is critical that we elucidate the cognitive and neural mechanisms of LE and its consequences for speech comprehension. In this project, we adopt a multi-method approach, combining methods from clinical audiology, psycholinguistics, and cognitive neuroscience to address this gap of knowledge. Specifically, we adopt a novel and innovative method of co-registering pupillometry (a reliable physiological measure of LE) and language-related event-related brain potential (ERP) measures during real-time speech processing to characterize the effects of clear speech (i.e., a listener-oriented speaking style that is spontaneously adopted to improve intelligibility when speakers are aware of a perception difficulty on behalf of the listener) on high-level language processes (e.g., semantic retrieval, syntactic integration) and subsequent speech memory in older adults with SNHL. This innovative work addresses a time-sensitive gap in the literature regarding the identification of objective and reliable markers of specific neurocognitive processes impacted by speech clarity and LE in age-related SNHL.

Word Learning in Deaf Children Using Eye-tracking and Behavioral Measures

Deafness

Mutual exclusivity is a word learning constraint in which the learner assumes that a given word refers to only one category of objects. In spoken languages, mutual exclusivity has been demonstrated in monolingual children as young as 17 months and cross-linguistically, while multilingual learners show an attenuated mutual exclusivity bias. Mutual exclusivity has not been robustly demonstrated in deaf children acquiring American Sign Language (ASL). Further, it is unclear if mutual exclusivity applies to those learning both a signed and a spoken language. Like unimodal bilinguals, bimodal bilingual (BiBi) children learn two words for an object, but these words are separated by modality. A BiBi child could therefore assume that all objects have two words (like unimodal bilinguals) or that all objects have one spoken word and one sign (within-modality mutual exclusivity). The goals of the current study are to demonstrate mutual exclusivity in monolingual deaf children acquiring ASL, and to determine if BiBi deaf children utilize mutual exclusivity within each modality.

Apple Hearing Study

Hearing LossNoise-Induced1 more

The Apple Hearing Study is a partnership between the University of Michigan and Apple to study sound exposure and its impact on hearing health. This groundbreaking study will advance the understanding of how hearing could be impacted over time by exposure to sound at certain levels. The investigators will measure headphone and environmental sound exposures over time among participants, and determine how these exposures impact hearing and stress levels. US residents who own an iPhone, download the Apple Research app and consent to participate will be randomly assigned to two groups, one with a "Basic" user interface in the Research app, and one with an "Advanced" user interface. Users in the "Advanced" group will receive additional information about their exposures and be given additional surveys and hearing tests based on their music and environmental sound exposures. The study will provide investigators with a better understanding of listening behavior and its overall impact on hearing health. This information will in turn help guide public health policy and prevention programs designed to protect and promote hearing health in the US and globally.

Hearing for Communication and Resident Engagement

Hearing LossAge-Related

Amplification is a well-established, evidence-based front-line treatment for those with impaired communication secondary to Age Related Hearing Loss (ARHL). ARHL is the most prevalent cause of communication impairment among older adults. The challenge in treating ARHL is identifying a care model that effectively promotes adherence to individualized-treatment recommendations allowing the end-user to self-manage hearing loss with appropriate support. This proposal compares the two most common models of care for ARHL provided to adults in assisted living/personal care communities. The Consult Model (i.e., usual care) is an acute care strategy, relying on a monthly Audiologist visit to the facility. The Engage Model is a chronic care approach to support hearing loss self-management of ARHL. Engage includes (a) hearing screening for all residents, (b) an individualized communication plan for those with an identified hearing loss (e.g., one-to-one, group, telephone, television plans, hearing aid trouble shooting, communication strategies, etc.), (c) provision of simple, non-custom amplifiers, (d) referral to audiology if needed, and (e) ongoing support provided by trained personnel (Communication Facilitator) under the supervision of the audiologist.

Investigating Disinhibitory Brain Mechanism in Tinnitus and Hearing Loss

TinnitusHearing Loss

Tinnitus, the perception of sound in the absence of an external acoustic stimulus. Tinnitus is often perceived inside the head rather than the ear and is a common condition with a prevalence estimated between 10 and 15% in adults. Between 1 and 3% of this population are having a significant impact on their quality of life. Despite its high prevalence, the underlying mechanisms of tinnitus still remain unclear. The majority of tinnitus cases associated with some degree of hearing loss, making hearing loss the biggest risk factor for tinnitus. Recently, it has been suggested that hearing deficits, such as speech-in-noise difficulty, can exist in the absence of any overt hearing loss within the audiometric range (0.125-8 kHz). This is referred to as "hidden hearing loss" and has been suggested to be associated with hearing loss at above-audiometric (> 8 kHz) frequencies. This project is aimed at studying the underlying mechanisms of tinnitus and the possible relation with overt or hidden hearing loss. Specifically, the investigators want to test the hypothesis that tinnitus is caused by maladaptive plasticity arising as a result of auditory input deprivation. This idea is supported by the finding that tinnitus may disappear when the hearing, and thus auditory input, recover. Disruptions at lower levels of the auditory pathway could lead to alterations in synaptic transmission and neurotransmitter release in more central regions of the auditory system (e.g., in the auditory cortex). This may create an imbalance between neuronal excitation and inhibition, and re-routing of auditory pathways, leading to abnormal neural excitability and connectivity. In this study, the investigators question whether auditory cortex disinhibition is specifically related to tinnitus, or is a consequence of hearing loss. To answer this question, the investigators propose to conduct a study that aims to investigate the inhibition mechanism by quantifying GABA concentration level, neural activity and functional connectivity strength of auditory cortex using non-invasive imaging techniques, namely Magnetic Resonance Spectroscopy (MRS) and functional Magnetic Resonance Imaging (fMRI). The investigators expected to possibly provide a tinnitus biomarker, and this may help to direct future treatments.
