Filter by: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.
Nearly half a billion people suffer from disabling hearing loss. The most common form of hearing loss in adults is age-related hearing loss (ARHL), which causes a reduced ability to understand speech in noisy environments. The ability of people with ARHL to communicate is therefore greatly impacted, limiting their social interactions and thus their quality of life. Yet, the wear of hearing aids - which is the current standard rehabilitation treatment in such cases - does not lead to optimal satisfactory outcomes when it comes to understanding speech in noisy environments. The objective of this pilot study is to test a new signal-processing algorithm, based on artificial intelligence, that aims at enhancing the intelligibility of speech-in-noise signals. The efficiency of the algorithm is compared to a standard denoising algorithm commonly used in hearing aids. The primary outcome measure is the word-identification performance of the participants, using the FrMatrix test (Jansen et al., 2012). Two secondary outcome measures are investigated: listening effort (self-assessed using a Likert scale, and measured through response times), and subjective preference (assessed in a paired-comparison task). The study is conducted in 20 normal-hearing subjects and in 40 older (age ≥ 55 years) hearing-impaired subjects.
This study is a prospective, randomized pilot study. To verify an efficacy and safety of the Intratympanic drug delivery vehicle, patients who have not responded to the existing standard treatment will be enrolled. Hearing test, endoscopy of tympanic membrane and CT scans will be conducted after intratympanic treatment for evaluation.
In France, children cochlear implantation (CI) is performed 400 times per year. Causes of profound sensorineural hearing loss (SNHL) are represented by congenital malformation of the inner ear for 50 to 60%. Most of the remaining cases of CI in children are caused by congenital CMV infection. The proportion of CMV inducing SNHL with a CI in children is not clearly defined. During CI, we aim to collect a very small sample of perilymphatic fluid and to analyse it with a CMV polymerised-chain-reaction to evaluate the involvement of CMV in SNHL.
The current study is a randomized multi-center clinical trial that investigates the role an intraoperative hearing monitoring system (electrocochleography) has on helping to save residual hearing in patients undergoing cochlear implantation (CI).
This is a prospective study designed to evaluate the safety and performance of the HiResTM Ultra Cl HiFocusTM MS Electrode and HiResTM Ultra 3D Cl HiFocusTM MS Electrode (Ultra X) under normal conditions of use as it is approved for this device.
The objective of this application is to develop and evaluate Spanish-language hearing education materials for adults. Our hypothesis is that participants will demonstrate better understanding of their hearing loss and associated difficulties, and will be better able to identify options for self-management following delivery of culturally and linguistically appropriate patient education materials.
Age-related hearing loss, presbycusis, affects up to 50% of American adults. There are two main causes for presbycusis: 1) Progressive death of hair cells in the inner ear, and 2) Central hearing loss, or the reduced ability to decipher the sound source of interest from other competing sounds in a multi-source complex environment. The first cause is better understood and treatment options, such as hearing aids and cochlear implants, are available. However, central hearing loss is not as well understood and there is not a treatment available at this time. This study aims to advance our understanding of central hearing loss by evaluating the abilities of younger and older listeners in two primary outcome measures: to 1) neurologically process sound stimuli and 2) focus on conversational speech in the presence of spatially-separated competing background noise. A test using Auditory Brainstem Responses (ABR) will be used to evaluate the brain's response to clicking sounds. This study will assess all waveform data, but will focus particularly on wave III. Sentence in noise tests will be used to assess each subject's ability to process speech in noisy situations. Both the ABR and sentence in noise tests are non-invasive and are commonly used in audiology practices to diagnosis and treat a variety of audiological pathologies.
The purpose of the study is to evaluate the long-term safety and effectiveness of cochlear implantation of the approved population in adults and children with single-sided deafness and asymmetric hearing loss.
Background: Hereditary hearing loss is one of the most common sensory disabilities affecting newborns. The main options for people with hereditary hearing loss are hearing aids and cochlear implants. Both options have their limitations and do not restore biological hearing. Researchers want to learn if gene editing might be a treatment option. Objective: To understand the genes that cause non-syndromic autosomal dominant hearing loss (DFNA) in people with DFNA as well as their family members. Eligibility: People age 3 99 who have DFNA, affected family members of enrolled participants with DFNA, and unaffected family members of enrolled participants Design: Participants will be screened with a medical and hearing history. Their medical records will be reviewed. Participants will have hearing tests. They will wear headphones or earplugs. They will listen to tones, sounds, and words and may be asked to describe what they hear. Participants will have balance tests. For these, they will wear googles as they watch moving lights or as cold or warm air is blown into their ears. They will sit in a spinning chair in a quiet, dark booth. From a reclined position, they will raise their head while listening to clicking sounds. Participants will have blood drawn through a needle in the arm. Some blood will be used for gene testing. Some participants will have 2 skin biopsies. The skin will be washed, and a numbing medicine will be injected. Two small pieces of skin will be removed. Participants may have a physical exam. Participation will last for up to 20 years. Participants may give medical updates once a year.
