Filter by:This Registry represents a non-interventional systematic collection of clinical data in which prospective data from children and adults are collected as fully anonymized data sets, derived from original clinical records on appropriately informed subjects. This is a patient-outcomes Registry for subjects of any age who are provided in routine clinical practice with one or more MED-EL hearing devices. The Registry aims to collect data for hypothesis generation on subject device use, auditory performance, quality of life and health-related utilities, across different types of implantable and non-implantable hearing devices from MED-EL company. Subjects will be evaluated with a set of standardized tests and questionnaires prior to implantation or prior to initial device activation (baseline) and at follow-up intervals according to the clinical practice.
The goal of this project is to compare aided and unaided speech discrimination among infants with hearing loss and a cohort of infants with typical hearing. Working Hypothesis: Among this group of infants with hearing loss, performance will be significantly better when infants are tested while using amplification (i.e., aided condition) compared to when tested without amplification (i.e., unaided condition). Infants fit with optimally programmed amplification will perform similarly to the infants with typical hearing on speech discrimination tasks.
Interest and demand for sound amplifiers are increasing due to the burden of purchasing hearing aids and technological advances in healthcare products, and the demand is expected to increase rapidly. For sensorineural hearing loss patients, who are subject to wearing hearing aids, it aims to compare the effect of hearing aid application and personal sound amplification product (PSAPs) compared to the hearing aids
The purpose of this early feasibility study is to explore several facets of hearing performance that may show improvements for alternative modes of stimulation compared to Monopolar (MP stimulation) in cochlear implant recipients. This study will iteratively evaluate different parameter sets that intend to maximize hearing performance benefits within technical requirements. This study is exploratory in nature and will achieve its objectives through ongoing review and adjustment of device parameters and fitting
The goal of this study is to investigate the role of social factors on speech learning, including production and perception, in infants ranging in age from ~7-18 months. Infants have either typical hearing or sensorineural hearing loss. The main prediction of the study is that social reinforcement will engender improvements in vocal learning above and beyond gains in hearing in infants with hearing loss. As part of this study: - The parent and infant engage in a free play session in the playroom while the investigator cues the parent to say simple nonsense words; - Infants hear playback of the same words during a second phase.
This study is intended to evaluate the ability of SENS-401 to prevent the ototoxicity induced by cisplatin in subjects with a neoplastic disease. It is a multicenter, randomized, controlled, two-arm, open-label efficacy and safety study in adults with neoplastic disease requiring treatment with cisplatin as part of the chemotherapy protocol plan.
Sudden deafness is a sudden, unexplained sensorineural hearing loss of ≥20 dBHL in at least two adjacent frequencies within 72 h. It may be accompanied by tinnitus, a sense of ear congestion, vertigo and other Symptoms.Stellate ganglion block increases the blood flow and blood velocity in the inner ear, keeping the body's vegetative, endocrine and immune functions normal.The branches of the facial and linguopharyngeal nerves are connected to the inner ear, and local injection can nourish the nerves and improve local circulation.
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.
This study will assess safety and efficacy of the MED-EL BONEBRIDGE Bone Conduction Implant in children under 12 years old with conductive or mixed hearing loss.
The protocol has two aims; Aim 1 involves two experiments and Aim 2 involves three experiments. Under Aim 1, the investigator will identify that the frequency and time ranges of consonants produce consonant enhancement (i.e., "target frequency range" and "target time range", respectively), and that the frequency and time ranges of consonants cause consonant confusions (i.e., "conflicting frequency range" and "conflicting time range", respectively). Aim 2 tests the effects of the frequency and time ranges, identified through Aim 1 on consonant recognition with each of the four signal processing conditions: no signal processing (i.e., control condition), the target frequency and time ranges intensified alone, the conflicting frequency and time ranges suppressed alone, and both target range intensification and conflicting range suppression.
